I have a 03 rev 600 that blew cause the water pump died and it overheated. so put a comple new top end in. Cleaned the carbs, didnt change the jetting or any carb settings. Now its running lean, plugs are white, barely any tan colour. Tried playing the the oil pump adjustment and even added lots of oil to the gas, didnt help. Any suggestions will be appreciated. also I think the copression is fairly low for a new top end. It has about 400km on the new top end and no change.
