Hi first post . need help

I'm working on a crashed kz750 spectre its a 1983 model
and I need the pulsing coil and advancer and the bolt that holds it on they were all crushed in the wreck.

anyway the question is will a coil and advancer from a 81 model work if not does anyone know where I can find the parts?

any help would be greatly welcomed

I have the impression that those parts are the same for all the small four cylinders, 550-650-750, that use electronic ignition. The advancer weights may be different tho, to control the advance. but I think if you stay with a 750 you are good to go.

On my '83 750 LTD shaft, (Same as your Spectre, basically) I am rebuilding the same things from a crash. I grabbed a 750 advancer off ebay, and the pulsing coils too. I didn't really pay attention to what year it was, it should work.

On my 650 I am using 550 pulsing coils and a 750 advancer cam/lobe on the original 650 advancer. The 650 runs smooth now.

For the 550/650/700/750 4-cyl, there are two types of electronic ignition. One is a mechanical-advance type, andthe other is electronic advance. The parts don't interchange between the two systems. The 83 Spectre uses the mechanical-advance type.

The electronic advance type system can't be installed (without modification) on (some or all?) of the older engines due to a clearance problem in the motor casting.

However, the older type can usualy fit into a newer engine. Normally you wouldn't do that unless you were short on cash or time, or something.

Thanks for the replies the parts I'm biding on ebay right now don't match the broke parts I have 100 percent
but they look close the only diferince I can see is on the coil the magnets or what I think are magnets are covered in plastic the advancer looks just like the one I have.

sorry if thats not a very clear description

whats too much to pay for these parts and would the dealer have them?
