If you already have good 1300 cyls on your ski just get the porting done and raise your compression by cutting head. The cost of boring and replating plus new pistons adds up. Oh yeah, if you have not done it get the vf3 reeds.

Guys, if I can respectively suggest, questions like this can easily be addressed on the forum. I don't think we should be referring simple questions like this to Lowell.
Lowell is swamped with work and his health has been a bit of a problem lately.
Yes if you have work that needs to be done please call Lowell.
If it is questions like this the forum can provide a wealth of expertise to draw on.

fastkas, just depends on how much money and/or time you want to throw at it all at once. My first jump was to port the 1300. HUGE wakeup! ski will run 79+ in the heat. Funny thing about adrenaline, it soon takes more to do the job. I'm now ready to big bore, but still a little unsure as of HOW BIG to go.

When porting is it just the cylinders are getting worked on? what else is it need to be done?
