thanks guys i tried misting the engine while idling to check for air leaks, doesnt seem to be any unless theyre in the carb. Will adjust the clip and see if that helps. Also, i was under the impression that these bikes dont idle unless the clutch is pulled, am i correct? ive been riding the thing all along this way, the bike has to run at least 8km/h otherwise it quits (unless clutch is pulled) this is normal, right? if i let go of the clutch while stationary, itd die. also this thing is pretty hard to start, i have to warm it up for about 10-20 mins and open choke to get it running nicely, also noticing the exhaust gets considerably hotter than the engine, and a bit of white smoke. what does all of this mean? Also, the crank seal is something id very much like to check, but i dont know how. also the engine is custom mounted to the bike so taking the engine apart is quite difficult for me. oh, and just to add, the spark plug is also always a singed black, but it runs, and it has crazy vibration at low rpm
