if you cant plugchop...

If everthing else is correct, float level, air tight, idle set correctly, stock needle on middle clip.

Slap in a #300, if it babbles its brains out, come back in sizes until it gets onto the powerband and pulls hard, otherwise leave it alone.

A #300 is not going to kill it.

Take a handfull of jets and plugs to where you can find a long enough place to get the WOT and do aproper plug chop.

i was at a 300 and the plug fowled constantly, im at 290 now and its not fowling.
 
Is it getting well on to the powerband, if it is go with a #290 and plug chop as soon as you can.

All care , no responsibility taken.
 
With a forged wiseco 66.50,fmf sst full kit,vforce3's,k&n,+4 timing i was at 280 and still a little rich but i prefer it to be slightly rich.This was with a stock needle middle clip,and stock 32.5 pilot.

Id say you could go to 270-280 easily and it would crisp up your throttle response and powerband.Or leave it as is if youre happy with it.

My banshee has 2 size larger mains in it for a safety net.
