HWB Posted September 29, 2022 Posted September 29, 2022 Gsxr 1100... starter motor works perfectly when bike is cold. Once it warms up and you come to turn on it wont work. It makes a turning sound like ita turning all by itself and not engaging rhe flywheel. What could cause this, ive been left starnded twice already Quote
wraith Posted September 29, 2022 Posted September 29, 2022 Is the starter clutch starting to slip when worm, has the bolt came undone ? Quote
Gixer1460 Posted September 29, 2022 Posted September 29, 2022 GSXR starter clutches are fairly reliable (when compared to those fitted on GSX AC bikes LOL) they either work or don't! The sprag rollers could be worn or the springs have lost tension which could be worst when hot as oil would be thinner? If the bolt had come undone, its really obvious and it wouldn't turn hot OR cold! I've never tried taking one apart and spare internals (if even available new back in the day, will be rare now) could be fitted, although whole unit replacement with a good used unit is generally cheaper option.

HWB Posted September 29, 2022 Author Posted September 29, 2022 The issue only started after engine rebuild, i used the bolt of the flywheel to install degree wheel. Only after that did the issue appear Quote
george 1100 Posted September 29, 2022 Posted September 29, 2022 Sounds like your bolt is loose. I had a similar issue a while back. Probably wasn't torqued sufficiently or correctly or both Quote

Probably wasn't torqued sufficiently or correctly or both I have to admit mine caused issues after its build but was due to a low battery so the starter kicked back and loosened the bolt, I knew it wasn't worn as it had less than 4k miles use. It was a bastard to cure, finally used some diamond / carborundum grit infused paste to lock the bolt to the starter without having to stand on the torque wrench LOL! Quote
bluedog59 Posted September 29, 2022 Posted September 29, 2022 Check the bolt torque section in your manual. The restricted model sold in Europe only required the bolt to be tightened to the German spec "guddentite" while the full power version required the higher British Standard "VFT". 2 Quote
bluedog59 Posted September 30, 2022 Posted September 30, 2022 I'd slip a fork tube over that breaker bar just to be on the safe side. 1 Quote
