too low? hmmm, not something i thought about tbh. im guessing that top speed is about mid 20s mph with the 11t if that helps. it is still running on the rich side tho, just to keep the throttle in check, it gets a bit bloody lively... tuned right id say 30 is realistic with the 11t

too low wouldnt damage the clutch bell bearings tho would it? remember the gen spurs are 43/39, which are only 1t off the ct4s spurs, and of course the bigger & heavier wheels. the clutch was warm tho, nothing like as hot as the cen one got, which was on some other (cheap) bearings with no bearing probs running 11 and 14t 1st gear.

i will try the 12t first tho, see how it goes.

amazingly the diffs are fine rolland, not a mark on them. they are the optional heavy duty ones. maybe they are made from the same stuff as the genesis spurs... i can get pics if u like! i was expecting them to die straight away too mate. i even have a spare hd set here!
