I'm sitting on the side of the road...

Was going just fine, 60mph down the road, when i hear this terrible clatter from the front of the bike... I think i know what it is... I stay steady on the gas, and slowly roll off the throttle in 6th gear. I let the bike coast all the way down to fast walking speed, staying on the gas a bit, then i shut it down, and it bumps to a stop.

I'm guessing i saved it, and it will probably only need a cct swap, though i'm not entirely sure...

I'll try to get it done asap, then report back

Thanks for all the threads explaining exactly what to do when the noise is heard.


On my iphone, waiting for my ride...

Well you knew in August that you were sitting on a timebomb!

Check that you don't need new valves, piston, head etc....

My posting wasn't so much in surprise, but more in humor... Cracking open the valve cover now.

Well I wouldn't worry about the piston so much but obviously you could have dinged the valves probably only the Intakes. You wouldn't have trashed the head either unless you broke the valve guides, which can be replaced but most dealerships/shops either don't know how to do it or don't want to.

In the best of all possible worlds you just need a cct (forgive me Voltaire).

If you're talking about a set screw in the side of the CCT, doesn't that still leave the spring exposed to failure? As in the worst of both worlds... a non automatic CCT that can still fail? Or are you talking about something else?

Drill & Tap = Done. I'm getting the acorn nuts welded on tomorrow. I'll have another set ready to go soon too, if someone needs them.

I reset the cam chain/gears tonight, everything now matches (they skipped a few teeth when I was turning the flywheel nut, but never opened the valves during that time because of valve spring pressure).

Gonna install the manual cam chain tensioners tomorrow night, then compression test front and rear, to see if any damage was done. It was the front spring by the way, broken like all the other pictures, just a few coils in from the end.

Praying for a speedy recovery, and good compression...

Cold Compression (with no oil added to the cylinders):
Front - 140psi
Rear - 142psi

God has blessed me.

Once again THANK YOU for all the posts telling me what to do when the CCT spring breaks... In case anyone missed it:

1) Don't pull in the clutch or shift!
2) Slowly back off the throttle until it decelerates to a walking pace then shut the engine off (with clutch still out and bike in gear)
3) Keep it upright until the bike stops

I also found a missing vacuum cap on the front carb's T.... Crazy.

Should be running tomorrow after work. I'll ride it to church tomorrow night and report back.

I still have to fine tune the MCCTs though. Just set them Finger Tight + 1/4 Turn for now.

Thats too tight. Should be just till you can feel pressure on the adjuster then back off 1/4 of a turn

Really? I thought I read that was what you do... I don't have any squeal noise or anything...

Okay, I will check it out either later tonight or tomorrow. Gonna do a 50 mile ride tomorrow night.

It started right up today

No noise or squeal or lack of power= probably fine. I wouldn't worry about it. May not hurt to check under the valve cover or tune them more, but "finger tight" is so damn vague I would hesitate to call it correct or incorrect over the internet...

I agree 7moore7... I had planned to do what Tweety suggests and adjust them while listening to the engine... Eventually I'll get to that
