I just did the TRE mod this weekend and I am not really sure if i feel a difference. Most likely because the bike only has 500 miles on it and i didn't really get used to the bike the way it was from the factory. It does feel smoother, but power wise i can't really tell. It is having the hard starting problem now once and awhile. What do i gotta do to get this bike to power wheelie up in 2nd?? I am thinking of maybe throwing a sprocket in it. Next mods are going to be Slipons and an undertail.
