thanks mate...will take a look at the pics.
didn't think my gears were that long though. only going from memory but i thought 1st was 70-75, 2nd 120-130, 3rd 180ish and i never revved out 4th to know.
Edit:
just looked up what the std gearset is good for @ 8,000 rpm...
1st = 73
2nd = 122
3rd = 181
4th = 236
5th = 313
Looks like whatever i've got is standard ratio or very close to it....so what could it be?
