Im bored with my stock shee, and im ready for a major power increase. Im debating between a vitos 404 big bore kit, or a 4mm stroker motor, bored .040 over. Both setups would be accompianed by porting, pipes, after market clutch and either bored carbs or 34mm carbs, and a cool head running 20 cc domes. How big of a power increase vs. price do you think i could get out of these choices? What would you choose? I'm really in a perdicament and we start this week. So any tips/comments are greatly appreciated! -Alex
