my valves are making a taping sound and i lost a lot of power and need to know will lose valves make me lose power so can someone tell me what they are seat on thanks
although okorder / You don't want to go opening up this motor without one. I've done alot of motor work on my bikes, and still use one when I open them up. How long have you had this quad? Is it a noise that recently started? How many hours on the bike? or has it been like this since you've owned it? Typically, these high performance motors inherently are noisy anyway....so it very well could be normal. If not normal, the noise you are hearing could be a variety of different causes, as there are many moving parts. Timing chain, timing chain tensioner, valves, valve springs, piston slap, rod bearings can all cause tapping and knocking noises. So, unfortunately, there's no easy answer to your question.
