Where do you plan on finding larger injectors? I know with my bolt on XB12R I am maxing out my injectors now at high rpm WOT. I have heard of switching to a V-Rod intake setup but I haven't found any higher flowing injectors for our XB's.
I've read that the injectors from a Cooper mini s will work, the ECM was originally designed to control boost and waist gate on the XB. The bike was originally designed to us a turbo from the factory. Buell had full emissions and durability completed until Harley killed it. At 9lbs of boost buell was getting around 135hp and the wheel.
Worse come to worse, some injector adapters would allow for more standard sizes to be retrofitted. From what it looks like the stock ecu will be able to run boost, and if it doesn't control timing a btm might work out alright for low boost on stock motors. Once I start peicing stuff together I will get he whole tuning situation knocked out.
i would be extremely interested if it was good quality bolt on kit.with injectors,fuel pump and tunning.electronicly controlled wastegate would be worth the extra money also.:)
