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 .

SOURCE: i have a1987 kawasaki kx 250. it is very hard to kick

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

hi murray,

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,

regards,

voodoo

SOURCE: engine problems on a kx 250 2 stroke

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

SOURCE: i need to know what weight oil to use in my 03

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.

A “very helpful” rating for this answer? Thanks!

Whats the best 2 stroke oil to use on a 2005 kx 250


Everyone will tell you the oil they use is the best, so you are going to get a different answer from everyone that answers. I've been using BelRay MC1 for over 35 years and I have never had a lubrication related failure. I am still proudly racing 2-strokes at the top amatuer level. I have heard good stuff about Amsoil but I don't use their premix. I do use their suspension and brake fluids, though.

I suggest using BelRay MC1 at at least 32:1.

I hope this helped.

I have a kx 250 2004 and i can ride it for about 10 min and the engine seizes up on me what could be the problem?


im presuming its a two stroke it sounds like the two stroke oil pump-which is starving the engine of oil-change the pump before u destroy the engine-this is not a maybee,your engine will need a total rebuild if u carry on riding with this problem!!!!!!!!!!!!!

Oil leaks up by the exaust


Check the cam cover, see if the bolts are all in their places and at the right tension (tightness)

If none of the bolts are missing, replace the cam cover gasket.

A KX 250 is a 2-Stroke therefore it gets its oil by the gas/oil mixture.
