Hi I'm new to the forum as well and I've got a similar problem! I've got an 06 1200 r, mine also when, starting up when hot has a bit of pre ignition! I've checked the fault codes and there is'nt any and there dosn't appear to be any air leaks either! any more ideas? ps it's got se2 slip ons and dyno jet kit but no free flowing air filter yet.
Thanks
