So while I have all these thoughts of upgrades running through my head, the next concern would be the throttle body and injectors. If the heads come off, I'll get some port work, and will add 107 pistons, cams in the 240 to 246 duration area. Not looking to get extreme numbers, but a good running touring bike. At what point does one need to make an upgrade of the injectors and or throttle body. Will a stock throttle body handle a 105 to 110 hp motor? My guess it would need at least bigger injectors.

As always thanks for the help
