2003 CRF 150F valve clearances

Recommended Posts

I just got this bike.It's been rode kindaof hard.I'm going to adjust the valves.All I can find is .004" clearance intake and exhaust.Can anyone give me any advance pointers on how to adjust the valves to get optimal performance?Yes I know to get piston to TDC,both valves loose,but I have heard of rolling the engine over in top gear to a certain point.Can anyone give me any pointers?

I have the power up needle and jets ordered.

Thanks for any advise.

.004in or .010 mm

Thanks,I checked them Saturday.

I had heard the exhaust should have slightly more clearance,but I went ahead and adjusted at .004.
