If you go with the 88SE, you can upgrade to the 108SE with just the stroker crank and piston for around $400, plus the larger carb. To upgrade to the 117 SE, you would need the 54mm cylinder, the piston kit and stroker crank. To upgrade to the 124SE you'd need the 124SE crank, 54mm cylinder, piston kit, and bigger carb.



I'd go 88SE and you can always upgrade later.
