hey guys, just rebuilt my 01 cr500. went out, brought it, rode it once then stripprd the whole thing down. replaced every bearing, swingarm to engine and rebored it too. my question is sholud i break it in on synthetic engine oil at the recomended ratio of 32-1 or use a cheaper oil? on four strokes your ment to use cheap oil or you can damage the engine. does the same apply to smokers? its a steel bore with a vortex piston.
