gsx 250 coils

[ukjules]

Does anyone know if the coils for a 1980 gsx 250
Allow the ht lead to come off ?

I simply cannot tell if you can ?
Is it sealed inside or can you like every other
Coil pull / unscrew the cable from coil ?

If they are anything like the coils on my 1980 450, the ht leads are epoxied in to the coils. But, there are a few threads on here showing how people have successfully used dental picks, etc. to chip away the epoxy and remove the wires so they can be replaced.

I could yank them real hard and see but i think they are as you describe and set in there.
What a sh*&e design.

Never bought aftermarket coils but if the frame connections are 80cm center to center
is it easy to find some ?

My tests however showed:
LH and Rh coil:
Prim 4.2 ohms
Secondary 11000 ohms without plug 19000 with the plug on

plug caps 5000 ohms (new)

If you think you need to replace them, any single lead coil with the primary between 3.0 and 4.5
ohms will suit. I like Kawasaki 400/500 twin coils - and the leads screw in to those...

Thanks - sounds mad but i am so bad at electrics generally i didn't know this basic stuff.

Can i just double check something on coils.

When testing with a multi meter:

Primary coil - i have never had a bad one and is usually for mine 3.5 - 5 ohms with the lowest setting on all my bikes
Secondary coil - >> using a 2000 setting on my multi meter if you get "1" they are dead !
(On my gsx i get 10000 ohms)

Would you agree ?
I only ask as i am trying to get some coils for another bike and keep getting sent dead ones !
i.e. when i test they show "1" on secondary.
