I bought a 03 gsxr 750. The previous owner did "Special modifications" that I'm working out. I replaced the rectifier, stator, battery, fix wiring, kick stand sensor, radiator with an 05 gsxr 750. The first problem I had was the bike took a while for it to start especially when it was cold. Then I went through more of the wires and found a ground that was cut and wired back together shity. Fixed that and now the bike starts right away with out stalling once. Then it continues to stall when idling when it hit 116 degrees. I'm not sure if there's a ground somewhere that's not connected or what. Oh also when I start it the lights brighten. If anyone has any ideas I'm all eyes. Oh it rides great. No back firing or anything

Strongly suggest getting\ downloading a manual and trace all the wiring to find issue. Hard for anyone to answer the issue without being at the side of the bike. Do you have a multimeter, a must before you start.

Thank you I will and yes i have a meter but I just figured out why the bike is stalling. The tube on the air box that is suppose to suck air for combustion is blowing air. Now I'm trying to figure out why. If you have any ideas I would appreciate it very much
