So I messed up!

[Screaming Yellow Zonker]

I had the engine out of my Banshee because the case was broken. I got the case welded so thats all taken care of. While the case was spit I installed a 4mm stroker crank and also added a Trinity Stage IV head. So I got the engine back together today and installed and decided to take it for a ride. I go around the block and pull back into my driveway and notice a nice trail of smoke behind me. So now I have to determine if the case didn't seal or if I blew the crank seal out. This sucks!!!

ummm, two strokes tend to smoke, especiallly when cold and/or running rich. And if you put in extra premix for break-in that could be why. Do a leak down test, that'll tell you whether or not you have a problem.

[Screaming Yellow Zonker]

the left side is barely smoking and the right side is puffing bad. I am going to test all of it tomorrow.

[badassbanshee479]

sounds like a bad cranks seal on the clutch side.

first place I would look.

Also you should always leak test the engine before ya put it in the frame, that way ya know it is sealed!

the left side if your looking at the back of your shee?

 

is your choke on?

[Screaming Yellow Zonker]

Excitement got the best of me so no preliminary checks. I am hoping it is just the seal (even though it is brand new). It would suck to have to crack the case again just to reseal it.

 

I always refer sides as I sit on the bike (something I picked up from working on cars) clutch side is right side and stator side is left side.

 

I'll take a pic of the smoke in a little bit.

[Screaming Yellow Zonker]

Oh the clip that holds the choke out (detent clip) broke on me so I have to hold the choke to get it to work. Oops :biggrin:

[letsgetthisdone]

Sorry to tell ya, but you have to split the cases to change that seal.

[Screaming Yellow Zonker]

Yah I know all about that. I am going to see if I can cheat. I don't really want to split the case again.

I really dont think you can get that seal in without splitting them. That would be cool as heck if you could though, let us know how it goes.

[Screaming Yellow Zonker]

Thanks. I am going to tear into it monday.

 

here are 2 pics of what it's doing.

hmmm, you could've broken a reed petal. Just somethin easy to check before you tear it all the way down.

[Screaming Yellow Zonker]

The reeds are a few months old so I never thought about that. It is white smoke but the plug shows no sign of coolant. and it is only the right side so that led me to believe that it might be a crank seal. I will rip the reeds out tomorrow and check them out.

 

Thanks.

did you resnyc the carbs?

[Screaming Yellow Zonker]

did you resnyc the carbs?

 

Yep I double checked them before I put the pods back on. I am thinking I should pull the head and check the O-rings. It doesnt smell like oil or coolant that is the weird part.
