def take it out of the bike. if you have a solvent tank or parts cleaner, or even access to one, it will help tremendously in cleaning all the parts and peices of ur motor. everything needs to be cleeeeaaaan clean clean when you put it back together. if you have the downloaded version of the clymers from somewhere on here, i would highly reccommend just buying the actual book. much easier to see the pics and much much more clear.
good luck!!
