Definitely can't afford a new cylinder. .. and since it's a big bore I'll have to have the same 392 bog bore or new pistons and rings... fml

Na the cylinder is cracked around 1 of the bolt holes..

Well it turns out I bought a banshee with a "new" big bore kit that aactually has a cracked cylinder. .. so I got fu**ed as usual.

Ok guys well you know what i need. Who's got it?

Oh haha. I'm not opposing any of you guys but why can you buy any of them individually new?

Ok so i guess i need a matching upper and lower case or a complete bottom end.

What other thread??

Saying***

Are you sing i can't replace just the bottom of the case?

Dang that's what the company I ordered the Jets recommended and sent. 280 290 300 and 320. I hope the new cylinders aren't warped..

Yes but won't the air leak cause a super lean condition?

Well I really only need the bottom of the case because part of the slot where my kickstart goes is broken but that means I'll have to tear the entire engine down. .. which I've never done on a banshee. But if I can find a complete one for a good deal then I'll go that route

Looking for bottom end. Can't break the bank. Thanks

Oh and no air box and dual k&n clamp ons. Elevation is 425ft asl.

No it don't rev past 1/4 at all. Anything past 1/4 is bog. It's a 392 cc big bore. Fmf gnarlys and power core 2s. Fiber reeds. Boost bottle. Cool head not sure what cc domes. I have 30 pilots and have tried 300 and 320 mains.

Perfect. I bet a new gasket will fix 95% of my problems. Thank you!

No i had issues i couldn't figure out the cause of so i did a leak down test yesterday. The soapy water was bubbling around the base gasket at front of engine. I bought it from a guy who just put a big bore on it and never even rode it because it wouldn't rev past 1/4 throttle. So i got it extremely cheap. He thought it was jets. Which the Jets were 260 which was way to small but i replaced those and it still isn't right. So my question is could that gasket cause the severe bog and could it cause it to be hard as hell to start??

It was running bad and wouldn't rev past 1/4 throttle

Lol well its not blown up so what else?

So I have been ha ing alot of problems with my new shee. .. after alot of tests I found I have a blown cylinder based gasket or some sort of air leak in that area. What problems or symptoms could this create?

Well I found I have a blown base gasket with a leak down. Will this cause my problems?

Any help guys?

So my coil is supposed to read .28- .38 on the primary. It reads .6. What do u think?
