With gen 1 pistons and rods and gen 2 crank, you would need to run a big .100 spacer. (.08 for compression plus .02 to make up for stroke.) Plus you would need adjustable cam gears to make up for the taller deck height. The ad does say aftermarket camshafts so it’s possible. But the 309hp pull shows 16psi which is low. That’s usually 350-360hp conservatively. But the 75hp drop from 10k to 11.3 or so backs up that theory.View attachment 1601651
fuel is getting dumped in and killing the power.
I do see the blue tip on the upgraded 65lb injectors.
Yea aftermarket fuel injectors are in, and like I said 309 is a conservative tune to be able to sustain long WOT runs which a normal drag bike is incapable of doing
