siezed-up Posted July 2, 2008 Report Posted July 2, 2008 Hi, I guess I'm new to a stock Banshee. I've built a couple with close to 200 psi compression, but I can't find what the minimum compression values should be for a stock shee. I did a search here but I got into way more stuff than expected. I'm running about 120psi on each cyl. If elevation is an issue I'm about 2000ft above sea lev. Quote
black sunshine Posted July 2, 2008 Report Posted July 2, 2008 Sounds high, may be your guage. Stock is around 125psI@sea level Quote
mopar1rules Posted July 3, 2008 Report Posted July 3, 2008 (edited) no that doesn't sound high. sounds just about right. actually, sounds perfect. Edited July 3, 2008 by mopar1rules Quote

ClimbAnyHill Posted July 4, 2008 Report Posted July 4, 2008 120 sounds right for your elevation! it prob be perfect at sea level. I would get that stock head milled and bump up the compression! Quote
mopar1rules Posted July 5, 2008 Report Posted July 5, 2008 I would get that stock head milled and bump up the compression! i agree. shave it .020" to .030" and call it a day. Quote
