I have cbr600rr cool sticks on my zxr and wonder if anyone has experienced any issues with them as I have developed a misfire from 5k and something apears to be breaking down about 12k with no more power being made after that, I have replaced the ignition box with a m spec and built a complete loom for the bike, any advice would be great, thanks.

Try putting the old coils back in and see if your problems persist.

If not then at least you've isolated the problem to the coils.

Good idea, that was my next move, just out of interest what other cool sticks do people use?
