trialssport Posted July 26, 2016 Report Share Posted July 26, 2016 After a shocking ride at a recent 2 day trial i have decided to try and get the TY sorted ! The problem is the engine takes ages to rev up its very very flat at top end ,if i hold the throttle wide open and let it rev its nuts off it seems to clear itself after about 10 seconds but then runs crap straight after .Bottom end power seems really good and loads of torque Things i have done so far 1) Stripped carb cleaned out and replaced little o'ring on main jet. 2) Replaced main seals on crank 3) Tried altering ignition timing 4) Altered main jet height for less fuel (plug was black) Any help with this problem would be very appreciated !!
