I actually wrote him and sent the procom seller the link to this particular thread. I thought he should know the results of his preproduction ECU'S.

So everyone should contact them!!!

Funny - I haven't gotten a reply to the email I sent to inform him of my results.

So- this morning I went out, and just on the off chance, tried Belle. She started right up, but was ticking.

Test ride (all 100 feet of it) gave me a tenative diagnosis - I think she jumped time. Badly. I suspect the ticking may be a valve just barely touching a piston.

The buying a car thing took all day, so I haven't done anything else, but the first order of business this weekend is going to be verifying the timing and getting a bore scope into the cylinders to check for piston damage and bent valves.

If the cam chain has slipped a tooth, it's fairly rare, but there have been some failures of the cam chain tensioner.

It tends to be at a point when the throttle is snapped back from high rpm & the tensioner ratchet fails to hold as a reverse torque is transmitted thru' the chain. For their D675 racing kits, Triumph provide a replacement simple screw & locknut tensioner, as there had been failures with the ratchet on those.

Couple of old threads have some info:

Merlyn,
Sorry to hear about your troubles. I hope you repairs don't cost too much. If you do end up swapping to 955 internals I'll see if I can get you a list of what you'll need from the head mechanic at the dealership here in Fargo. He's done the swap before so he might have some good info.

I believe these engines are NOT interference design, so I doubt that a valve is touching a piston. I might be wrong about the non interference design.

Besides the coils that Mike mentioned, I can tell you that a loose nut on the headers can cause a very annoying ticking sound and it is hard to diagnose the first time it happens.

You, Sir are now officially my bloody HERO.

I'd love to have that information. If this little mishap doesn't force a rebuild, I'm going to do an "unnecessary" one as soon as i can afford it anyway. I've been drooling over the idea of a 955 Thunderbird since I found out such a thing was possible. Cause, you know, Belle Mort isn't lethally fast enough as it is. Who wants to settle for a mere 135 mph? :: laugh ::

I never made any firm claims to sanity.

It is certainly possible that the failure happening right after fitting the ECU was a coincidance. Stranger things have happened - just not this week.

Hopefully I'll get some hard answers this weekend- it's all conjecture and guessing until I start pulling things off.

The reason for the jumped time theory was that on that little test ride, she ran smooth enough, just felt like she was dragging an anchor. Exactly like a car that's far enough out of time to lose power, but a degree or two shy of running rough. I've never had it happen on a bike, but I'd had a couple of cars do it. it's usually in that damn annoying spot where adjusting the distributer isn't quite enough, and rotating plug wires is too much. Or maybe that's just my luck :: chuckle :: And the tick is coming from the top end, but it's too "solid" sounding and loud to make me think valve adjustment / lifter issue. And it wasn't there before the bike died, and was when I got her re-started. Gotta be related. I suppose there's an outside chance she busted a lifter... in which case I owe the guy on ebay an apology.

I'll start digging Saturday. I am picking up a scope tomorrow (cheaper than a head gasket), and might even pull her into my spare bedroom and start tomorrow night. Yep- the joys of being single and living alone :: laugh ::

Stay tuned!
Merlyn

keep us updated. I'm still interested in the ECU's if it is discovered to be innocent in your problems.
