That slot canyon that you were riding up through is incredible. I would love to riding that sometime.
It’s so much fun
I usually just twist the throttle a few times as I go down hill to clear it out and that solves most of the loading up problems. I do the same thing with my Xtrainer (don't know it it's necessary; old habits). I want to go riding! That sounds really fun. Hopefully the weather holds out for more riding without spikes in tires.
Lot's of great info here!!! I'm a new sub of just about 2 months and have already watched hrs upon hrs (I actually put on one of your longer ride vids in the background and watch/listen to it as I work on my bike! LOL I usually look when you let out one of your patented yells! LMAO). Learned so much from you and the channel in such a short amount of time! Keep the vids coming!
Thanks so much
Thanks for all this stuff you do Sir. Great sound /audio too btw. 🤘🏽🐸
Thanks
Had a lot of issues with my Lectron on my ‘17. Too lean, too rich, I was adjusting all the time, tried 3 or 4 different metering rods…. Mikuni with JD o-rings was more consistent and noticeably more power.
On my ‘19 did JD o-rings and jet kit and bikes a fire breather. Ridden 1000’ to 10,000’ w/ only an air screw adjustment. 🤷🏻
Agree man. I like normal carbs
I had the same JD oring change on my 2017 ktm with Mikuni carb and it run very well, actually really consistent.
If I had to be honest with you Morgan I would say go back to your 36 mm carburetor. Always love watching your comparison videos thanks for sharing your information and your knowledge is always 🤘🤘
I’m going to keep tuning this carb until I can’t make it better. If it’s still not awesome I’ll switch back
I'm coming to Montrose to ride one way or another! Good luck on the 20K.
Thanks.
The tbi sounds sooo awesome. I love the new bike. Great video as always! Duuuude! No way! Can’t wait for 20k subs!!!
Thanks. Yeah that bike just barks!!
Love that high desert terrain, hoping I can join you on that giveaway ride or just meet up next time I visit the ol' pops there in Montrose.
Heck yeah
Interesting video I love it. Highland people hike up there and take walks but it looks like in the middle of nowhere
It’s really not far from roads
I love my SC2 on my Sherco. I’d love to see this carb compared to a SmartCarb2 and an Electron on the same bike or identical bikes.
That X ting sounds like every smart carb I've ever tried... dang, was hoping it was gonna be good
I feel the same way
It sounds pretty crappy, but is right off Aliexpress... I'd like to see the TBI compared to a well jetted Keihin. The TBI sounds very clean.
Nice video! If my crew meets up with you and you put up with us while we are riding out there, I am buying you dinner and beers at Horsefly, cuz I love that place and you will have earned it 😀 Have ridden all those trails, Horse is a tuff one for sure!
Strange that a bowl vent isn't included with the XTNG carb. If it had a vent, this carb sounds like it would be perfect. I have 36mm Lectron on my 300, it has a bowl vent and no loading up issues. Pleased with the Lectron now that it is dialed in, but I covet those external adjustments and the apparent ability to use the stock throttle cable, as the one that comes with the Lectron is rather cheesy. The original spring that came with my Lectron was stupid stiff too, fortunately they offer a softer spring.
To be honest, now that I know all about the jet block gasket fix, "Jarvis Mod" and of course JD jetting, I would do all the fixes and jetting, and stick with the stock Mikuni on the older carbed bikes. As delivered the stock carb is an absolute mess with that silly needle and leaking jet block gasket. I did all the carb fix and jetting stuff to a friend's '17 300 and it runs great. The jet block fix hadn't really been figured out yet when I sprung for the Lectron back when I bought my 300. That is too bad, could have saved the Lectron money, but whatever at this point. It is on there, it works and I am at the if it ain't broke so don't fix stage, but I will take it off and sell it separately when I sell the bike someday.
I do think the metering rod copes better with elevation and temp changes better than the stock carb, at least that has been my experience, having ridden in freezing weather to 90 plus and from 4K to 12K elevation with good results, but at this point I don't see any of the aftermarket carbs as being really "necessary". Better to spend the carb money on TBT suspension instead!
Amen. Or a new TBI bike. Holy moly!!
@@highlandcycles Or a new TBI with TBT -😆
YES
Cool video been curious about that XTNG carb for a while now. Isn't that a rough trail for hiking?
Pumped for the giveaway man that’s an awesome prize
What a beautiful place to ride
Sounds about right after the 2nd adjustment👍
Man was I hoping that dumb carb had you walking out of there hahahaha. @endurosolo has some good vid of me bouncin off the ground goin up eagle
Send It Brother! 🏍️❤️😎
Just subscribed, like your content man! I just bought a 23 tx300 and love the thing! It definitely feels a lot different than my last bike (carb tx300) it’s a sweet machine. Been thinking about a rk tek head for it. Not necessarily for more power as it has plenty but wondering if it would help burn a little cleaner? My 23 seems to be just a little rich
It does help. It seems that the TBI bikes are all rich. My RK head helped. That and a BR7ES plug
Dood, I'm winning that trip!🤙
Yes!
I really like my kehion 36mil carb on my 2019 Tx300 but I also enjoy on my other bike my 38mil lectron carb as well I believe both carbs have there good points and bad but nothing is perfect .
punk rock club says cage match with Zach! 🤘
Yes
I vote to call the xtng carb "Carb X"!
Good idea
Need to see a review on tsp injector relocation kit on a tpi! Thank you
Coming soon!
Yo Awesome video. Love the idea of your giveaway. KEEP IT TWISTED.
Thanks
🤘 I’ll be there.
🤘🏻🤘🏻
12:00 Don't ever apologize to anybody for riding your dirtbike. You have as much right to be on that trail as they do.
Thanks.
Good time.
You have Xtng gen 3pro. (Gen 3 nonpro is external ventilated)
For info
There are two more circuit options on gen 3. The assist circuit on or off. It's a bottom end thing.
Stock is off and only gives 1.5 (1-2)turns on air. I found that 1/8 - 1/16 matters! In this mode
I know you put too many turns on On gives you 2 half turns.
Once outside of those measurement you adjust rod. Like you did (two clicks) not sure you weren't right direction.
Float hight does matter and might need adjustment. My gpx tse250 the carb is angled. I don't know if KTM is level. I don't know what adversary that has on fuel pickup. I'm not good with that knowledge set. Thinking you could lower fuel level? Maybe bouncing is releasing fuel?
At this point I would reset mix screw to middle 1.5 (1-2) or 3 (2-4) (depending on which mode you are in). Drop rod I believe.
But you said you 2 clicked richened rod? (Up, CCW). Wouldn't that worsen loading? My thinking was you leaned idle. So now reset it and drop rod (lean). So your not picking up as much fuel at velocity (rpm) and loading? Another way you leaned screw to compensate for being too rich on the needle. Now you need to lean rod and richen the idle screw.
What are your assist turns?
For now your power jet should be off.
There is almost too much going on. It is not dumbed down.
I'm still not sure which mode is better for what.
I think the loading has to do with float level. The reason I richened the rod was because it was pinging (detonating) after a long hard pull in the open when I’d shut it down. Also why I richened up the pilot. It seems just about perfect once I clean it out, just loads up in steep terrain. Talked to XTNG and have some settings I’m going to try.
Gee that’s like my 14 Berg TE300. Keihin, cy head and SX ignition. PDS is decent on it.
Hey Morgan, what kind of reeds are in Loretta - are you running vForce 4's?
Whatever the stock ones are
Id be careful on that canyon trail, at one point I think I saw some Jawa's
Hahaha
Let’s see some hill climbin out there👊👍
I'm so used to hearing bikes with fuel injection that the carbed motor really sounds sloppy compared to clean jetting of the fuel injected bikes.
It does. I can say it was better with the other carb but not as clean as the FI
I'm not sure if its the same stateside but the europen enduro ktm exc I have has a keihin 38 with notched slide. with the suzuki needle change its very good. In a range of temps and elevations with small adjustment to air screw between summer/winter.
What do you think that spark plug main difference would be ? I have the 300sx and I noticed in your video you mentioned the other plug might be better .
It’s just a little hotter plug so it will burn off extra fuel and oil and keep from fouling. Normally you fix that with jetting but since we can’t tune on these yet it’s a good choice. And my bike actually came with the 7
@@highlandcycles you should do a video on testing what two stroke mixes we might be able to run on these tbi . Have you just been running the recommended expensive stuff from ktm at 60:1? Iv always ran klotz r-50 and some other semi synthetic oils on carb bikes. I wonder how this tbi will run maybe doing r-50 at 50:1 or stretching it to 60:1. 🤷🏽♂️
@@Backyard.bandits I have been running 40:1 from the get go. I tried 60:1 for 5 gallons and the running was identical
Thank you
👍🏻
That TBI sounds angry awesome 👍
Oh yeah
I would bet money that if you put the TBI pipe on the 2019 bike that you would gain a noticeable power increase.. FI does not make more power on its own over a carb. But if the engine's Porting, Pipe, and/or Ignition Curve is different (improved upon) then either or all of these WILL add power.. My opinion is that the pipe is the main player here in the power difference between the 2. You could even just test on your road at your shop since the pipe mounts are probably different? Again.. It has been proven time and time again by MANY shops AND books, that FI offers zero power increase over a carb induction. Let's get some testing on this!!!
The FI doesn't make more power, but the motor does. Between porting, and ignition and maybe compression (I never did a compression test before or after your head but I think its higher) This motor definitely has more juice. As far as the response and power delivery the TBI kills it because they got the FI right and the E power valve is progressive now.
@@highlandcycles What I have been told from those that have looked at the engine.. the porting is the same as previous engine.. The ignition curve can definitely be a player as well.. but IMO, the pipe is where most, if not all of, the magic is coming from.. I think the viewers would like to know why it makes more power. If you can fit the TBI pipe on the TPI or Carb bike, that is an easy upgrade IF that is the major difference.. Need somebody to find out.. Know anybody willing?
Dyno sheets show 9-11 HP increase in the TPI (stock) over TBI Stock.. Less with the carb since the carb makes more power than the TPI.. But that is a big difference
The pipe is way off. Maybe with just the springs but I am not sure the silencer will go.
I don't know exactly what it is but the power is nuts on the new bike and the E power valve is brilliant.
Woooo! 🤘
Hey does anyone here know why my dirtbike rims keep cracking?? I replaced my front rim because it was cracked and now the replacement rim has a crack too! Now my rear rim has a crack in it too. It's an old bike, could it be that the rims are too old?
When you say the carb is loading up do you mean flooding too rich👍
Yes.
carb for 2strokes
tbi or tpi for 4strokes
Put the keihin on with the stic and do the comparison!!
I don’t have a Stic anymore. Never liked it as much as stock
@Highland Cycles thanks for the reply, I've had really great luck with mine paired with the RK head, If circumstances permit you should give it another chance, I can send over baseline settings too
@@maxbalogh5507 it’s long gone. Wasn’t mine anyway. My buddy who had it never liked it much either. He jetted that thing a 100 times.
I carry a set of lightweight vibram sneakers (prob 200gram?) in a fender bag on the front of my bike in case I need to jog back to the car....Good luck to anyone trying to cover 8 miles in mx boots.
That is a good idea. I just carry my inreach.
Yeah I carry tech for major emergencies. I just dont want to bother someone with a bike recovery if it's just a breakown. Just jog back to car, recover the bike and you're home without bothering anyone.. 🙂
@@Superdisco199 I like bothering my friends. Hahah actually, I’ve never broken down by myself. I’ve only ever had to be helped once when I hit a rock with my chain guide on an old YZ and it broke off and bent my rear sprocket. I’m pretty lucky and I try to get all my work done in the shop.
Hey Morgan....Question, why do you always face the sun and squint when starting videos? Seems it would only make sense NOT to stare directly into the sun....no? LMAO LMAO LMAO. Just messin'.......great, informative video as always! Love these types of comparison vids putting bike up against bike.
Do you have the SX boxes on the carb bikes
SX boxes??
@@highlandcycles the SX controller pull better off the bottom and rev out like a 250
@@randydriewer5847 Oh, you mean the computer. It has the SXS ECU
Like, comment, and subscribe! Interesting stuff, and I dont even own a KTM.. blue crew! ;)
Yeah YAMAHA!!
Wait so the carb has zero venting?
It’s internal venting like the Smart Carb
@@highlandcycles
My Smartcarb also loads up when I drop the bike, takes about a minute before you can turn on the bike. In theory the check valve should close the gas flow but in practice doesn’t happen.
Agree
Gen 3pro is internally vented external adjustable.
Regular Gen 3 is externally vented internally adjustable
KEIHIN or a TBI for me
Agree
What is daisy worth?
I sold her for 5500
@@highlandcycles when you take the cost of Loretta minus 5500 that isn't as bad. You did buy at the high point- fresh on the floor
🤘
🤘🏼🤘🏼🤘🏼
That xting sounds like chit mang..
I agree right now. I think I can make it better. I hope
🤟🏻🤟🏻
🤘🏻
Thumbnail says tpi vs carb lol. We all know the carb wins that battle.
Hahahaha, I screwed that up. I will fix
Do you think you would have shaved the 10 seconds riding the old bike another time just from familiarizing yourself with the trail? Seems a hair close to be drawing conclusions from a single data point...
Definitely not conclusive at all. Never really can be unless it’s a huge difference. Might be able to shave more but then could shave more on the new bike with another run. The biggest takeaway to me is that the TBI is amazing and the spring forks on the old bike are amazing. Probably going to swap and see how that does.
@@highlandcycles Sounds like a plan!
Dirt bike hair do ,ggg
