with the power of a 650 being delivered at low revs,it did not need a 5 speed box.they have enough torque low down not to need it.the 750s needed 5 gears as power was developed higher up the rev range.it was also added just because the japanese did it.
i think you will find that in an acceleration race,with having an extra change,the 5 speed will slow you down.
best improvement is to change the 19 tooth chain sprocket to a 20 tooth....cheers :hammer: :hammer:
Now,where did that bit fall off ?
