2008 CRF150R; I have 7 hours on my bike and have lost a lot of power. From the talk on the TT site I imagine my valves have tightened up. My problem is that I am in Okinawa, Japan and my manual is in Japanese. I ordered an American Manual, but don't want to wait to ride. Is there a detailed "HOW TO" somewhere in this site or on the net that I can follow to adjust the valves and, what special tools do I need to buy? ie certain size feeler guages, etc. I already changed my filter and engine/tranny oil with MA 10W-40/30 if it matters.
