2003 EC 250 opinions - Page 3

It has a 300 head, and the stock 250 ignition mapping. The EC bottom ends are the same, right fellas?

Can't comment on the comparison if anyone is wondering. The power curve seems pretty linear though - though I am thinking I might prefer the EC flywheel to the DE. The DE revs up pretty quickly in my opinion, but I'm coming off a 4 stroke.

I'm sure you mean a complete 300 top end conversion, not just the head.

Nope, just the head . . . now if I could just solve that compression issue

What??

I don't think thats possible with a stock 250 cylinder and 300 head, as the squish area fits into the cylinder. 250 bore is 66mm, 300 is 72mm.

Even if it did fit, why??

GMP - that was just a weak attempt at humor. Yes, it is a full top end. (I should have said top end, not head). Sorry for all of the confusion.

OK you got me.
