electronic ignition on sohc cb 750
hondacb750:
hi i just ordred a DYNA electronic ignition to get rid of the old points and 2 new Dyna ignition coils with 3ohm primary , i was wondering if i need to go for different plugs and if it will run to hot, any help is greatly appreciated thancks
JonnyB:
I don't think the engine will run much hotter the new ignition and coils will be more efficient, and burn more of the fuel in the chamber. I've not heard of anyone needing to change plug grade.

I agree with John.
The Dyna kit will make it easier to start and run more efficiently - I've never heard of anyone having to swap plugs.

thanx appreciate the help i just got it all together started right up but it still willl not run on all four cylinders and i have spark and compression and the carbs are super clean doesnt really make sense have to dig deeper lol
SteveD CB500K0:
Is it intermittant on 3 cylinders or all the time? If you have fuel (plugs are wet?) then it could be a plug or cap that's breaking down under the new (higher) voltages.
