Hi folks, I'm a newbie to the site from the UK and a newbie in the land of Kawasaki Heavy Industries! I hope I can contribute to the site in the future and would be grateful if I could draw on your massive collective motorcycling knowledge!
I've got hold of a cheap ZX7R (20,000 miles on clock) and am a bit concerned as bike has not been cared for - I've got bills for the first crucial services but nothing for valve clearance checks - I took the head off last night and measured the clearances - three valves appear out of clearance - the valve that is most out of clearance is out by 0.04mm (intake valve measuring 0.13mm - tolerance range is 0.17mm - 0.25mm). Don't know if a valve this out of clearance has done damage or not? - I guess I'll have to do a compression test after reshimming to check for valve sealing issues?
Thanks in advance for any advice. Kind regards, Sid.
