I have a 2001 RC at 30k miles and checking the valve clearance. I have the heads off but I want to verify which valves are intake and which are exhaust. And just to make sure that the two heads are the same setup. I believe the intake valves are forward and the exhaust valves are in the rear of each cylinder. I only base that on the measurements i've taken. My exhaust valves clearance is about .25mm for the rear cylinder. The minimum is .28mm. The intake is within limits for the rear. I think I'll have to take off the right side cooler in order to make sure the index lines are in line with the cylinder head surface before I take measurements. Second question, since I have basically the whole bike taken apart, is there any other maintenance or tweaks I should do while its apart? Other than oil, spark plugs, air filters. Any help would be appreciated.
