@redneckjared baffles reduce noise and cut back air flow. a baffle wouldnt ruin your seals. hondas are junk personaly the only good sport quad they ever made was the 250r. the 400s are junk they are very low tech and are out dated competley.

@redneckjared okay what ever my dads just been working at the yamaha shop since he was 20 (FUCK YAMAHA) but i had a 400ex and the guy took the baffle out of it and it burnt up my valves and my seals and it was sucking hot air back in my motor which forced it back through the intake. But i do agree that if you have bad oil rings that it will do that

@oSHOLLIVERo im really not trying to argue with u ive been working on and modding quads for years i know how they work beleve me and you said oil in the ar box thats only i your rings are screwed or your over revved it or flipped it so you really dont know what your talking about

@redneckjared YOUR SOO GOD DAMMED STUPID!! VOTE THIS UP IF YOU KNOW FOR A FACT THAT BAFFLE SUCKS COOL AIR

@oSHOLLIVERo ur an idiot the baffle keeps cool air out because that will screw up the valve seats and that noise is the cam chain

@triplestompd my EX sounds like that too. but it got worse (louder) after a buddy took it for a ride (against my will) and pinned it in first gear. now there's a clack or slap noise. SMH....

your valves are getting destroyed because your baffle sucks cool air back into the motor and with out the baffle there is no cool air, i bet if you look in your air box there is oil

it may be your timing chain or tentioner, or it may be the little spring that is attched to your rods
