She's still a virgin, never cracked the cases or popped the jug off. I've decided to do the top-end before spring hits, but I'm not sure what all I need. I'd imagine a gasket kit, and a top-end kit. Is that it? Do they make top-end kits? Where is the best place to purchase and what brand? I primarily ride WFO in the woods, but like to get out on the track occasionally. Do they offer anything to make this beast a 280cc or so? If so, does it require a bigger carb or CDI change, etc.? Thanks!!!
