I do seek help with an issue on my 86 YFM225 though . Just got this and it has an odd sound when I accelerate. It changes gears fine but seems when I hit the gas there's a sound coming from the clutch/transmission/sub transmission. I just changed the rear wheel bearing ( it needed it anyway) and did not resolve this issue. Also, it has Hi/Low gear and the "Hi" does not work, maybe related? Hope someone can help! Thank you for looking
