do i or don't i? that is the question

[ghorton3]

just install leo slip-ons on my 08 busa. do i need to have her dyno'd?

[Busatroop]

a dyno will only tell yea what power its making and the a/f readings, I think the question you meant to ask is do you need it tuned and for a slip on its not necessarily required but I’m a firm believer in a re-tune on anything I own since the factory tunes on cars/bikes are usually conservative to say the least.

Not really needed, at anything less than WOT, the system will self adjust to keep the mixtures right.... enjoy the slip-ons

I have Yosh R-22 slip-ons on mine and I'm going with a power comander due to the engine "missing and popping" at lower RPM's, like cruising through town in 2nd. The PC should smoothen it all out.

Post if you see the F1 light blink with your slip ons...won't hurt anything but some slip on's (especially carbon due to heat transfer) seem to lean just a bit more than stock and may cause your light to blink. A power commander will eliminate this. (but again, doesn't go far enough out of wack to hurt anything).
