600cc upgrade for BLAST ?
Hi All. New to the site. I've been running a Blast as second fiddle to my Panhead bobber. What I'd like to know is has anyone upped the BLAST to a 600cc ? If so, can this be acheived by simpy using barrel and piston from a XB12 ? or an XL1200 ? Mine is a 2000 model Blast, any info welcomed.
