I’m having a issue with a 2002 gsxr 750 that won’t turn over and killed on me while riding. I’ve replaced the battery, starter solenoid, and starter. The battery checks out good 12.6-12.7. But the starter reads 8-10volts when I hit the start button the starter doesn’t turn over the bike it just whines and sounds seized up/ teeth are good. The motor turns over just fine at the crank case if I turn the motor over a few times I can get the bike to turn over and fire up but right when I let off on the gas it dies on me. Put it in dealer mode I just got c00 the tps was off so I got that readjusted -c00. what can cause this issue for the bike to not want to turn over on the starter. I’ve also jumped 12v to the starter and it still didn’t want to turn? Also if I do get it to start it runs good besides having to give her some gas if rpms go to low she dies sometimes I can get it to start again but if I can’t I have to turn the crank again?
