I may be the first to have a manual came chain tensioner fail. I must not of torqued the front cct mounting bolts down properly since it let loose at a stop light.

Now what are the chances of the valves and head being OK since it died at idle and not at speed or have I munched the head either way.

Thanks in advance.

Well munching the head is a bit extreme. Most you may have done is kissed the valves on the piston, especially if at idle. All that means is it probably didn't take out the guides but still may/did bend the valves.

What failed on the manual cct? Haven't heard of a failure.

You are not the first, did you hear any knocking noise before it died??

you are not the first, don't feel bad...I doubt I was the first either....I forgot the locktite on the MCCT lock nut when I did a valve adjustment...then I ignored the obvious tapping I heard when I was riding on the highway, it let loose coming off an exit ramp when I tried to idle

CCT didn't fail directly it sounds like the mounting bolts loosened up

There is someone selling some heads in classifieds. Heads aren't too costly for our bikes. That would be worse case scenario. Well not worse case but from what it sounds like Doubt you smashed the piston too hard.

Yeah the mounting bolts backed out since I didn't loctite them and didn't torque them properly. I had stopped at a light and the idle slowed down to about 600rpm and then it started knocking and died.

Just got it retimed and back together and it taps and needs full choke and some throttle just to idle. Shut it off a couple seconds later, guess I bent the valves.

Sounds like the valves.... the bike was running on one cylinder, one cylinder cannot keep compression, there for the chock you needed just to keep it idle.

Man sorry to hear that. Same thing happened to mine 3 days after I bought it. But on mine it was the a-hole that sold me the bike that didn't get them tight.

Should have checked the valve clearance when you timed it. If it had a lot of clearance that would have showed you if the valves were bent or not.

I hope it's not to bad!
