Need a good starting point

[burhead]

I have a basket case 95 banshee that I just got done rebuilding. It has fmf fatty pipes, a foam airfilter in the stock box, boost bottle, delta reeds and a shaved stock head. I was looking at a good starting point. The guy that did my machine work is a polaris 2 stroke guru but does banshees and 250rs aswell. He recommended going rich on the break in (as I have done on all my polaris motors) and recommended somewhere around a 290- 300 main. I put the 300 main in and left the pilot alone. I still have to get the motor back in the frame but I was wondering what others were running.

Since nobody answered your thread (or mine)-ill help you out.i would run a 300,(you'll prob end up around a 280 in the end) like you are.you can always go leaner.break it in properly and check a plug.dont check the plugs for at least your break in period and a good ride.its going to be wet looking/rich because your rings need to seat first to give an acurate reading.blow by from rings not being seated yet wont give you proper readings.i would ditch the lid and install a k&n after break in..check plugs after break in first though-if your rich-just ditch the lid to lean you out and start there.
