Smokin bike??????

Hello I have an XR650L and smokes at startup....alot.... and is burning one qt. of oil for one tank of gas. I was wondering if its the rings or the valves seal?????? or maybe a hole in the piston??? any ideals ... thanks

When a motor smokes at start up that usually points to valve seals. Doing a leak down test where you can listen to the intake and exhaust ports,(crankcase also), will answer your question.

If you're burning that much oil, the top end is shot.
