Message: [QUOTE="Aaronkdx, post: 916213, member: 60923"] I can't really desribe it, it's almost as loud as the engine & exhaust(stock pipe&silencer) but it goes away when you rev it alittle. I am taking to my local shop to have them look at it tommorow? Does any one else have this problem. This kid that lives out the road and has a rm85L say his dad's 04 rm250 does the same thing. His dad says it's PISTON SLAP. He also said that those 200 Kawasaki do that. [/QUOTE]
