Thanks, no engine upgrades yet... Just the exhaust, intake, and racing plug as far as performance upgrades. Trying to keep it as reliable as possible until I eventually get a v-twin Buell. I'm partial to the S1 and M2 but the XBs are awesome too. I'll keep the Blast regardless and when I don't rely on it so much I'll hopefully do some serious engine upgrades, and probably some suspension upgrades too. Donations welcome, lol.
