Hi have a problem when the bike starts from cold with choke on its fine, when engine gets warm rides ok but when get to junction it stutters and cuts out, but will start straight away, then when you give a high rev it cuts out when releasing the throttle, then resarts first time again and ticks over nicly, what can the issue be cutting out at junctions, please help

1/ Give the carb a good clean out with clean petrol.
2/ Raise the Jet needle by 1 groove at a time and road test.
3/ Fit an iridium plug and make sure the HT lead is secure in the coil.
4/ Put some redline fuel sytem cleaner in your petrol.
5/ Fit a new air filter.
6/ Make sure there are no vacuum leaks.
If all or any of the above don't solve the problem let us know.

David.

on the 125cc bikes learn how to drain the float bowl

you need to find the drain screw on the left side of Carb at the bottom
lean bike on its right side against a pole ,fence or wall and open screw
and let some run out
do make sure that the drain tube is installed and not kinked

the gas where i live is so bad i carry a proper screw driver to do this all the time

lot of the time i have the problem is when i fill the tank
and it stirs up the reserve side of the tank
or have went on reserve
i have a large filter on mine and the bad stuff just seems to go right on through it
