I did put the Yammi shims in, that was probably the largest boost I've noticed. where do you usually go riding? We have been to Bruderhiem a few times, and last weekend we went to Darwel and Lac La Nonne ( tonnes of deep skag )
Hey Perry, the copperhead unit will give you a noticeable boost in the bottom end. I also had shims put in the clutch to get engagement a little earlier, haven't had a chance to ride it with everything yet. Hopefully I have good news after tis weekend.
