CRF230F to CRF230R Flywheel Lightening, Advanced Timing Keyway, and ways to Losing 20 pounds. 

A soft Penny, perfect! I should’ve thought of that, next time.

As long as it’s at, and remains at TDC or BDC. Otherwise you could possibly bend a valve?

@@lowbuckgarage1 You put it to top dead centre, you feed enough rope in to fill the top of the cylinder head so the piston doesn't go right up, there's plenty of space for the valves to open and not hit anything, I've used this way for 40 years and never had any problems. I love all the mod you have done to the bike, I used to race a Honda XL185 back in the 90's, great times, loved the bike.

@@esmeben Ingenious method! I’ll have try it next time.

Soon!

The carb install vid is almost complete.

Careful! Good luck let me know.

@@shockadellick You’re right, In hindsight I now see that the 150R flywheel is the easier/cheaper route to go. At the time I wasn’t sure if the 150s actually would work, and I hoped the machine shop would take 16+ ounces off mine - they didn’t - only 13. Now, about those forks…

Thanks More fuel but lighter, that is interesting. Knowing exactly how much fuel is left would be useful too, hmmm🤔

I think Paul here has me beat in the trick department. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-8iagnU6k3co.html

Your right, probably the better way to go. although I did like the idea of using my original, no worries about fitment or balance issues that way. Thanks for watchin

Wow really? I soak the hell out of mine with maxima air filter oil and never seem to have problems. I do think Twin-Air is a better filter though, they were out of stock at the time.

@@lowbuckgarage1 yeah the foam isn't as dense as it should be oem or twin air is the way to go.

I was careful and reused mine, but it’s not recommended. Mine didn’t leak. Thanks for watchin’!

Hey Amigo! Thanks. Yes I see a lot of Brazilians racing these 230 machines down there. Not many racing them here. We are jealous too of all the aftermarket parts and shops available for you there! I’ll be competing with my 240cc again at Vet world championships 11/5/22 at Glen Helen National Raceway with better engine and CRF150R forks and race shock this time. I see I am already subscribed to Alemeo#66, great channel. We love Brazil!

@@lowbuckgarage1 Boa sorte amigo 🙏🏻

Great! I’ll check out your channel.

Took it Glen Helen, raced in World Vet Championships, mid-pack finishes both days. Check it out: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-lwyaWG9hq_Y.html

Of course we all know a solid axle will always be stronger than a hollow one, but so are solid handlebars, and you don’t see many of those around. I did do some research beforehand, and depending on the type of torsional forces. A hollow axle, when drilled 33%, like we did, loses less than 10% of its strength yet loses 1/3 of its weight. For a solid axle of diameter 9.5 mm (radius 4.75)the strngth is 4.75^4 / 4.75 = 107 for the same axle with a 5mm axial hole the strength is (4.75^4 - 2.5^4)/4.75 = 99 the strength is reduced by only 7.5% In regards to the flywheel, I used the original flywheel so there really wasn’t any need to use lapping compound to match tapers because it didn’t change. And you’re right, the key doesn’t keep it in place, it only aligns the flywheel for timing. Proper torque is all that’s needed in this case but it is critical. Thanks for watching.

@@lowbuckgarage1 Good to see some due diligence. However, your math does not hold true across the full spectrum of steel alloys and 5he various heat treatment processes. My son and I have a couple of 230's for play bikes. His friends often come over to rip around our extensive property. The bikes get treated as you might expect young lads to treat them with some rather hard knocks. I've replaced two bent, front axles. While the materials these bikes are made from is certainly up to the task of handling a lot of abuse, it is not premium quality.

I wish you could give me a little help improving my 2016 230. I also live in California. thank you

Made my own aluminum mounts, purchased CRF250x brackets on eBay cheap. Almost done! It’s tedious work using a jig saw, grinding wheel and dremel but it can be done. I’ll be posting that video too. Thanks for watchin

Thanks! I covered that topic in this video: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-o5ovHodBLck.htmlsi=LfXwp2MJxm3ldOWF

I was only able to find one single source, you’ll have to contact them directly. Hope this helps. www.ebay.com/usr/caydencycle?mkevt=1&mkcid=1&mkrid=711-53200-19255-0&campid=5337464679&customid=&toolid=10001

I believe 68mm is the absolute max bore, after that, you have to resleeve cylinder and bore the cases. I believe they can then be taken to 270cc after that. Pretty pricey.

From a shop called Cayden Cycle. They had them on EBay. That’s the only source I found. You might also try looking on the “Thumpertalk” website for more info or sources. Possible to make your own but pretty tricky.

@@lowbuckgarage1 okay thank you

thanks. Planning on getting cam from Web. What is 1059?

@@lowbuckgarage1 that's a good deal... Hope everything great 👍

Not sure what you mean. What gear?

@@lowbuckgarage1 Sorry my english. The starting gear you mention in video, that you make these holes.

@Italeao oh yes, my machinist friend said the starter gear shaft was an extremely hard steel, very difficult to drill without breaking it. I don’t recommend it.
