RG500 which is essentially two parallel 250 twins, makes 100 hp on a good day so 250 with even only 60 ponies seems like a great result.
Got some wheel spin exiting the corners (wet) on my bone stock R5K which I did not expect at all, loads of torque and very usable power mid-rangs, would not want to trade that for peaky 70 hp with a big hole in the middle, if I want the excitement of "Wile E. Coyote strapped to a missile" I'll just tide my RG500, there is no 3D ignition or variable RC valve, it's either ON or OFF.

Appreciate al the response!

Gonna add up some numbers and make a decision at some point, got plenty of time to mull it over
