I can see there you would get 1.7. "Total Amount" is very misleading. Thanks for the link BTW. I lost that manual 20 years ago. I looked through some of you're earlier posts. Going by the condition/milage of that bike. I would be VERY surprised if you had any real issues. The fact that it starts easily, and has new boots tells me that the PO (or mechanic) likely already adjusted the Pilot screw and generally knew what they were doing. In response to your post regarding the noise from the top end, it's likely normal valve clatter. Mine had a lot of top end noise when it was new. I wouldn't worry about that either. It doesn't have enough miles to have a stretched timing chain, and the Auto cam chain tensioner should also be fine for the same reason.
