So am I right in thinking that a 600R CDI will work OK with my 650L wiring if I dont require electric start? My bike is push-start only bike anyway so Im very interested !! I dynoed my 675 on Friday and it cracked 52.5HP with a bit more to go, but I ran out of jets:bonk: Engine is running a HSR48 Mikuni and carburates as well as the bored out VM40 (42.5mm) Mikuni at the bottom end that I was using before. I removed the accel pump rod to start with but will refit it and use this a bit at a time to see how it goes. All the engine needs now is a good ignition system!!!
