Oh mate i know about a tiny bit of throttle, i can get it in the air with less than quarter throttle, it's just i let it drop, then i open it again.

As i said, it's ******* two stroke ownership lol, was the only way to stop my piece of **** gilera stalling at 12 lol!

Thanks for the advice though, i might fit one just to see if i go past quarter throttle

 

mine moves about 5mm

 

Bloody hell!
Your the don!
