Hi,
In need of some help/advice recently got back into trials bought a second hand Gas Gas 250GP 2019.
I can’t get it to run right kicks first time from cold, warms up but constantly racing like the choke is on and smoking a lot can’t get the mixture and tick over scew right it then will stall and won’t kick over again. Plugs not oiled up and running 75 ml to 5 litres
Any help would be greatly appreciated.
