on a stock set up with 11x36!? thats nutz, I run 10-36/32 on my kitted V1's, there is no way in hell I could handle that gear ratio with out all the mods on my motor
also your doing it wrong having someone else build your bikes, your doing it even more wrong second guessing his knowledge, when you yourself cant rebuild the motor.
but at least its Richard building them, and he knows what he's doing
