fastbanshee8 Posted May 16, 2010 Report Share Posted May 16, 2010 this isnt my banshee its my friends, hes also like 265lbs. he runs a open air box and he says plugs are white, maybe too lean? If the plugs are white, it's lean as hell. Do not run it, until it's rejetted richer. Start with a 350, and see how it works. Quote Link to comment Share on other sites More sharing options...
Snopczynski Posted May 16, 2010 Report Share Posted May 16, 2010 I would pull the needles and nozzles out, and run at least a 370 main jet in it to start. You need to make sure it has the right components in it first. Quote Link to comment Share on other sites More sharing options...
