I recently had daughters (my) bike rebored from 230 to 250. I warmed it up numerous times in the garage and turned it off according to instructions. Took it out for an hour today and I kid you not, it felt slow and sluggish just like the 230. I could not feel ANY difference and the bike was making a strange noise from the piston or the valves. My question, I have a compression tester that you hook to the where the spark plug goes and the reading was around 110 psi give or take 5. I cannot find anywhere what the reading is supposed to be for either a stock 230 or 230 with 249cc kit. Is it common to have either the piston ring (s) go out or the valves making noise after about 2 hours of ride time. I swear it had more torque than it does now and I cannot even get it to pop a wheelie in 1st gear. I have all the other mods, pipe, jetting,airbox, bbr rev box, 420 chain etc....... I have spared no expense and frankly should have just bought a 250, LOL:bonk: Opinions?
