Need help from engine experts on cam shaft binding

Not positive on the procedure for the 550's but I believe that you set the cam timing without the tensioner, and then install/adjust the tensioner after the camshafts are bolted down.

Here's a pic. Can't see the markings, but you can see position of cams.

EDIT:.. sorry, pic too big and won't down load.

That was the first way I tried it. When it didn't work, I thought I did it wrong so I put the tensioner in. I'll take it out tonight and check it again.

Perhaps could edit pic size and re-post.

I use MS Paint program to re-size, but there are many other good re-sizing programs also readily available.

Am meanwhile looking for loudhvx's KZ550 site which has excellent advice about cam installation.

Good Fortune!

Here's another try on the pic.

Could the tach drive gear be binding on the exhaust cam? I'm grasping at straws here. In any case, just pull the tach drive gear to rule that out.

I didn't have the tack gear in at that time. Good try though!

Great links, Patton, thanks. I did see one thing that looks suspect. There was an error, according to your link, that showed in the Clymer manual where the mark should be at pin 1 but is on pin 0 instead on the exhaust cam. Is that enough to not allow it to turn more than half a crank? But it turns fine in the opposite direction, so why is that you think?

Another angle.

Darn, forgot to resize it.

Can't resize with what I got on my work computer, so it's in the link.
