Break-in is the act of seating the piston to the sleeve.... A wear in process.... modding the ports on the sleeve in no way at all alter the "fit" if the p/s.

If anything you could richen the needles 4 or 5 hrs and work back to the new sweet spot since youve totally changed the tune of the motor

yep ur right....i ran the motor the other day and found that since i modded the sleeve the tune was ways off line.
what i got out of simple sleeve mod was...
better fuel economy...bout 5mins more per tank
smoother power delivery/better response

and without being on a dyno im guessin that i got a cople k rpm out of it....it seems like it has lot more.
still havent found much on block and crank but my buddy just toasted a nova rossi, so he's gonna give me his crank to see if i can duplicate the spiral cuts in there. he's called it, "turbo...something or other".

ill let u guys know what happens
