91 kx 250 blows smoke and drips alot of unburnt oil out the pipe

91 kx 250 Blows a fair amount of smoke out the pipe and drips a fair amount of unburnt oil out of the pipe connection. I am running 50:1 mix and it still does it. also it uses gas very quickly and fouls at least 1 plug per ridding day. It starts very easy and idles perfect, but often when you crank it it seems to have something holding it back.

Does it have a stock pipe,carb,any modifications! If its stock,I would put a new ring and piston in it,it seems like your getting a lot of blowby,also make sure your air filter is clean. It would help if you used an iridium spark plug.

When my bike is running I get white smoke from the right side exhaust and the right side also blows harder than the left. What could this be?


IF you are running stock pipes (not "True Duals"), the right pipe exhaust ALL from the front cylinder, and SOME of the rear, and the left pipe only blows SOME of the rear alone.

The stock rear pipe splits, some going to the left pipe by itself, and the rest going to the right pipe WITH the exhaust from the front cylinder.

Now, white smoke usually indicates moisture.
Being a (non-VRod) Harley, that eliminates the liquid coolant, because there is none.

Next up that comes to mind is condensation.
BUT, this would burn off fairly quickly.

So is the white smoke only at first, or even when warmed up?
And if warmed up, is it actually coming OUT of the pipes, or OFF the pipes (like some oil burning)?

Hi, I have a husky tc 250 2010 and blows smoke from a hose coming down the frame at front of motor,i think its connected to the head? its the larger of the two hoses. what does this usually mean?


if its a 4 stroke and its the breather pipe then your getting pressure build up , what colour is the smoke , white or blue ? white is water and blue is oil ! water could be a seal or gasket leak , oil could be valve seals or stems or compression leak !

Flames shooting out of the exhaust. repacked exhaust, adjusted the floats, still have same issues


check you timing could be slightly out and firing too late igniting unburnt fuel in the silencer pipes .

1995 yamaha blows more exhaust on the left side than the right


Assuming the bike idles smoothly and is not smoking you can pretty well rule out bad valves and piston rings. If the air filter is clean then intake should be okay. Are the valves set properly? Is the decompression lever and valve working properly? I assume there is not mud plugging up the pipe. That pretty much leaves the muffler on the right side having an internal collapse and is restricting the flow of exhaust gases. Remove the mufflers and see if the pressures are equal at the head. If the problem is still there then have the shop do a compression check. It is possible a ring has broken or is frozen in the ring groove. This would let some compression into the gear box and account for the lower exhaust pressure. I hope this helps.

My blaster 200 is blowing alot of white smoke


I agree, Too much oil in the mix. I run at 40:1 at the moment but have also used 50:1 in the past with no problems.
Drain the fuel tank and re-fill with fresh 40:1 mix.
Tip the bike over on its side to run out the carb.

Good Luck.

2002 rm 250 smoking


Probably due to a bad crank seal on the clutch side. The extra smoke is from the trans fluid burning through the cylinder.
