ok so now i don't understand aaen has a big bore kit that bores out the cylinde to 76mm. Now thats only .157 of an inch bigger that will make my 250 into a 280. Something doen't sound rite. Check out the site for me its on the right side of the page.
Aaen

 

does this make sense to anyone, anyone. (thump! thump! thump!) IS THIS THING ON!

 

Here ya go --->

Radius of bore in mm squared -- times stroke in mm -- times pi = displacement in CC (read first 3 numbers)

School is in session , tell us what you come up with .
