[QUOTE="dirt bike dave, post: 1410296, member: 18302"] Well, no way removing the lid on the airbox is the equivalent of leaning out the main jet by 10. Opening up the exhaust likely had a bigger impact. Does your bike have the side barrels and top KIPS valve like the '91 US model, or only the top KIPS valve? Maybe the SR is noted for no top end... never seen one in the USA. Besides jetting, things that contribute to fouled plugs are: Weak spark Bad plug Too cold a heat range on the spark plug Restricted intake or exhaust Air filter oiled too heavy Fuel leaking into the cylinder from carb [/QUOTE]
Verification
