Before I head off in all directions....
OK, recent aquired a 93 xr250r. Starts and runs out pretty good. My concern is "White Smoke" very strong at idle once the bike is well warmed up. I am to old to be interested in Peak preformance, but if I need to get some top end work before thing deteriorate, where do I start.
So, should I suspect rings, maybe valves? might the just need an adjustment or could they be warn-out?
What would I spend for a complet top rebuild/ Do I need to include new cam and timing chain? Remember, the bike is running OK.
So, What say you? I'm not much of a mechanic but willing to get my hands dirty.
Thanks in advance for any help, suggestions, advise.
