Hello - sorry if I ask the same old questions here but I'm new to the Yam XZ550. I got a project started - engine out and now unstuck and was wondering what all I should go after and fix now. For example, I hear the starter clutch bolts always come loose so I'm thinking of fixing that now - should I do it now or wait for the chance that it might not need it. Carbs - I think I will just stick with the 82 model, etc. Thanks DAve
do the starter clutch bolt fix & tighten both balancer shaft nuts, even if they don't seem loose. they will be. bend all the tabs doew, (you'll see when you get in there)
also, this is a perfect time to do a valve adjustment.
