Next step now it's up and running correctly is to fit a 115 main jet , ditch the standard air filter for k&n type that's about all you can do to these 125 single 4 strokes , I once did this to a cg 125 made it much more rideable with more get up and go off the mark ,

Almost definitely due to carb diaphragm split, I serviced my latest purchase , bought a new inlet manifold as bike was running too weak ( no mixture adjusting screw on mikuni carb ) scratched my head a little , bike was flat out at 55 mph , fresh plug new oil and air/fuel filter no change , stripped carb , found replacement diaphragm for £10 instant power increase to 70 mph on the flat
