Ok Fellas, I'm working on an '86 with 38000 miles on it and we are checking the valve clearances. Now I have always checked for valve clearances with the lobes facing upward 180 degrees away from the valves. The manual, like everything Yamaha does, is complicated to say the least. I find when I measure it my way that all the clearances are good except the intakes on #2. How the manual states is to go by TDC and the lobes should be facing away from eachother. My issue with this is that the lobe is already starting to load up on the shim as I can't get the feeler gauge all the way through. I need some help for you boys in how you have done this and what you know...PLEASE -
I have the cam covers off, and the gaskets need replacing. I read somewhere that the gaskets from a later model (RSV?) were better than the original VR versions. Does anyone know what part is best? The valve clearances themselves are just a fraction under the minimum clearances .... maybe .01 to .02mm all round. The engine has 56k on it. That's actually not bad, especially the very even wear aspect of it so I will leave them alone for the summer and check again in the Fall. By that time I can find out which shims I'll need, and won't mind waiting for them. In the meantime it will come to no harm. Thanks.
