Re: Starter Direction GSXR 750 90 L
You do know them starter motors look the same but depending on the year of production of the Gixxer may turn in different directions as some models have additional gear in the middle and need different direction starting motor!
You said it was re-built, if You bought brush holder assy not being 31132-27A01 part number or at least with the same brushes connection which affects what way the rotor will turn that might be your problem.
Usually You connect 1 wire (+) and the body gets the earth so I don't think You connected it wrong...
I hope it may help
