coils?

Post by Eddie »

I was wondering where you guys get your coils? I ordered the newtronics system and i wanted to replace the coils as well, im not sure if the newtronics system needs different coils or not? i think I read that it did not, but i still want to replace mine, the right cylinder doesnt seem to fire like it should and Iv replaced points, condensors, and checked timming and still seems to hit and miss? so I wanted to rule out the coil being bad, just want to know that the whole ignition system is new so I can rule this out, so where is a good place to get coils? I checked bike bandit, knk, and rusty riders so far and nothing,

I don't know about new coils, but the coil packs are identical across all the triples, and the Kokusan coils (grey plastic) are 100% interchangeable with the Denso ones (brown plastic).

They come up often on eBay, it doesn't matter if they're from a 380, 550 or 750: they all work.

Rex Caunt coils are a good choice. See this thread for more info & pics of how I mounted them on my GT750.

Website has them on sale for £13.99, or about $22.

Some older Suzukis use ~2 ohm coils. T- & GT-series bikes use ~4 ohm coils. Make sure you get the right ones.

3.7 or 4.4 ohm is fine.

The Rex Caunt coils have 80mm mounting point spacing which fit the Suzuki coil brackets.
Don't know about the other coils you found.
