I'm about to do my valve clearances on my GPz 750, which is about the only thing I have never done before. I had it in my head that it was complicated. Your video has showed me it is not.. Have done everything to the bike on my own "including engine rebuild", so not worried at all. My question is: Clearances should be between .13 mm and 0.23 mm for inlet and exhaust. When resetting the clearances what clearance should I be aiming for? Should I be aiming for a low clearance, high, or somewhere in the middle? Also, when reinstalling shims isn't it important which way the size numbering faces in the seat? Thanx!
Hi. First of all, I appreciate your videos. I have a question and maybe you can answer it. I have a Kz 650. In the manual it informs that the light of valves can oscillate between 0.08 mm and 0.18 mm. If it is within that range, it is not necessary to change the shims. This is according to a maintenance manual. Well, what I can not understand, is if it is correct to have different valve lights. I have on my motorcycle exhaust 0.15 in cylinder 1, 0.13 in cylinder 2, 0.14 in cylinder 3 and 0.12 in cylinder 4- And in admision I also have different valve lights. In admission 0.12 in cylinder, 0.13 in cylinder 2, 0.11 in cylinder 3 and 0.12 in cylinder 4. Is this correct? Will the engine work well with different lights? Or do I have to leave all the lights on, say, at 0.12? I would greatly appreciate an answer. From now, I appreciate your time and the excellent videos that youtube uploaded. Thank you. Alex.
I believe you are speaking to the valve stem/shim gap. What is important is to shim to the valve stem/shim gap within the range dictated in the service manual, which will vary from valve to valve. Note, you do not have to use the same thickness shims in all valves, in fact, you likely won't, due to the difference in valve/valve seat wear between valves. Rest assured, the shims required to maintain the gap will vary by valve, which is perfectly normal. In other words, maintaining the gap per the service specification is what is important. Thank you for your kind comments!

GPz84 yes numbers always facing downwards (from what manual and fellow mechanics have told me)
