Ok. Well mine did have liquid in the case and your sons did too. So maybe that’s why it won’t run. No I didn’t do a leak down test yet. I pulled the cylinder off because I thought maybe the piston had a hole by the exhaust port. I will put it back together tonight and see where it’s leaking from. I appreciate your input

and it was a bad crank seal that was causing it?

There’s definitely fuel but I’m thinking it’s transmission oil. I’m going to do some testing later tonight and get that crap out and see if it runs. A little trial and error. I’m confident it’s the crank seal

It’s in the case, by where the crank skits. I was riding it when it started to run bad. I have the right cylinder off.

Since it ran well last, nothing changed in terms of swapping parts. After further inspection, there is oil where the crank sits, indicating a bad crank seal. So yang would explain the smoke but no exhaust pressure

And why is that? I have spark? The carbs are good and so are the reeds. Jetting is the same as it was when it ran good

The head gasket only has about 10 hours on it, and it looks fine. I didn’t get any scent of coolant, mainly oil and gas. I’m just not understanding why I don’t feel much exhaust pressure out of that pipe. Where does the air that’s being compressed go? And smoke is still coming out

Hey guys. So my banshee is having some issues right now. The left cylinder fires fine, but the right cylinder has smoke coming out, but there isn’t much exhaust pressure coming out. Raw fuel and oil is spitting out. Spark plugs are fine, and so are the coil wires. Thought it was a carb issue, but switched carbs and nothing changed. Also switched reeds, nothing changed. Inspected the right crank seal, and it appears to be ok. Also, the compression is good, reading about 95 psi on both cylinders. The right piston is intact, no holes in it or cracks. Main jets are a 220, and air screw is about 1.5 turns out. I live in Loveland Colorado, relatively high elevation. Don’t know what the problem is and I’m getting frustrated. Any input would be greatly appreciated
