I have a 2001 SP1. I purchased this a couple months ago. I have replaced the fuel pressure regulator, fork seals, it came with a power commander that had a really piss poor custom map in which has since been removed from the bike completely and a whole list of other goodies. It’s running much stronger than when I got it but when I take off from a stop, the bike seems to want to sputter and and almost stall. Once I’m moving, there is no issue with it. I haven’t replaced the plugs but I have them (NGK Iridium plugs of course) and they are next on my list. Can anyone tell me what may be causing this issue?
