Another little tidbit that I should mention (because I read the TSB at the dealer yeterday) is the software update is only for late 07 and 08 bikes that have the new engine management computer dubbed BMSK-C. These are bikes that have ASC or are capaple of having ASC using the info that Poolside posted in another thread.
My 07 bike was built in December of 06 and has the older engine management computer dubbed BMSK that is not capabe of ASC and is not covered under the service bulliton that I read over the dealers shoulder.
So long story short, even if your bike runs rough at low RPM's, the software update will do no good unless you have that newer engine managment computer.
