WTF!

My Banshee has recently turned into a B*TCH!! Heres the deal. It ran fine last week... i get on it today and its runnin horrible... the plugs are black and its blowin' hella oil out the left silencer. The oil comin out is real runny almost transparent. It seems to rev on the the low end but not go anywhere. I dont think its the clutch cuz i put one in it just a little while ago, top end is sluggish. I figure i have cracked a ring or something... Any ideas??? Thanks,

Check the compression

Your air cleaner clean? (sounds stupid but I did it the other day)

Check your crankcase seal.

Would a bad crankcase seal make it leak oil out of one of the cylinders?? My air filter is clean. Could it be that i need new rings?? I've nver had to rebuild it and its been a year since i got it. Thanks.

Sounds to me like a bad head gasket leak. Usually when you have a right side crank seal leak it will spew oil out the right pipe, It will not be describable as almost transparent, it will be dark. If you have a crank seal leak on the left side, it will such air and lean out. That plug would look ashy, possibly have metal specs all over it depending on how bad the air leak is and how long you ran it that way. I would also, as mentioned above, do a compression test. It may show an obvious problem in which case you will have to tear it down anyway. If your compression test looks good, I would tear the head off and take a look at the gasket. You will need to replace it, so have a spare(unless you run a cool head or O-ringd stock head). If you have the means, a leakdown test would also be a good idea, and would indicate if you have a bum seal or air leak of any sort.

Compression AND a leak down test. Compression test alone will not check for leaks in the crankcase or crank seals.

 

Go from there...
