I Recently got my bike running its a 1988 kx 80 and in the carb i've got a 52 pilot jet(i also have a 58, and 60) incase i might need them for different altitude My Main jet is a 150 (also have a 118 on hand) and the clip on the needle is on the top, i found it runs 10x better with the clip on the top. but the Problem im having is that it puts out to much smoke and spits Oil from the Exhuast and the bike wont Idle.if i ride it around for awhile then pull the clutch in and pop it in neutral i have to rev it up really high to keep it from dieing.Specsifications are 58 pilot,155 main 32:1 pre-mix. so could anyone help please and by the way fuel lines are ok and idle screw and pilot screw dont seem to do anything to get the bike to idle So any help Would BE MOST APPRECIATED..

What elevation do you ride at?

Your jetting should be lean with those jetting specs not rich so you have another problem. I would suspect that you either have a rt hand crank seal that is leaking and the engine is sucking transmission fluid into the combustion chamber, or you have a worn out reed valve, or your motor has really low compression and needs a top end replacement. Pick yourself up a service manual and let the troubleshooting begin.... :)

Cant it be The Pre Mix i mean 32:1 is alittle to much oil and by the way if it is either the transmission leaking or the reeds are messed up, it kinda sucks because i dont have any money so i cant replaced the reeds or get the transmission checked out so any alternative solutions, although i do have a dad that knows everything about bikes and is good at repairing them. but i was wondering if this is something that we (me and him) could fix without spending to much money??

No the premix has nothing to do with it. It has good compression? How do you know this? Did you do a compression test? The reeds looked good awhile back? How about now? You have to remove them and put them up into the light too see if they are sealing. There are no alternative solutions in solving the problem. You either fix the problem or you don't , it's that simple. First you have to identify the problem. The easiest way to do this is buy a service manual and go through the troubleshooting section. You could have something really easy to fix but, it is hard to diagnos over the internet with so little of info. You could have a plugged vent tube or a plugged pilot jet which would keep the bike from idling. The smoking could be from old fuel.
Did you drain the tank and put fresh fuel and oil in? You could be spitting oil out the silencer because it needs to be repacked. Is the idle screw all the way in? Is the air screw adjusted right? (normally 1 1/2 turns out from all the way in ) There are a lot of things you can do to help track the problem down. Now go get that manual and get to work! :)
