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

OK, done with the bottom end, everything but middle gear cover on (hookup hose to clutch slave cylinder), time to check the valves. Gotta pick up some feeler guages tomorrow (metric or standard?), then tomorrow night get'ter done. Huge question----- got the loaner kit from BuddyRich (Thanks KYCaveman & BuddyRich), how does the tool work? Before I screw something up, book doesn't show, all it says is to install it, then rotate the cam to remove it. Also, with timing mark on T1, lobes are laying just off to the side of the intake and exhaust valves. After measurement, do you turn the lobes up, or what? Searched for a thread on this but could not find one. Last item to do before buttoning up the motor and moving on to the frame and everything else. Thanks, Dan

hey guy's, The manual I have state's that at TDC on the compression stroke on #1 cylinder that it can be acknowledged by the cam lobe's being opposite or facing away from each other. When I achieve TDC the cam lobe's are facing each other. Am I missing something hear or has 15 years of wrenching on cage's diminished my sense's? Is there a procedure listed here somewhere or have any of you done your own valve shim check? Thank's for any info, Jake.
