Bluesmoke250, does your bike smoke alot? As i stated in the first thread the guy i bought it from claimed he replaced the crank bearings and seals, but ive only started the bike and not run it on a track yet, it was smoking alot when i started it for 5 mins yesterday, it would clear and then smoke a little, i cant help thinking it could be crank seals, even though they have been done? Or it could just be running rich as i got a black drip/line running out of the silencer. I havnt got a manual,do you know what the standard jetting is for this bike? I got a NGKB8ES plug, main jet 180S, needle N3C1 with clhp position second from top, dhdnt take pilot jet out so dont know that one, does that jetting sound standard?
