I'm obviously new to the forum but I didn't see a new member area so I decided to sign in here. I've only owned two other Yamahas (still own an "08" FZ1) but happened to spot a really nice "80" SG and decided to pop for it. I should be picking it up on Wednesday or Thursday. It has 56k on it now. The owner has done some updates such as new rubber, battery, exhaust, fork job, etc. I've ben trying to find the valve adjustment intervals but I'm having a bit of a problem finding a good schedued maintenance log. I found a recommendation somewhere that suggested every 4000 MI but that sounds pretty frequent to me. I can't remember any bike I've ever had, including six Harley's that required valve clearance checks that frequent. MY FZ1 goes 26,000 MI between checks. Anyway, this bike is a beauty and the first thing I plan on doing is removing the Windjammer faring and bags. Nice to be on the forum, hope I can add some experience and a few stories.
