This question is about my quad's motor but it just a motor question. I noticed when I let it idle it has a faint knock/engine noise coming from it. I do not hear this noise when I tap the gas at all. I also noticed if I pull the clutch in, rev it up some and let it idle with the clutch pulled in the noise is down to barely nothing (faint) but as soon as I click the shifter in nutreul, and release the clutch the noise gets abit louder. It doesn't nessecary sound like a bad noise cause another person I ride with has another LT250R and hers makes the exact same noise and runs fine. My compression feels great and starts in 1st (2nd at most) kicks. Could this be just normal engine noise or do I need to take it serious and rebuild the topend? BTW anyone know where I can find a audio sample of a engine with piston slap so I can make sure it isn't that but I'm pretty sure it isn't the piston slapping around type noise.
