93 banshee

[ksf3377]

just picked up another shee. its a 93 with t5's, noss head 20cc domes, v-force reeds, k&n filters.... when i ride it, its like it is dripping gear oil from the exhaust clamps and little bit... does this mean the rings are toast? it runs mint though so i figured if the rings were that bad it would run terrible. also could it be sucking the oil in through the reeds? im still a bit of a newb so some help from the hq pro's would be greatly appreciated!!

Not really...a little unburnt fuel and oil get pushed out the exhaust, it could just mean the seal on the header pipe/stinger tube is bad. It happens.

You can get high temp reinforced hose to seal that for pretty cheap, usually 20 bucks or so.

 

I would start with a compression test to see the health of the motor. Use a good compression tester.

While nothing can substitute pulling the top end off and actually measuring everything to check actual wear, I have a hard time telling someone to pull apart a top end when the bike is running good....

 

If you're at or near sea level...a noss head with 20cc domes on a stocker motor will put you roughly in the 150 to 160 PSI range. If you're in that ball park, I say run it. Get new seals for the pipe joints.

 

Here's examples

 

for a 1.0 diameter stinger:

thanks for the links. im sure that it is not unburnt fuel though. It is picking up gear oil from somewhere. if the crank seal was shot would it still run good?

If the crank seal is bad on the right side (clutch/PTO side) it would normally foul that spark plug...and the smell of burnt tranny fluid can never be confused with burnt two stroke oil...lol.

 

Normally, a bad PTO crank seal won't leak enough to show a real noticeable loss of fluid, but it will foul the plug quicker and tranny fluid usually doesn't burn quite like two stroke oil...so it won't run great.

 

It's very, very hard to tell if the rings are worn or are still good...especially since you just got this bike and don't know how it ran when it was "fresh".

it has been sitting for a couple years. Im going to go through it tonight a bit and do a compression test when i get out of work and see where i am at like you said. If all is good then i am going to run it as is. thanks for your help it is appreciated.

My pleasure...

I would do a search here for leak down tester. You can buy one cheap, or make your own and it could save you some grief and money....IF it is a crank seal and should it happen to get worse...

 

Good luck...
