its got a lot of bottem and midrange power whith the stock pipe!!! normaly i want letting make a calculated pipe on the bike by a dutch person in holland wat i now from a other forum on mine porting and stroking with dyno runs etc.. there was lot more power but not with stock pipe ( and that was already alot!!) the handmaded pipe would give more power on top an little more on bottem and midrange ,but i got a buyer who wants specialy this bike and gave me 3000euro... so i sold it on the happy new owner and dont now what he is doing with it

i rode it about 10huoers with no problems
