Trigger wheel selection for GSXR 750..

My stock trigger set up is this:



Will this work or will a 36-1 trigger perform better?
I'm going fuel and ignition with COP's

That won't work with the standard B&G code OR the Extra code, although there is an unofficial patch that allows the Extra code to use that wheel with a special filter circuit. That said, the stock wheel isn't the best for EFI; if you have the ability to swap in a 36-1 wheel, that's probably your best bet.

Note that the B&G code only allows 2 ignition channels; if you want true COP, you need to switch to the Extra firmware.

Edit - Actually, depending on the OD of your wheel and the maximum effective width of the tooth tip, you might want to go with a 24-2 or 12-3 wheel; the extra-large gap also helps with the speed changes during cranking with a high-compression engine.

I wont be using 'true' COP but wasted spark using stick coils and a Bosch 211 Ignition module.

I've got a 36-1 trigger wheel I can modify to fit, approx 50mm in diameter and around 5mm wide

Heres mine, works really well with the gsxr VR sensor.
