Re: Starter Clutch

I would like to know if I am having the symptoms of starter clutch problems. The bike turns over fine if the on/off switch is in the off position. But it stops with a violent clunk intermittently when the switch is on.

There is a long story behind this beginning with me removing the motor to change the stator. When everything was back together it would not start even though I had fire in all four cylinders. It was suggested that the pulse generator was the culprit and I took the motor out again. Found that one leg of the wiring to the PG was broken and I repaired that. My long time motorcycle mechanic inspected things. He felt that the pin behind the PG that sometimes fails was okay and agreed that the broken wire was why the bike wouldn't start.

Got the motor back in yesterday and now I have the problem explained above. At one point the bike kicked over like it was going to start, but the starter stopped again with a clunk. Does this sound like the starter clutch or something in the PG that has messed with the timing?

If it spins fine with the 'kill' switch off, I would suspect that the timing is way out. Silly question and I would guess you've checked, but have you got the coils/plug wires or PG's switched over somehow?

Not a silly question at all but I still have the numbered spark plug wires and they are in the correct place. I did not pull the plug wires out of the coils.

Also, I did not do anything with either the timing belts or valves as the bike was running fine before it stopped charging.

No prior issues with the starter.

I'm not familiar with the 1100 ignition system (I have a GL1000 with points) but it does sound like the timing is out and if you had that problem with the PG, it may have caused an issue. Can you statically check the ignition timing with a test lamp?

the alignment pin is not in place. referring to one of your prior post there is a picture which you state the motor is at T1. assuming this is true the rotor lug should only be about 10 degrees past one of the PG lugs. you can always just drop the swing arm instead of removing the motor to correct.

Best of luck !

I saw your reply on the Saunders site and I will look around for the broken piece from the crank pin.
Here is a picture of a slot at the end of the crank that I think is where that pin slides into. Motor is set to T1.





This would be the approximate position of the alignment notch once it is all back in place. That would be 90 degrees from where I had it originally. Look okay?

Yes ! That looks much better. For a more accurate "static timing" set the crank to "F1" and verify the poles are aligned. To get any better than that you will need a timing light and a sight plug for the timing port so you can check / set the timing with the engine running.

Not sure what it means to have the poles aligned. I've always had this done for me. I have a guy that was a Honda dealer mechanic and he has always installed my timing belts, synced the carbs, valve adjustments etc. But this time he missed the alignment on the pulse generator.

When the Pole / Lug on the Rotor passes the Pole on the PG the ignition system generates a spark. When timed correctly this will occur at "F1" ( "F2" for the other PG) crank position.

Excellent explanation. I haven't been able to find, or read, anything that explains how to set this. Thank you.
