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.
