weird i made two answers and none of them stayed attached,never mind anyway the problem is your rollers are too heavy in the variator i think,i would put some 5 gram rollers in it as the problem is the transmission is in an upgeared state when you have this flat running problem due to the engine not being able to rev to create enough back pressure in the exhaust to make the 2 stroke engine work properly.i am betting you have a race exhaust on it ?let me know
