Coil compatability

[freki]

I picked up a pair of Katana coils from a 2005 on e-bay. Like new with wires for $30. A lot cheaper than the aftermarkets. :-D

Thanks for that. So are the green-cap coils the only ones that will work with my GS?

So is this working on your bike? Any mods? If it's working on your bike....is something like this:

similar to the ones you have?

just wanna throw this out there....have you checked out the ignition relay thread? not sure if your coils are garbage or not, but if they still work, this might give you what you are looking for, at a cost of 10dollars, though, the new coils do sure look sexy. as does the fat spark they are supposed to throw.....

Thanks greg. Yes I've looked at the ignition relay mod and it's something I plan on doing in addition to the coils if I end up buying used OEM coils.

Does anyone have more info on the compatibility of the Katana coils?

I am reasonably sure all katana coils will work and all Bandit coils also. You can use any 3 ohm coil as long as it will physically fit the space on your bike.
Dyna greens are 3 ohm also and Accel come in 3 ohm (they're notably larger though)

Awesome. Well I just bought two 2003 Katana 750 coils of eBay so we'll see how that goes

just from my experiance this guys

i tried some 6oof (what you might call a katana ) coils on my old 750e & although they did work they got hot very quickly, i changed them for a set of correct ohm cheepo aftermarket coils & didnt have a problem, the 600 coils have now been running my mates 1200 bandit for near on 3 years no problem

make of that what you will but i guess the use of coils meant for electronic ignitions are no good for a points setup

From my understanding that would be expected if you have a points ignition and you tried using the gsxf coils (I'm assuming that's what you're talking about). Impedance on coils for a points ignition are like 5 ohms, whereas for electric it's about 3 ohms. From what I've found the ignition on my bike is electronic, and the correct impedance is 3 ohms, which is hopefully what the katana coils will be

Going a lower impedance than your system is set up for will cause things to overheat because there's less resistance to the amount of electricity running through them right? Whereas you can use coils with higher impedance without the overheating problem (but they push less than ideal power).

Hey thanks Freki that makes sense to me which is amazing as i know didly squat about electrickery

wires are full of smoke & sparks usually when i mess with them :-D
