ditch the KTM 4 potter, and get a Husaberg 6 pot, with a 310 disc, no more problems. only joking,  nice bike, I do miss my Supermoto, 650 Berg, one day I will have to get another.
 the LC4 got a good motor, and I belive responds well to a little tuning, 
 have a look at solentsupermotos.co.uk, there's afew on there with them there beasts.
 have fun.
