Hi all, been awhile. Anyway, I have a 1985 Tri-Z 250 that is revving up insane to the max rpm when I turn the choke on. When the choke is off it has a slightly higher than usual idle and still able to ride, but when the choke is on things get out of control with the motor. My compression is at 175 psi and so far I haven't seen any leaks anywhere on the bike. I am not sure what I am looking for next, because I was expecting an air leak? Any help would be greatly appreciated.
