Today I show you the installation of the Steahly Offroad 12oz fly wheel weight on the 2000 Honda CR250R project bike we’ve been working on. The hope is that this medication will give the bike more traction by slowing the motor down a bit. It’s also possible that it will give the bike a bit more low end torque, but I don’t know that for certain. It should be really interesting once we get to ride the bike again.

Honda CR 250 03-07 Flywheel Weight For reduced stalling and a smoother, more controlled and tractable power delivery use a Steahly flywheel weight. Most riders will ride better and longer with our flywheels, just like Ryan Hughes did with his win at the inaugural Las Vegas Enduro Cross. The 2003 to 2007 CR flywheel weights that add 6, 8, and 10 ounces are very easy to install. The installation of the 12 ounce is a little more involved because you must grind down a small flange on the inside of the ignition cover. The 6, 8, and 10 ounce need no modifications. A Dyno test by Dirtrider Downunder Magazine on a 07 CR 250 showed an increase of 1.13 horse power at top end and an increase of 3.67 HP / 2.09 ft-lbs of torque at low-mid range.
Here are links some of the products that I’ve been using recently on the channel. The Amazon links are easy to identify, but the other links are for Rocky Mountain ATV/MC… even though they don’t look like it until you click on them. Thank you for using these links. It’s one of the ways that I’m supporting my family now.

Being a mechanic myself, I switched from the red silicone to the permatex Grey, it really holds up better than the high temp
absolutely either use grey or honda bond. I like grey permatex because its a little easier to remove at next service but holds up way better than red/black and doesnt look messy either.
Brilliant Kyle!!! I love the fact that you are taking the subscribers suggestions and affecting the changes to to Honda. This is the best build vid on RUclips ever!!! Wish that subscribers outside the U.S. could stand a chance of winning such a dream machine!! Best channel every keep the vids comming please
The 12t cs will make it rev out even quicker and lessen the flywheel effect. Why not try it with stock gearing and see if the FW can tap into the grunt? Changing two things at once always leaves you guessing.
Awesome video and bike project. You never need that much gasket maker. Thankfully, that isn't an internal engine gasket.
Thanks for posting this video!
Great video I’ve been looking on here for a while about a flywheel wieght review thanks Kyle
Nice video. Looking forward for the test!
Hey KB. Long time subscriber here, and KTM 500 exc owner. Recently picked up a nice 01 CR250. Have torn it down and rebuilt pretty much everything. Have also been thinking of a FWW...and probably going w a 12oz. Love ur vids bud. Have also recently started my own garage YT Channel up here in Canada. Builds, maintenance etc. Keep rippin out the great vids, Kyle...cheers...Dan.

I have a 97 cr250 got it bone stock put some v force reeds in it and did a 12 oz weight as well also I went up too a 52 tooth in the back kept the front sprocket stock and its truly amazing in the woods and tight single track the flywheel weight gave it so much more mid range power as well as helped with the stalling. But the biggest mod you can do with these CR’s is the carb I swapped out the pos carb that came with the bike and got a keihin pwk air Striker. No fouling no black premix everywhere bike runs clean and mean
Kyle's bike has a lectron, and a fmf gnarly pipe on it all ready
What would really make a great is a PWK air striker and pulse injection. Or add pulse injection with the Lectron Then you would get the low-end power you’re looking for and crazy over rev. No stalling. And best of all, All around improve power in all stages of RPM
10oz FWW tranformed my '06 - good vid m8
I have a 98 cr250r and I’m used to four strokes and I’m torn between 10,12 or 14oz any recommendations
@@dawkinschmidt7053 did you find any info?
I got a 12 oz one for my 00cr125 most important mod I had a 13/55 gear ratio and it still didn’t have enough low end for me so after I put that on now I can pop wheelies over logs easy and do everything gave me so much low end that I can go back to my stock gearing and might be able to go a little bit lower on the rear I highly recommend this for any mx bikes going to the woods
Love the video. I restored a 2000 CR 250R it was a blast. The fly wheel will make a world of difference in the woods, also I felt the brakes sucked on my CR and went with a Galfer oversized brake kit for my bike, worked Great. Also found a Magura hydraulic clutch system on eBay for cheep. The bike is a blast to ride. I do not race anymore, but I take this old girl out every Sunday and ride with my old buddies. Most of my buddies have bought old 2 strokes and brought them back to life. Again love the videos.
And the first thing I think of is cheap. Hyde clutch is a nice touch. Defa good upgrade.
Loving the vids Kyle! I was wondering whether you'll be getting your hands on a CRF250RX now that they've finally updated their range? It would be great to see a review and comparison to KTM and Huskys offerings. Keep up with the awesome content!
Just getting back into all this picked up a new yz250 just finished putting in frontand back springs going with one of these flywheels I think seem to be the answer
Your going to love it.
Awesome video, very interested to see what you think of the FW weight.
I noticed at 8:35 a 1/2 inch section of the bike was not spotlessly clean... I'm awed by how clean the bikes are. After one ride, from the show room, none of my bikes ever scrub up that clean. Even with the G/f's tooth brush and cotton buds.
Hi Kyle i do the same project flywheel weight and nitro mousse and think you are going to enjoy it more than a ktm
What year is the CR250 there?
I once owned 1996 and 1999 CR 250s and they actually had pretty good bottom end torque. I installed fly wheels on them, and also tossed the aluminum clutch plates and installed steel plates. That kept the transmission oil cleaner longer.
Hi love your stuff. Ive just bought a cr 250 2002 to build for a 24hour race in August im doing in the solo expert class. I havent rode or owned a bike in 18 months so it should be interesting! Do you think the fly wheel weight will work with a trail tech stator? Cheers Danny
What about lock tite on the flywheel threads, and the allen screws on the outer flywheel.
try a throttle tamer along with the weight and gearing, impressive difference on 2017 ktm250sx
How did the fly wheel weight help and the front sprocket? I’m thinking of doing it to my 97 cr250r
I don’t think the gasket maker was necessary because there isn’t oil on flywheel side of the motor. Great video. My YZ250 has a flywheel weight and it makes a world of difference.
Keeps dirt/mud/water out....but go ahead, dont use it and then you can bitch when the internals get eatin to shit by having dirt and rust in there on moving metal parts.
Also it's an old school requirement from back in the days where point ignition systems would fail from just a single piece of debris finding it's way into the point gap.
The Kriptoker haven’t used it on that side of the motor and it’s perfectly clean. So...
@@Kriptoker my uncles a professional service technician whose been working on engines his whole life and always says gaskets are overrated. its all personal preference. you can literally make one out of an empty beer box
How much weight did you put on...I was thinking about doing the same...
I want your Honda! is a nice bike!
I should be in the market for a new bike soon I'm thinking either a ktm 300 xcw tpi or yz 250 x but I've heard stories of the tpi bikes seizing at 20 hours
I’m extremely interested in seeing the video of how it performs after this. I just may do this to my 91 cr250r. I do desert and trail riding and the bike is awesome. Just not meant for trails. I hope this gives it much more low end torque.
cut or sand ur head down i do this but i went to the max now it hits hard super low and its harder to ride but dont go takeing 30 th off maybe 10 /15 th be good but it will still will rev fast and fast down low with the head mod its not like what he is doing that will slow it down but i i know alot of newer mx bike some are made for top end so a good head realy helps them idk bout a 91 but my 98 didnt need that much i going to get a think gasket to chill it out ,maybe lowing ur gearing will help
No take 30 off your Cyl base. Then fix the head. Take your CYL and Head off and send it to Eric Gorr. Tell him what you were trying to do and it’ll make your bike night and day Different
awesome video,so you mean to say that i dont really need a new gasket and just use red gasket maker right?thank you...
You should have got a hydraulic clutch cable mod on her.i use a honda cr250 1998 stock mx bike for 2hr enduro racing and using a cable clutch for two hrs gets you real`y fit.love your vid`s kyle.all the best from dep pipes davey from the uk land of the best enduro riders.becozz we learn on cable clutch power`d honda cr`s.hydraulic stands for wimps.
when are you going to test the bike?
Do u know if with the 10 oz weight u will still need to shave the stator cover
Even with the spacer you still had to grind down the cover??
Is the a large cover out there that would work??
What about the four allen set screws around the flywheel weight ? I heard from one of the manufacturers NOT to use locktite on them but didn't notice anything in the video. Just curious as to how you went about that part of the install. Thanks for the video !
For the low budget folks, put the bike in fifth gear and use an impact gun to remove the nut. Someone can sit on the bike and hold the brake if required Then use a rope to run down the cylinder hole to hold the engine from spinning when you torque it down. No special tools required.
When is the review coming out?
hi please that the flywheel weight just gets there? or is it still somehow fixed around the perimeter?
You still had to grid the cover even with the spacer?? How about if you used a Hinson or boyseen cover??
does a 12 tooth front sprocket wear the chain prematurely ?
Please revalve the forks your self thru racetech im trying to learn shim stacks and what stack does what meaning thickness and whats the diffrence in a enduro shim stack compared to other specialized shim stacks . If any one knows of a video or website that in detail teaches the diffrence i would love to know where to find this info. Thankyou dirtbike channel for all the great information you share.
Seth Jeffreys pretty sure racetech has some older videos that explain all about it and how they work
It would be cool to see this vs your buddies yz 250x
agree
Now how do you tdc the bike on 4t
Can’t wait for the first test run report! Thinking of doing the same thing to my 04. Would a 10 oz weight make the cover fit with out grinding?
I don't think it adds any low end. It's purpose is to slow the revs down and create traction.
10 oz whieght needs the grinding also. I know I have a 10 oz and it's the perfect whieght. 14 oz is too heavy and anything less then 10 oz is not really noticeable. In my opinion.
@@scottgaskill4896 at least in my case it helps a ton gives me a tad more low end so I can pop the clutch over logs something I didn’t think my little 125 could do
Hey Kyle. Would you trade me my desert tank off of my 05 for that stocker?
This will make this engine be completely different.
Bought one of these bikes back in 2007 for enduro riding (2006 model) but never really liked the bike. Found it too revy, no torque and suspension too hard. I guess the bike was more suited to mx riding. Still have the bike though.
Maybe now is the time to sort out the bike. Any suggestions to make it more enduro friendly.
Do the mods!!! My '06 is a woods weapon...... FWW - Keihin carb - head and cylinder mods - crf250x suspension f & r and 13/48 gearing , you will be amazed at how these mods changed the bike for bush riding.
@@graememoffat4533 Thanks for the suggestions. The crf250x suspension is a good one!
@@diarmuidoc9427 I like 13 50 gearing more for woods and 13 48 for MX but each their own!
@@jakewaggoner4196 Probably depends whether one is going like a scalded cat along forestry roads or up to their axles in mud doing more slow technical stuff through the woods.
The thing with that UHMW plastic spacer is nothing adheres to it. Probably better off getting two gaskets or making two rubber or fiber gaskets. The company I used to work for got the idea to CNC small UHMW electrical enclosures as a way to save money vs the stainless steel enclosures they were using. At first they tried to use silicone on the mating surfaces, that failed so they machined an o-ring groove but the plastic cover deflected enough to allow water in. The company ended up replacing all the enclosures with stainless enclosures and replacing all the damaged electronics inside plus the labor for me to change them out. If you pull on the dried silicone it will practically fall off the plastic so it probably makes no difference using the sealant.
How was the bike after?
One thing at a time
Whats with the extra red gasket? There's nothing to leak at that side 👍🏼
So nothing can get in
I think these mods will change the bike for the better.
where can i buy fly whell weight? does someone send the store link?
Rocky Mountain atvmc where I got mine for my 00cr125
Should of got the msr flywheel weight for it
For the first two minutes I’m sitting here thinking he does realize like the whole point of a fly wheel weight is to add low end torque 😂
I just might have to do this to my kdx.
KDX 200 or 250? They come with a heavier flywheel to begin with right?
@@casmitherz1988 kdx 200.
Kdx doesn't need anything.
Maybe a fresh piston and rings if it's never been done. Boyeson reeds, updated handle bars, larger foot pegs, new air filter... After that just stiffer springs for your weight. You should be good to go for not much money.
Why do woods bikes have 18inch wheels?
For a taller tire sidewall.
Steahly recommends checking the flywheel tightness every 8 hours of riding which seems excessive
What does a flywheel do exactly to the bike?
It does what is stated in about five comments above yours it does exactly that it’s been said probably at least five times. Read
The flywheel is for spark timing.
Just rebuilt an 01cr250 today goddamn yz250 are easier to work on and engineered way better
Leave the flywheel weight in the package and keep the bike as a wide open desert bike. 😁
I have a 2007 CR250R and I don’t see how this will make a difference. Just 1lb when the mother is spinning so fast anyway. I believe it’s just all in your head.
That’s because you haven’t done it. So yes it is definitely in your head . But everybody is entitled to an opinion and you know what they say about those
Ps. Your poor mom she must be dizzy is As can be.
Do you have for the CR 125? Does anything improve on the CR 125?
Yes I have a 00 it went on smooth and I highly recommend it made the bike so much better in the woods honestly if I didn’t put that on I’d want to get a different bike only thing it does now is the power band is a bit more mellow and doesn’t pull as hard when your revving it out the weight works so good that I still have the stock 13/52 on my bike and it does great in the woods
Wouldn't this extra weight cause the motor to be unbalanced? Seems like it would wear parts faster and possibly destroy an engine from the inside out.
LoL.
Use a magnet!
So you took a 15 year old 2 stroke MX bike, tried to build it for trails, then after a year put a flywheel weight on it?
No. That is not at all what the video is about.
U could always buy a used cover....
Personally dislike flywheel weights, I honestly don't get why so many people rave about them. If the bike is too aggressive change the gearing. I found the bike really difficult to rev up and come on the pipe, if you need the power down quickly for a big hill it becomes a big problem almost feeling like the bike is jetted wrong with a big flat spot. Anybody else feel the same? Or just me 😂
The red shit on the gasket was useless...
Never ever use gasket maker. looks like shit. Always just use oem gasket.
looks horrible doesn't it lol never use crap like that... id always use an OEM gasket or at the very least cut one out of gasket paper myself.
pasta roja vaya chapuza .....joder negra o gris .....
Not worth it. No grunt. Been there.
Messing around with stuff I did in 1998. Lol.
Good luck.
You are making a big mess, that will never clean off. It's not even hi temp over there. Beg, beg for your old job back please, tell him you didn't mean to call him a Jew-Kike, por favor.
How did the flywheel feel??
