Good starting point?

[bryan b]

Hey guys, working on a buddys banshee. New motor and trying to see what a good start point would be for jetting.  

 

Elevation 803 above

 

66mm bore, 4mil stroker, head milled 20 thousands, fmf sst pipes, +6 timing plate. Running belray h1r syn oil, pod style air filters, stock carbs, Stock porting.

 

just looking for what ya all think will be a good start. 

 

also, we are going to Waynoka this weekend. The elevation change is from 803 to 1500 ish. If we are good at 803 is the increase to 1500 enough to have to rejet? 

 

Thanks in advance.
