@calum I will try that indeed but there is one fact thats bothering me: when i got it from the start, i did a testrun before buying it and idling when giving throttle in neutral was a bit off(buuhhh sound) but fixable and the acceleration was like it is supposed to, this was with the stock jetting btw. Only thing i did was rearranging the throttle cable because it revved when steering to the right. Cleaned the air filter and oiled it again with some twin air spray. Switched the backside of the carburator because the airscrew hole was messed up beyon repair and Reassembled it airtight with no leaks. Took off the spacer on the intake. And fixed the cables and aligned the ypvs correct. So as it is now, it should be like it was from the start when it worked good. Only thing that is not stoch is the romeu upper exhaust.
