Hi I recently brought a gv650 se and had to replace the regulator rectifier. All went well until it stop running and then would not start. I replaced the ignition coils no change tested bike stand switch ok and also tested the pick up coil and that's ok. When you switch the ignition on you can here the pump priming and and when you push the start button the engine turns but the engine does not catch at all. I also tested the Tip over sensor and that's ok to.Also has a brand new Battery and I've tested it.
