152 rear-wheel HP on a RC51 with only these mods?
I'm throwing down the BULLSH!T flag on that one.
1. Blueprinting/balancing a motor refers to matching compoent parts (pistons, rods, crank etc) from a weight standpoint to both eliminate weight and reduce vibration. I suppose you could have weighed the injectors but since they are not moving parts I don't see that being a huge improvement.
2. Port/polish a throttle body? I fell out of my chair laughing at that one.
3. How do you shave/deck the heads on a bike with gear driven cams?
4. BMC filters actually reduce HP on the RC51 over the stock filters as do the short stack mod.
5. Finally there is no way you are going to get more than 140 HP out of a RC51 without replacing the pistons (to up compression) and stage 2 cams and valve guides (increase lift and duration).
