I'm not sure, but I seem to remember that they don't usually do anything smaller than 600cc bikes, now I could be wrong but searching round the net has brought up a few firms that do "remapping" but all seem to be for large bikes, your best bet is to give a few folks a call that do remapping and see what they say, it might be that someone does do your bike, sort of off road type thing, but they may be as rare as rocking horse shit. Someone on here might have a better idea on what's out there, wish you luck tho and if you do get it done please chuck it up on here as others will no doubt find it interesting.
