Am wondering about getting the 250 kit when it arrives, and would think, due to the CC, it would be a farily torquey motor.
Which exhaust pipe would suit the kit best, the more revvier one or the less revvier one,
if that makes sence.

Will probably have the gear ratio at 4.9

...I think the Fat-Mamba will to a very good job with the RB250, but you have to get the exhaust port higher....

Ive check with Andy Francis & he has said it will fit no problem as for performance well
I dont believe its been tried yet. So this engine Im doing might be the first !
Andy & I, have discussed and it should fit better !!

BSSO was it the AF exhaust on yours.

Mark what will do is if yours doesnt arrive I can use my One m8 to get you away.
