That's the engine setup that people should pit against the 450 4T... That's got to be a CR, KX, & anything else destroyer. I can't believe someone did it, finally! 👏🏼😮👍🏼
@@jr5762 300 2 strokes are maybe faster on the MX track and even more so in long enduro races but that does not mean they have more or same power :) ... I did try a KTM 300 2 stroke and it was real fun but it lacked power at all RPM and specially at bottom compared to my old Yamaha WR450 so I ender up with a 2019 KTM 500 EXC F and the power on that thing is way more then on the 300 2 T :) Strange thing is that when riding slow the 500 feels pretty much identical to the 300 2T and the weight difference is only a few kg (2 or 3KG if I remember correctly). What I really want to try is a modern vibration less 500 2 stroke like the KTM 300 but with more power :)
What a sound, it reminds me of my youth when 500 were the way to go. It took a special kind of riders to utilize that 500cc power...the kind of men, with large stones and a heart of steel...It was not my case; my stones were too tiny ;)
Mine too - I had a ‘89 cr 500 that I used to ride most days , sold it in ‘93 and regretted it every day since! Ps are you a Henry fan? My father was in the army with him
@shawnszep4941 no they aren't.... They're an amazing kit and extremely popular! Now if you used the stock ECU and/or jetting, then there's your issue...you can't have a ignition mapped for say a YZ250 or something for an example, and expect it to work on a 500. Get a Vortex ignition or the ECU shown in the video, get it mapped for the 500 along with your other mods to maximize those, along with a 40mm Jet-less SmartCarb with a TPS sensor, and pick a good pipe for the kit...I have a custom cone pipe for the 500 that's similar to an FMF fatty, with a Ti/Carbon shorty combo...Boysen RAD valve kit, Loudmouth intake, a Phat Head with the MX dome insert ported specifically for race gas (haven't ever tried the SX dome insert) 13/50 gearing. The BRC kit uses CR500 pistons as direct replacement parts for easy parts availability, the kit has an auto decompress and when it fires it automatically closes. So it's like the CR500, just made as direct drop in kit without any frame, subframe, water hoses, intake medications to get it to fit like the other CR500AF conversions, and there's no worry of the front sprocket not being directly in line with the rear, or engine tilt being off like what can happen trying to squeeze a whole CR500 engine into your frame of choice, then making engine mounts/hangars, and cutting/rewelding the frame, which can potentially weaken it, aswell as changing the frames flexcharacteristics/rigidity. It just uses your donor bikes transmission (which I had tumbled/micro polished), clutch that I replace with a Rekluse slipper clutch, put a boysen high flow water pump/impeller kit...the only bummer is I broke 2 kick start gears because of the compression, luckily they came out with a good fix for the YZ250 using a much stronger gear. The bike absolutely rips, i raced 'A' class as an amateur and its easily fast enough for me...I can lug it like a 450 if I want, or ride it in the meat of the power and with my suspension guy who's done 500 conversions before, he got me the right spring rate and valving/shim stacks to get my KYB SSS forks and shock working amazingly well and balanced. It already had Ti-Nitrate lowers, black fork lugs, Kashima coated uppers, and X-Trig split triple clamps. Also got some titanium engine hangers, and all the other bits and pieces from when my YZ250 was my race bike. The crank was also weighted and balanced so like the newer KTMs, there was barley any vibration and I also have rubber mounted bar mounts to decrease the vibration even more...So you don't have to worry about doing a full bolt check after ever 30min+2 practice moto because normally a 500 will vibrate itself apart. I also have an extra wheel set with a paddle tire for the dunes, it's a monster out there when you can just let it eat. So yeah, something was wrong with the one you rode, it wasn't the kit that was at fault.
I did test drive a 2017 KTM 300 2 stroke and it was real fun to ride when you hit that power band, very additive feeling :) Only problem was I wanted more, it had much less power then my old Yamaha WR450F so I ended up with a 2019 KTM 500 EXC F that I am very happy with. But it is not as exiting as a 2 stroke and it does vibrate unlike the new 300 2 strokes with balance axle that have practically speaking no vibrations at all from the engine. I would probably love a modern 500 2 stroke with balance axle :)
Barry I am going to have to come to Alaska and ride with you! We talked after you had Adam do your suspension! He gave you my contact info about the Smartcarb I was running! I've seen that BRC 500 and have been dying to ride one. I really think I want to build one but don't want to put it in my six days chassis!
I appreciate the use of the longer silencer, I can't help but wonder what the gains would be with a shorty.....for off-road purposes of course, perhaps a comparison video is in order? I know it really doesn't need more power, just curious where it would move, and if it would be an improvement, or detriment. Nice job boys. Keep it up. Can we get some more on that billet smart carb.?
Its a 40mm billet SmartCarb with a throttle position sensor. The throttle position sensor is used with a PowerCDI ECU. The PowerCDI ECU has a custom ignition map for the BRC 500. In addition the PowerCDI has the capability (not currently set up) for Dynamic Power Control, a form of engine power management based in dynamic ignition mapping and throttle position/movement. In addition it has the capacity to acquire dyno data for use in re-mapping when desired. The SmartCarb compensates for altitude changes, vitally important in a snow bike, and yields significant increases in fuel economy, not to mention good cold starting. A recent ride (yesterday) by the owner provided 4 hours of riding in deep and heavy snow conditions (he calls it "mashed potatoe snow") while using 2 gallons of fuel. Overall, the SmartCarb with TPS/PowerCDI combo on the BRC500 platform is working well above expectations.
Thank you for sharing. I have been watching these for a few weeks now. Want one so bad I can smell the motorex and leaded fuel in my sleep! Any idea of the nuanced differences between the 2019 chassis and the chassises that BRC recommends for these motors ?
Personally I think the 2017 and up chassis is far surperior and lighter. But TPI on most of the newer 250-300 models is limiting the market, so I guess they focused on the 2008-2016 models that are already out there. The good news is that BRC is planning on developing a 500cc kit for the 2017-and-up market too, as not all of the variations of the 250-300 bikes are going to get TPI. Some are still carbed.
Barry Jackson it appeared to need feathering the throttle constantly like my 500 Honda did no matter what rod or vent checks were installed. Sounds like you got it sorted out.
What are you using the bike for... just wondering. I just hope you keep us posted because no one online has proper footage, other than the usual suspect and your setup is above & beyond for controlling the big bore. Thanks
Yes, we will post more footage. We have a number of additional bits of footage taken during the build effort, including some small issues or additions to the kit that we thought would enhance the build experience. We're hoping to get some trail footage today. Since this particular build will be done in the next few days, aside from the coming snow bike aspect, I will be freed up the do the necessary editing. I'm not a pro at this so the videos will likely be the same amateurish quality. We are just trail riders, so our choices are guided by what we need for that use. Mostly tight, twisty, rooty, sometimes swampy single and two track with some really nice fast and flowing two track, as in how fast do you want to go kind of two track. My engine kit will be next and there will be video coverage of it also.
Here's a link to Technology Elevated, manufacturer of the SmartCarb line of carburetors. TPS is Throttle Position Sensor, which means that with the right electronic components, the throttle position being held on the SmartCarb can be determined and an electronic signal can be sent to an engine control unit (ECU) which can then instruct (electronically) other elements of the fuel and ignition system how to react.

It's being used as a snow bike at the moment. Here's a link: ruclips.net/video/LJCTeOmM6zA/видео.html In the description it was noted that on this ride it was ridden for 4 hours without going on reserve (with the SmartCarb and PowerCDI). We don't know what to expect in the summer, but it's likely to be similar. If that turns out to be true, then the mileage with the summer setup should approach 75 miles - 90 miles on a standard 2015 XCW tank (which I think was 2.8 gallons).
Congrats and great work. Nice to see it done on a Husky/KTM; I was thinking about doing something similar (and maybe use a Lectron). How much has it cost so far?
You need a donor bike or engine (maybe from your current ride), and the engine kit. The engine kit cost about $5800 USD. Spending above and beyond that is dependent on how much bling snd updating you want to do.
@@barryjackson9917 awesome, ill probably catch upcoming videos cause this BRC intrigues me, i rebuilt a 97 ktm 250 egs a half decade ago and love 2 strokes ("that 300 goes pretty good, what year is it?" haha), also that smartcarb is a great thing, especially if you take the bike to different altitudes or temperatures. i wonder if it ever has a problem leaning out in the cold or fouling plugs on a hot day. ive been anticipating a mainstream release of an EFI or even better direct high pressure injection model from ktm the last few years now and it never came. with emission regulations getting tougher i thought it was the logical progression - but it would boggle the minds of all the 4 smoker fans if 2 strokes suddenly had less emissions, more bottom end to mid-range power and better fuel economy. XD it would create a market rush from all the envy and disappointment. 2 strokes are just better, and people have to face it. twice as many power strokes is atleast 1.5x the power :) ps. once the rims are back on, id love to see a motocross start with it, and a hard and fast burm to really hear how the thing sings. i know its not quite like a 250 in that regard and big bore 2 strokes still do produce alot of power lower in the rev range. something interesting i heard is that honda produced a fuel injected 400cc 2 stroke that raced in dakar in the 80's or something. you're re-invigorating my quest hahaha. cheers,
@@kinglouis6974 It's a programmable ECU that is connected to a Throttle Position Sensor (TPS). The TPS is an add-on option to the SmartCarb. The ECU reads the throttle position and the amount of throttle change over time (it can read changes fast enough to adjust timing in a single revolution of the engine). Based on how the throttle is being operated and the concurrent RPM, it can adjust timing to retard or advance, affecting power output based on the dynamic relationship between the throttle and rpms.
Barry Jackson but I alway thought ecu was to do with injection and the ecu would change the fuel so no choke , all that mod you put on can do is change the timing ?? Thanks for the info 🏴👍🏼
@@kinglouis6974 The SmartCarb takes care of the mixture better than an injector once its set; it does altitude compensation automatically. The PowerCDI ECU provides 3 times the spark voltage and provides Dynamic Power Control (DPC) by instantaneously varying the timing to suit the rider's throttle inputs.
Yep, it's not cheap, but it's not 11K either. The engine kit is about $5800 USD. You don't have to do the SmartCarb nor the PowerCDI, but if you do add another $1700 USD. With all 3 it's about $7500 USD, but you do have the best of the best.in my opinion.
I assume if you want a kit like this that you already have a donor bike. If not, then yes, you'd have to add the cost of a donor bike. I already have a donor bike - my 2015 300 XCW, so that's not an issue for me.
Yes, the 1st few rides tend to be that way as you are assessing what has been accpmplished and doing the break in chores, but also on that day the trails were very wet and this riding area is infamous for being slick clay when its wet. Stay tuned for some snow bike videos where we get the opportunity to rev it out a bit while we are assessing the additional setup work needed for that kind of riding.
It’s pretty cool I do have to say but I don’t get it. You don’t need a 500 for anything that bike with the stock 250 motor was good so my question is why the 500? I’d imagine you have the cost of a new bike just in the motor. Again I’m not dissing at all I think it cool as hell!!!!! I’m just looking at the cost and comparison someone said it 7500 just for the motor of course I don’t know if that’s true. Either way it’s sick and if it becomes affordable all the better!!!!!
Yeah, the stock bike was pretty dang good. But if you have the money and have never ridden an old-timey 500, and it can be converted to a snow bike for the winter season (where the extra power of the 500 motor is an undeniable improvement over the 250 or 300), and you get a very modern counter-balanced electric starting motor, why not? And the power output of the motor is aimed at trail riding vs. MX (not that it won't do well as a modern MX machine), so even better. The USD cost is right at $5800. It's real easy to spend that much on an off-road bike without obtaining the massive character change that comes with the 500 motor. We didn't get enough trail time before the snow fell last fall, but the little time we did get held a lot of promise that this is going to be a monumental trail bike. If you're an off-road racer, perhaps it would meet your needs well and perhaps not. Kinda like some off road races are more suited to a trials bike while others are more like Dakar.
Barry Jackson I race at a high level and would never choose a 500 period no matter how it’s tuned it’s just to much, to much weight to much power for a 3 to 4 hour race. On my 300 I have a map switch to smooth the power out at end of races to conserve energy. I don’t see a 500 working out east where I am or on national enduro scene. Now maybe in the desert I don’t have a lot of experience there I’ve only raced a few times out west and used a 450 saying that it was pinned most of the time. Now a snow bike I can totally get I live in northern mi we get a lot of snow I have 3 ft at my house and across the bridge we have 5ft plus and everyone is looking for more power with there snow bike. It’s cool though like putting a big block in a s-10. You all did a professional job also it looks stock pretty much.
Barry Jackson though I don’t agree with undeniably better than a 250 or 300. There is a reason no one makes a 500 anymore. Again I really like the build it’s awesome please don’t think I’m being a dick or hating you did a wonderful job and it’s bad ass build. This is all my personal opinion I’ve never ridden that bike and it could be the best thing ever this is just my thoughts and I’m a moron lol .
Not taking offense here... but if you re-read my earlier reply I was talking about snow bikes when I mentioned its improvement over a 250 or 300. While one could put this motor into a modern KTM MX frame (up to 2016?), it's specifically designed to fit in the the XCW & XC frames from about 2008 to 2016. So, it's power and delivery is aimed at off-road pursuits, and not MX. This is exactly the opposite of the old days of the 500 bikes. They were all MX aimed bikes in both riding/handling and power delivery. In those days, if you rode a 500 as a trail bike, you were riding a motocross bike on the trails - not ideal. With the BRC 500 you are installing it in a trail-oriented bike with modern and appropriate weight and handling characteristics. The cost is about an 8 pound weight increase. With the PowerCDI there is the ability to add DPC (Dynamic Power Control) in the future to allow a very well-managed power delivery for trail difficulties. Will it be competitive? Who knows? Will it be fun? Oh, yeah! And for what it's worth, the reason the 500 2-strokers aren't being made anymore is most directly due to rules changes sought by 4 stroke MX engine manufacturers to allow 4 strokes to compete. The rules were changed to cut the 500cc 2 strokes down to 250s so the 4 strokes of the day might be able to compete. Then the manufacturers stayed focused on developing the 4 strokes and basically abandoned 2 stroke development. One of the things the BRC 500 proves is that had the 500 2 stroke motors continued to be allowed they would still be way more powerful than the best of the modern 4 stroke motors. The best 4 strokers are making at or near 60 hp today (factory racers maybe a bit more). The BRC 500, as a brand new 2 stroke motor, is already making 72 hp and some have said it has been seen to produce 77 hp. Can you use all that horsepower? I sure don't know, but I'm really looking forward to finding out, especially when DPC is functional . Worst case, I'll stick with my 2017 300 XCW for most rides. It's all fun...
@@barryjackson9917 thanks for the reply sir. That make sense regarding"smart carb" im gonna Google here shortly 10 of 7 eastern time, but I gather it's gravity fed carb... Sounds intriguing, also im certain you can strap that BRC into anything you want, they sell it as "for 250 / 300 ktm's but hell. With a wiz wheel and a mig... 😁 GREAT POST. get some more of that out ppl want to see that for sure. 👍
It all depend of where you ride and what type of riding and it is also just fun to have power to play with even if you almost never "need" it :) For some types of riding you have no problem using all a 500 4T has to offer with no problem even for an inexperienced rider like me. I did test ride a KTM 300 2 stroke and found it lacking in power compared to my old WR450 so now I have a 4 stroke 2019 KTM 500 EXC F. But it would have been nice to have a modern 500 2T with balance axle for a vibration free ride with even more power then the 500 4T :) Big 2 strokes is addictive because they are challenging and more exiting to ride then anything else, not because they are easy to ride :)
elcontrastador Jeez some people are dicks. He hasn’t got a lid on, he’s riding on the street where his neighbours live, the engine is cold, and the clutch isn’t right.
Thanks for the comment Dirt Speed918. I WAS about to fall asleep; sharp of you to notice. Too many late nights building the bike and shooting and editing the videos I guess. That, plus being an amateur can sometimes produce amateurish results. I would appreciate your feedback on this... should I stop putting out any further videos on this build if they continue to be of the same amateurish quality as this one (and the other 9)? I have one more BRC 500 build to do this Spring and it sure would be nice to find out whether producing videos, given my amateurish capabilities, will be worth the effort. If the time it takes isn't worthwhile, the videos are part of the effort that would be easy to ditch. I'm serious Dirt Speed918... should I stop putting out these videos if I can't make them more professional?

Runs pretty good for a 500cc twostroke👍.
How long can you ride with the 9,5 L fueltank?
It's being used as a snow bike at the moment. Here's a link: ruclips.net/video/LJCTeOmM6zA/видео.html In the description it was noted that on this ride it was ridden for 4 hours without going on reserve (with the SmartCarb and PowerCDI). We don't know what to expect in the summer, but it's likely to be similar. If that turns out to be true, then the mileage with the summer setup should approach 75 miles - 90 miles on a standard 2015 XCW tank (which I think was 2.8 gallons).
I wonder how long the transmission will hold up.
I guess we'll see. We're trail riders, so we are probably not going to be stressing it to the limit.
I’m sure it will be fine the gears are pretty strong
Transmission would be fine. I would worry more about the clutch. More curious to see if the clutch can hold the power...
that's badass
What are you possibly going to do with that boy out are 2 old for that sounds just like a 250
Very nice Barry....did you choose steel frame because the aluminum would crack?
B@$!© B®0 they dont make aluminium frames.
@@adamberggren5815 I'm saying over a bike with an aluminum frame like a Honda
B@$!© B®0 the engine is a reworked ktm/husky engine so it fits directly into the frame thats why.
@@adamberggren5815 cool
Sounds clean/ cripsy ass sound🗣🗣🥵
Congrats and great work. Nice to see it done on a Husky/KTM; I was thinking about doing something similar (and maybe use a Lectron). How much has it cost so far?
You need a donor bike or engine (maybe from your current ride), and the engine kit. The engine kit cost about $5800 USD. Spending above and beyond that is dependent on how much bling snd updating you want to do.
What's up with the idle does? Does it idle?? 😂😂
Oh yeah. Here's a cold-start and idle as a snow bike. We're now converting it back to a summer trail bike. ruclips.net/video/-w9J8W-hIvg/видео.html
Yeah sounds like crap! Idk what everyone else on the comments are smoking. Almost stalled everytime it wasn't rev'd up..
i want to hear you rev it out?! i hope you dont ride it outside of the power in your other vids. ill check
Check out the vid with "Petersville" in the title - It's run hard as a snowbike. We're just now converting it back to a trail bike.
@@barryjackson9917 awesome, ill probably catch upcoming videos cause this BRC intrigues me, i rebuilt a 97 ktm 250 egs a half decade ago and love 2 strokes ("that 300 goes pretty good, what year is it?" haha), also that smartcarb is a great thing, especially if you take the bike to different altitudes or temperatures. i wonder if it ever has a problem leaning out in the cold or fouling plugs on a hot day. ive been anticipating a mainstream release of an EFI or even better direct high pressure injection model from ktm the last few years now and it never came. with emission regulations getting tougher i thought it was the logical progression - but it would boggle the minds of all the 4 smoker fans if 2 strokes suddenly had less emissions, more bottom end to mid-range power and better fuel economy. XD it would create a market rush from all the envy and disappointment. 2 strokes are just better, and people have to face it. twice as many power strokes is atleast 1.5x the power :)
ps. once the rims are back on, id love to see a motocross start with it, and a hard and fast burm to really hear how the thing sings. i know its not quite like a 250 in that regard and big bore 2 strokes still do produce alot of power lower in the rev range. something interesting i heard is that honda produced a fuel injected 400cc 2 stroke that raced in dakar in the 80's or something. you're re-invigorating my quest hahaha. cheers,
How does that ignition mod work if the bike is running a carb is it a CFI set up ?
Oh it’s obviously a carb it has a choke, but still again what does that mod do ??
@@kinglouis6974 It's a programmable ECU that is connected to a Throttle Position Sensor (TPS). The TPS is an add-on option to the SmartCarb. The ECU reads the throttle position and the amount of throttle change over time (it can read changes fast enough to adjust timing in a single revolution of the engine). Based on how the throttle is being operated and the concurrent RPM, it can adjust timing to retard or advance, affecting power output based on the dynamic relationship between the throttle and rpms.
Barry Jackson but I alway thought ecu was to do with injection and the ecu would change the fuel so no choke , all that mod you put on can do is change the timing ??
Thanks for the info 🏴👍🏼
@@kinglouis6974 The SmartCarb takes care of the mixture better than an injector once its set; it does altitude compensation automatically. The PowerCDI ECU provides 3 times the spark voltage and provides Dynamic Power Control (DPC) by instantaneously varying the timing to suit the rider's throttle inputs.
Only a 500 2stroke Sounds like a 500 2stroke 😍😍 fuck up that 4stroke shit
All that and it still doesn't fire on 1st kick?
That's what I'm saying?!?! Sounds like shit too.. Husqvarna chainsaws are junk too. Would never buy a Husqvarna...
Soon as I get an extree $11k. Lyin round I'm ALL IN!
😆😆😆😁😁😃😃😃😄😄😄🤩 The husky seems better than the KTM in all seriousness
Yep, it's not cheap, but it's not 11K either. The engine kit is about $5800 USD. You don't have to do the SmartCarb nor the PowerCDI, but if you do add another $1700 USD. With all 3 it's about $7500 USD, but you do have the best of the best.in my opinion.
@@barryjackson9917 well you also need a husky right?
I assume if you want a kit like this that you already have a donor bike. If not, then yes, you'd have to add the cost of a donor bike. I already have a donor bike - my 2015 300 XCW, so that's not an issue for me.
Is it street legal?
Hes riding like its a 4 stroke
Yes, the 1st few rides tend to be that way as you are assessing what has been accpmplished and doing the break in chores, but also on that day the trails were very wet and this riding area is infamous for being slick clay when its wet. Stay tuned for some snow bike videos where we get the opportunity to rev it out a bit while we are assessing the additional setup work needed for that kind of riding.
Snowbike?? 🤑
It’s pretty cool I do have to say but I don’t get it. You don’t need a 500 for anything that bike with the stock 250 motor was good so my question is why the 500? I’d imagine you have the cost of a new bike just in the motor. Again I’m not dissing at all I think it cool as hell!!!!! I’m just looking at the cost and comparison someone said it 7500 just for the motor of course I don’t know if that’s true. Either way it’s sick and if it becomes affordable all the better!!!!!
Yeah, the stock bike was pretty dang good. But if you have the money and have never ridden an old-timey 500, and it can be converted to a snow bike for the winter season (where the extra power of the 500 motor is an undeniable improvement over the 250 or 300), and you get a very modern counter-balanced electric starting motor, why not? And the power output of the motor is aimed at trail riding vs. MX (not that it won't do well as a modern MX machine), so even better.
The USD cost is right at $5800. It's real easy to spend that much on an off-road bike without obtaining the massive character change that comes with the 500 motor. We didn't get enough trail time before the snow fell last fall, but the little time we did get held a lot of promise that this is going to be a monumental trail bike. If you're an off-road racer, perhaps it would meet your needs well and perhaps not. Kinda like some off road races are more suited to a trials bike while others are more like Dakar.
Barry Jackson I race at a high level and would never choose a 500 period no matter how it’s tuned it’s just to much, to much weight to much power for a 3 to 4 hour race. On my 300 I have a map switch to smooth the power out at end of races to conserve energy. I don’t see a 500 working out east where I am or on national enduro scene. Now maybe in the desert I don’t have a lot of experience there I’ve only raced a few times out west and used a 450 saying that it was pinned most of the time. Now a snow bike I can totally get I live in northern mi we get a lot of snow I have 3 ft at my house and across the bridge we have 5ft plus and everyone is looking for more power with there snow bike. It’s cool though like putting a big block in a s-10. You all did a professional job also it looks stock pretty much.
Barry Jackson though I don’t agree with undeniably better than a 250 or 300. There is a reason no one makes a 500 anymore. Again I really like the build it’s awesome please don’t think I’m being a dick or hating you did a wonderful job and it’s bad ass build. This is all my personal opinion I’ve never ridden that bike and it could be the best thing ever this is just my thoughts and I’m a moron lol .
Not taking offense here... but if you re-read my earlier reply I was talking about snow bikes when I mentioned its improvement over a 250 or 300. While one could put this motor into a modern KTM MX frame (up to 2016?), it's specifically designed to fit in the the XCW & XC frames from about 2008 to 2016. So, it's power and delivery is aimed at off-road pursuits, and not MX.
This is exactly the opposite of the old days of the 500 bikes. They were all MX aimed bikes in both riding/handling and power delivery. In those days, if you rode a 500 as a trail bike, you were riding a motocross bike on the trails - not ideal. With the BRC 500 you are installing it in a trail-oriented bike with modern and appropriate weight and handling characteristics.
The cost is about an 8 pound weight increase. With the PowerCDI there is the ability to add DPC (Dynamic Power Control) in the future to allow a very well-managed power delivery for trail difficulties. Will it be competitive? Who knows? Will it be fun? Oh, yeah!
And for what it's worth, the reason the 500 2-strokers aren't being made anymore is most directly due to rules changes sought by 4 stroke MX engine manufacturers to allow 4 strokes to compete. The rules were changed to cut the 500cc 2 strokes down to 250s so the 4 strokes of the day might be able to compete. Then the manufacturers stayed focused on developing the 4 strokes and basically abandoned 2 stroke development.
One of the things the BRC 500 proves is that had the 500 2 stroke motors continued to be allowed they would still be way more powerful than the best of the modern 4 stroke motors. The best 4 strokers are making at or near 60 hp today (factory racers maybe a bit more). The BRC 500, as a brand new 2 stroke motor, is already making 72 hp and some have said it has been seen to produce 77 hp. Can you use all that horsepower? I sure don't know, but I'm really looking forward to finding out, especially when DPC is functional . Worst case, I'll stick with my 2017 300 XCW for most rides. It's all fun...
Barry Jackson all good points
I think that is not enought power :D
persettäkatuun You want to backflip shortly from the start?😂😂
@@ED-on8to idle = wheelies = enought power :D
Suomi torille
Yaay
BTW sounds like he left the choke on there for a minute... I wouldn't run ethanol gas through that puppy either no way
That was without having dialed in the SmartCarb. No ethanol gas here as far as I know.
@@barryjackson9917 thanks for the reply sir. That make sense regarding"smart carb" im gonna Google here shortly 10 of 7 eastern time, but I gather it's gravity fed carb... Sounds intriguing, also im certain you can strap that BRC into anything you want, they sell it as "for 250 / 300 ktm's but hell. With a wiz wheel and a mig... 😁 GREAT POST. get some more of that out ppl want to see that for sure. 👍
she dont like to idle
Сильно "гремит" поршень! Вам нужен поршень со смещением пальца от оси цилиндра. На ваш диаметр поршня смещение 1,5-1,8 мм от оси.
Id say toss the starter in the trash....
Y'all just gonna ride up and down the street on that beast, or take it out in the dirt somewhere and let it eat? Lol
Here's some footage when it was set up as a snow bike. It's now being converted back to a trail bike. ruclips.net/video/LJCTeOmM6zA/видео.html
There some leak from the pipe
What is the actual purpose of these 500 2strokes, 95 percent off people can't even use the power off a 500 4stroke.
The grins on the 5%.
Fun. Summer. Winter.
@ lol u must be American.
It all depend of where you ride and what type of riding and it is also just fun to have power to play with even if you almost never "need" it :) For some types of riding you have no problem using all a 500 4T has to offer with no problem even for an inexperienced rider like me. I did test ride a KTM 300 2 stroke and found it lacking in power compared to my old WR450 so now I have a 4 stroke 2019 KTM 500 EXC F. But it would have been nice to have a modern 500 2T with balance axle for a vibration free ride with even more power then the 500 4T :) Big 2 strokes is addictive because they are challenging and more exiting to ride then anything else, not because they are easy to ride :)
yes you are right... that 5% remaining, though...WhooHoo!!!
HAHAHAH! 20 MPh at 800 rpm
Pipe is leaking
Yep. Prototype pipe had no O-rings. Production pipe has o-rings and does not leak.
He's not safe on it.
all that and he didnt even get it on the pipe screaming FLOP.
You know nothing about breaking a engine in. More than likely you don't have 2 Pennies to rub together.
In 2t not use engine to stop only brakes poor bikers
That smart carb doesn't seem so smart
Never even got on the pipe or even cleared it out after start up. Sounds like 4-stroke riders that have never ridden 2-strokes.
elcontrastador Jeez some people are dicks. He hasn’t got a lid on, he’s riding on the street where his neighbours live, the engine is cold, and the clutch isn’t right.
Please get a different guy to describe the bike the one you is about to fall asleep
Thanks for the comment Dirt Speed918. I WAS about to fall asleep; sharp of you to notice. Too many late nights building the bike and shooting and editing the videos I guess. That, plus being an amateur can sometimes produce amateurish results.
I would appreciate your feedback on this... should I stop putting out any further videos on this build if they continue to be of the same amateurish quality as this one (and the other 9)? I have one more BRC 500 build to do this Spring and it sure would be nice to find out whether producing videos, given my amateurish capabilities, will be worth the effort.
If the time it takes isn't worthwhile, the videos are part of the effort that would be easy to ditch. I'm serious Dirt Speed918... should I stop putting out these videos if I can't make them more professional?
Husqvarna chainsaws are junk. Couldn't pay me to buy a noobie Husqvarna dirkbike...
