[QUOTE="bhendron, post: 1170306, member: 73554"] Pants, I Did my CCT last year and just checked my valve clearances this weekend. However, I tried to get by with generic o-rings on the coolant pipe and quickly discoverd a coolant leak around the pipe upon start-up. Bike was fine apart from that. This 'how-to' was very helpful: [URL="https://www.fjr1300.info/howto/valveadj.html"]https://www.fjr1300.info/howto/valveadj.html[/URL] The factory service manual was so vauge... However, the method described in above link IS a bit different in at least one aspect. The author says to check clearances simply by rotating cam lobes on the cyclinder being measured just so they are 180 degrees from the block (pointing straight up). The FSM instructs you to start with cyclinder one at TDC (timing mark on crank shaft lined-up with the mark under the timing cover.

Mine were, thank goodness. So that 's as far as I took it. This was my first time performing this proceedure on any bike, so take heart, it can be done. I welcom any comments or corrections to what I stated above. As I said, my first time. [/QUOTE]
