Hi everyone I'm no mechanic so I'm clueless. I have a aprilia mx 125 and I got it cheap because it needed a little work like plastics and other bits. i started it with no cleaning and it smoked it's back side off and run like shit so I drained the petrol and put fresh in with pre mix of oil. New spark plug. Air filter is nice and clean. Nearly got it going with the kick start but didn't so had to bump it. Once running it don't smoke it's ass off that much now but still running crap ish. Would I need to mess about with the idle screw to get it running better?
