Even though I have two bikes with PC's fitted I wouldn't buy one now unless it's cheap,my K1200 which has dubious fuelling at best has needed sorting for a long time,this last week has been a 9.9 on the Richter scale because aftermarket fuelling is changing!!! the days of bolt on fuelling mods are on the way out,the difficulty for me was beleaving it, which I didn't a week ago,it's been a shock to say the least.
