Can I use '73 750 coils and wires on my '73 500?
« on: April 15, 2010, 11:45:45 am »
Hi guys, just wondering if anyone knows the answer to this off the top of their head.  I'm at work and don't have any time to do a search.  The Honda dealer here can get new coils for the 750, but not my 500.  On the other hand, there is a cheap parts bike that I could buy that looks to have decent coils and wires.  My wires and caps are shot so I could just replace those instead for a cheaper fix I guess.

Anyway, if anyone knows the answer, I'd appreciate it.

Thanks, Lenny.

 If you're just lookin to swap coil assemblies, the stock 750 coils may have shorter wires molded to them. I'm thinkin the coils themselves are the same, but the wires molded to the stock 500 coils are longer.

I believe they are different ohms values but will physicaly fit and work
