My son's CRF 100 needed linkage and swing arm rebuild. I bought the Pivot Works kits that replaces the OEM plastic bushings with steel needle bearings, seals, and roller pins. The needle bearings are super tricky to install. The needles are in open races with no retainers, and want to just fall out. For the linkage I used the dust caps as guides and just pressed them in. I Still had a few needles fall out but wasn't a huge problem. The swing arm is really hard. The kit comes with 2 bearings to replace each plastic bushing. I've heated the swing arm and froze the bearing but still having a hell of a time getting them pressed in. Question 1. What are the tricks to getting these bearings pressed into the swingarm? Question 2. Why are there 4 bearing seals instead of just 2? Question 3. I think it might have been better to just buy new plastic bushings?
Romanian Tractor posted a topic in Dirt Bike Pictures & VideoClick here to see my review of the Yamaha TTR230 which I uncorked to make it more usable and more fun. Power mods come from de-restricting intake/exhaust and re-jetting the carb with 130 main & 38 pilot. Gearing mods are a lightweight rear sprocket (same size as stock, 49 teeth) and a 15-tooth front sprocket (stock it has 13). Not only were these mods only $100 or so, but they were simple to install, made a huge difference, and the bike now sounds a lot meaner.
New to Thumper and new to the '08 KLX 450r. I purchased this bike a few months ago. It was showroom condition. Took it to a very reliable mechanic that I've known for years and he said that the bike probably had less than 10 hours on it. Speedo/tach/hour meter computer no longer worked. Previous owner said he bought it from a dealer new in crate 4 years ago (hard to believe I know) and that he was the only one that rode it. Dealer was saving for himself. Probably hiding it from the IRS or something. Previous owner said he was selling it because he never rode it, parts would be hard to come buy, value was dropping because it's not available in the US anymore and he didn't won't to deal with it. If it means anything, he was in his late 50's. I also took it to a local dealer mechanic and he said the same thing my mechanic said. Based on the condition of the bike and what everyone said about it, I couldn't resist and dropped $4,000 on it. Maybe a little to high for a bike that old, but based on the condition, good reviews and how easy it is to work on, I figured it would be a reliable bike that I could trail ride on for a few years. It's a little heavy, especially carrying my fat ass around. I'm 6 ft pushing close to 300 lbs and 47. What are the basic first mods that everyone does, what mods are recommended in conjunction with other mods to get the best performance out of. Seller included a Jd jet kit just never installed it. What brand of mods is the best to get. I realize that I could search here and there through the forums, but just would like a list on one posting. Sorry about that, but thanks for your input and advise in advance.
Hey Kawi riders! Wondering what upgrades I can do to a new KX100 will give me better performance for woods riding. I would also like to know if upgrading the exhaust/muffler actually increases overall hp instead of just transferring the powerband a bit. The 2014+ models already have 28hp. Hard to believe they can draw that much hp out of 100cc! Which muffler and exhaust would you recommend KX100 woods riders? Thanks
