Great post. Just got an old '90 650 and in the process of stripping to the frame to build back. Bike runs great but I thought a complete once over would pay off in the long run.
I planned on adjusting the valves - a little noisy - and this post is just the ticket. My only problem is what is the clearance for a '90? I have not been able to come up with a manual anyplace - if anyone know of a source paper or electronic that would really be appreciated.
Thanks for any help.
