Hot banshee!

[banshee199]

I have a 99 banshee that I just rebuilt the top end again, like before one of my pipes is getting really hot while the other one is cool and it is jumping when I give it gas. It is a 420 big bore on its last bore with trinity stage four head with 21cc domes and fmf fatty pipes 280 jets. I thought it could be electrical so I swaped spark plug wires over and it did not change maybe I did not put rings in right I noticed they are not marked any input!!@!@

I don't know that I'm getting what you are saying. Is the "cold" pipe actually cold like it's not running? Or are you saying the other cylinder is running too hot? why did you need a new top end "again"? Is the one side running way hot, melting rings while the other is normal (look for air leak). Need more info. Also, what is you elevation, and are you ported?

The cold side is running and firing and yes it is ported trinity stage 2 supposidly and the elevation is like under 500 above sea level. Thanks for reply!!! The last time I ran it right after rebuild I thought I just did not break it in and the top of the piston broke off right at the top ring trinity did the measurments after I sent the cylinders to them, but I did replace all parts.
