banshee199

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.

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 have a 420 big bore banshee I need size 71,s for domes for my new noss head, I was told by patriot racing that the dome size was so big the head would probably leak. Does anybody have any experience in this big of a size domes? Thanks!
