I have this bike that I got in a trade. When I start it and run it it blows white smoke out the exhaust bad. Are these bikes known for this problem? I was told that it sounds like coolant is getting into the cylinders. I plan on taking the engine out of the bike and making it a winter project. Is there anything that I need to look for with this engine. I have never rebuilt one of these and I have no idea if anyone makes a rebuild kit or not? I would love any help that anyone can give me on this problem.
