... I think I will buy a NOS chain and link on E-bay. Along with the front chain guide...
You don't have to pull the engine apart to check the valve timing, it can be done with a dial indicator. Pull the gas tank off(makes things handier) and the intake/exhaust tappet covers on the left cylinder. Mount the dial indicator so it touches the top of the intake valve spring keeper(valve closed) and zero the dial reading. Turn the engine forward, the dial will move as the valve opens and closes, stop at the TDC mark on the exhaust stroke. The valve will be opened slightly, write down the reading on the dial. Move the dial indicator to the exhaust side and repeat. If the cam timing is correct, both readings should be the same(or very nearly so). Sounds like a lot of work but it actually takes no more time that adjusting the valves. You can pick up a cheap dial indicator and a magnetic base for it at a place like Harbor Freight for less than the cost of one hour's shop time.Hi bike in the shop pulling top half to line the chain back up. Wondering if the shop should replace the chain and does it have to be a endless chain? Anything else you would do while they have the engine pulled?
