I am a newbee here, and i just got my bike home. When i started it, it was fairly quiet. I shut bike off and then when i started it back up,, there was a lot of noise in the top end. The noise was mainly in the lifter area and some up top. When started, it made a lot of noise in the lifter area and kind of made less noise. I am new to these evo motors and wanted to know if there is problems with the oil pump or anything else i should do. I do not have to be faced with a rebuild right off. thank for any help you can give me.
