ive got a problem in my 1995 300ex motor. it started when i went riding one weekend and the whole weekend it was fine.but the day after i took a quick ride and i noticed alot of power gone and motor was making a ping ping noise the whole time i ride it. when i let it sit for a week then ride it its quicker but not near what it used to be. it always makes the noise every time i ride it now. can anyone help me

 

First is the quad stock? Second what gas are you running in it? Third How does your plug look? Fourth does it during normal running, at WOT, of pretty much all the time? Fith check out your air filter, what kind of shap is that in?

 

my 300ex has supertrapp exhuast and a k&n airfilter. it make the noise all the time no matter what and my airfilter is almost brand new. i run 87 octane in it

 

do you ever clean your air filter, and how long ago also could need timing chain adjustment and valves

 

Even in a stock motor I wouldn't run anything less than 93 octane. But if it does it at idle I wouldn't think the fuel is causing the prob. Have you ever adjusted the valves. does it sound like a ping caused by bad gas or like something loose in the motor.

 

i clean my airfilter after every long ride or every couple short rides. the gas is always good in it. and it sounds like something is loose in the motor. i adjusted the valves when the noise first started but did nothing.

 

anyone help me please?
