    I have an 06 450 and I was riding it yesturday and the clutch seemed fine but on the way back it Quit engaging. I started it up this morning and it was back to engaging but won’t now after a little ride. The previous owner said he had new plates installed with heavier springs
  2. Mystery fluid leak

    I just put a new clutch sprocket and chain on my 2013 yfz450 and I didn’t torque the 30mm nut down good enough bc it came loose while riding. I then noticed that under my clutch sprocket it was leaking a fluid and I don’t think it’s oil? Does anyone know what I may have done to cause this leak...
  3. Clutch sprocket nut stuck!!

    I’m trying to replace my clutch sprocket on my 2013 yfz450 and I can’t get the 30mm nut loose. I’ve tried an air impact and a large wrench. This thing won’t break loose!!!! Please help bc I’m going crazy.
