shims?? 're-new' and 'new valves'

Dooden All that work is going to settle out fairly soon.. if running fine give it a 1000~2000 miles and at least check clearance. 5. new valves Posted by: "Ian Francisco" ocpianoman@... ocpianoman I was burned in a similar fashion . . . The only real way to know the valves clearances are where you want them is to measure them yourself. . . You have no way of knowing if the shop can't tell you. I'd ask to speak with the mechanic, maybe he can tell you. Dooden, Ian, and All . . Thanks for the speedy answers and advice. The entire situation is extremely strange. What started as a simple tire change and loosening of the c/s nut wound up as a several month odyssey and a complete {above the cases} engine & carb rebuild !! Since the carb came off first, the most obvious cause of the 'lack of power' was found - a torn diaphragm. Rather then STOP and ADVISE they continued to disassemble the engine. Without taking {or simply NOT RECORDING further measurements . . . they specified 'BORING OUT the cylinder to 1st over-size, and REPLACING the PISTON, RINGS, and {all four}VALVES. While I was waiting for the boss to return from vacation so we could discuss options . . . they went ahead and DID the work !! Bottom line: I never authorized anything beyond 'check & report', the boss agreed and all the work was GRATIS. Now that I have the bike back, I intend to keep it for a LONG time! While I know I have to 're-seat' the rings like a new bike, the valve {& shim} wear pattern is unknown. {YES - I did ask SPECIFICALLY what the finished measurements were - the only answer I could get was 'Within Spec'. therefore - NO DATA POINT. While I agree the 'money-is-no-object' answer is to disassemble the head again & take measurements, that's NOT me!! Second 'recommendation' is do it at 500 miles {+/-} - then AGAIN at about 2,000 miles. This isn't cheap, especially if it's not necessary until the mileage builds up a bit more. {bike is a 2003 and only has about 7,500 miles} All I need is some 'real life' experiences with replacement valves, some place to start. NOTE - the bike NEVER had ANY symptoms in the first place !!
