i have a ct 265pv that has ct mx porting...now i haven't rode it yet, so i'm not sure how the power is, but i like alot of low and mid... to be honest, i like the power of a mx ported lt250r...if that helps. is it possible, if i need reporting, to get this kind of power from that cylinder? i'm running it with a sparks mx pipe.

Yes it can be re-ported.
Some cylinders are just a bit more work than others, say like a cylinder with nikisal bore.
If it has nikisal bore, then to properly port the cylinder the plating needs removing, do the port change & then re-plate the bore.
A sleeved cylinder, its just a matter of doing the re-port, champhering the port edegs & go.

Normally turn around would be 2-3 weeks for a re-port & bore & fit a new piston, but realy depends on work load at the time you send it.
Carbs, you choose that depending on what track conditions your running on. Long open tracks, big bore carbs, - tight short tracks, small bore.
A 39mms not to big for a 265, my daughters 265 had a 42mm
