Topic: What late model coils are 5ohm/12 volt with replaceable wires?

[B.O.X.N.I.F.E.]

Before I beheded my 550's top end I was checking for spark, and before I could get the boot off the plug I got a shock. I checked my plug wires and found a couple small cracks. Plug wires on older 550's aren't replaceable (without a lot of surgery), so I as wondering...

What is the best candidate for replacement coils? I know they need to be 5 ohm & 12 volt. I'm guessing early 80's 750's would be good, but I wanted to check and make sure there's no resistors to remove or anything like that.

dyna makes a 5 ohm coil

Grind away some of the Bakelite and you can get those wires out. There's a picture sequence of it somewhere... I was going to make one for the FAQs but I have Dyna coils so I've been lazy about it.

Wouldn't you want DUAL output coils?

[B.O.X.N.I.F.E.]

Yeah, I saw dyna made them. I'm more interested in the ease of plug wire changes than performance upgrade. And even some of the performance minded guys were recommending GL1000 coils instead of the dyna ones as a cheap alternative, although I think some of those were 9v/ 3-ish something ohm's which wouldn't work on the 550.

Anyone know for sure that early 80's 750 coils are 12v/5ohm? No resistor? They're on eBay for 20$ all day long, which is in my budget.

Good catch, thanks

i actually am in the middle of making my "old" 5 ohm cb750 coils into having replaceable wires were you interested?? all i've got is yellow accell 8mm spiral core wires though and they are 150ohms per foot (about half of a regular wire) and tey have GREAT Suppresion..

$20 and thier yours... they are stock cb750 coils i'm making them with the above mentioned accell wires...

the second pic is of my GL1000 coils with the same yellow wires...

I am running coils from an early 80s VF750 on my K0 750. They are 3 ohm.

Well just got a response to some eBay units I was watching... '80 750C units are 3 ohm.

Were any of the 750 coils 5 ohm?

Found It, I new I saved this info somewhere for my own use as well

look at my post a few up    i said you could have MY 5ohm coils for a price... thier from a Cb750 and like i said if you dont mind YELLOW wires or if you just want me to leave them blank...(you add your own wires) then i can do that...

Thanks for the above link, sorrry, I thought the original post implied I was looking for replaceable plugs. I have good 550 coils if I want to do the epoxy method, I was eyeballing 750 coils because I thought they had replaceable plugs, but it looks like the ones with replaceable wires are 3 ohm. Thanks though.
