Question about Motorcycles
Not uncommon for 2 stroke mx bikes to blow black spooge out of exhuast. I suspect that your sparkplug electrode is black or dark color also and it may even be fouling plugs occasionally. This is cause by a worn or improperly adjusted float valve in the carb and or a worn needle and needle jet. The overall jetting of the bike could be too rich but you should replace any worn parts first before attempting to rejet. Also repack the muffler after repair as the packing is oilsoaked and will continue to drip .

Once u have the piston out then there is a tool you can use for extracting the rings or you can simply use strips of tin and slide it behind the rings from were the two ends of the ring meet and slide them round the piston. Be very careful when putting the new rings on because ther are quite brittle

nice bike you have there.
have you checked on the carb ans see if the jet is right and the mixture is normal, this is usually the case if the carb is not tuned right.
better of reset the card, open it clean it, then set to default even if you are using your mixture of gas and 2t. just set to factory default. once it starts give it a few run, 1-2 hours, then set it to how you want your mixture to be.
hope this helps,

On a 2 stroke bike cause of smoke is due to excess oil in the fuel oil mixture, incomplete combustion in the cylinder or the engine oil finding it way in through the piston rings into the firing chamber. Check the oil levels and clean the plugs, which must be black in color by now, so replace if possible and if engine oil is low, the change the piston rings. Also look up the carburetor jets/nozzles are clean and the engine gets the correct fuel/air mixture by adjusting both fuel and air jets(turns)...sodeep

Use 10w40 motor oil in the gear box. Don't use any synthetic oils, oil marked "EC", or oil with "special" additives. Stick with the major brands; Pennzoil, Quaker State, Mobil or Shell. If in a hot area like Texas or New Mexico go with 20w50.
Use TWO STROKE ENGINE OIL in the pump. If not using an automatic oil pump, then mix the gas and oil 32 to 1. That equals 4 ounces of TWO STROKE ENGINE OIL to one gallon of gas. NEVER use motor oil in the gas. Only two stroke engine oil.
