my banshee has 0 compression in both cylinders

[sToCk7miLL]

just spend the cash to get a bore job and new pistons......

ur better off that way.... as far as the "metal gasket" get a new one.... after you torque it the gaskets no good...... MAKE SURE the raised part of the gasket is facing upp. i use threebond to seal it up...WORKS WONDERS .. compression checks are to be done when its warm... i would focus on the reeds make sure they arent stuck or show daylight... get a bore job and new pistions seal it up and go from there

i'm thinking you guys are right, just get it bored and new pistons/rings. first i need to fix that frame damage though. thank you for all the comments.

This doesn't make any sense. Even if your rings were finished, it would register some compression. It is damn near impossible to register 0. Even with no rings installed it would probably still register compression. I've seen pistons with holes burned in the center of them still register like 40 psi. If the reeds were stuck closed (which I have never seen), it would still have compression. There is still air on top of the piston that gets compressed when the ports are closed. So, unless your pistons aren't moving, you are going to have some compression.

 

Does it feel like there is any compression when you kick it? Get a new gauge.

exactly what i was thinkin theres got to be some compression, try a new gauge for sure. Manufactures of those gages do make mistakes and maybe you got a bad one!

reassembled and cleaned the carb....took a lot of kicking but i finally got it to fire up, open header...holy crap!

[Valin]

Well, there's certainly compression there if it runs. Mind you, I'm surprised it would even run with no exhaust on it.

I think he means it had a head pipe but no silencer. I did it with my CPI's for a sec it was VERY loud.

[Rodneya]

It will start with no exhaust. Not easily though, and wont rev.

And it is stupid loud.

[AKheathen]

actually, it fires up pretty easy, damn near 1/2 kick with no exhaust, and if you are already running alot of fuel, it will rev. after all, the modern exhaust is relatively new to 2 stroke engines. what i was getting at was that a stuck ring can act like no ring, and i can see some gapping in the cylinder......enough to warrant new pistons/bore, which would require some dynamic kicking to turn much compressoin at all, ringless.

i mean't no exhaust...at all. i actually bruised the bridge of my foot and have been limping for days from kicking that stupid thing over, i swear i must have kicked it over 500-700 times (and i wouldn't consider that an overestimation)...i don't give up easily! but yes, it needs a bore/piston set. might just say screw it and sell it.
