cuts out

[bob griff]

hi my ts125 with a 150 head and barrel starts and runs really well ,it will run on half throttle at 45/50 mph no probs but as soon as i apply full throttle it just cuts out and come to a stop after 2 mins it will restart a runs great,exhaust is clear carb is clean new points and condenser on ,it only ever does it in top gear,any ideas...? regards bob

Have you checked the float level in the carb? May be suffering from fuel starvation. Also have a look at the vent hole in the tank filler cap.

fuel starvation is my first guess

check the hose and petcock
one of my bmw bikes had a problem and it was sorted to the cork in the fuelcock
was clogging up the fuelcock when it was open not allowing good flow
