I know the BK mod is free, so thats were I'm leaning, but does the Factory R&D part limit time of squirt as well as the amount of fuel?
I might bring my bike to work tomorrow (machine shop) to do the BK mod. Just curious if there were any opinions out ther yet?
Thank you all, for making my life (WR) better, and faster!! :D :) :D

BK is free and adjustable. P38 is neither. As far as I've heard a stack of washers would do the same, that would be free / sort of adjustable.

Do you have something against saving some $$?

The BK mod and the P-38 do the same thing but in different ways. By reducing the duration of the squirt you are also reducing the amount (volume) of fuel squirted from the accel pump. This results in less fuel being squirted into the engine.
