no one can tell you exactly, you would have tostart big and work down doing plug chops to find out. Are you running the stock 26 mm Mikuni? Whats your elevation? Prob safest bet is to start with a 330 and adjust from there
If you have the stock header then you need not go too big.
If you have a FMF header it would call for a #260 alone.
With only the FMF Powercore silencer, no jet change is required, same for the V Force reeds.
The BBK could call for +2 sizes, and the open air box another +2.
#270 - #280 and plug chop to confirm.
FMF = #260 main jet.
Aftermarket air cleaner + 1 or 2 size larger.
Air box lid off +2
32:1 pre mix +1
Needle in the middle slot.
32.5 pilot jet
Plug chop to confirm, as temperature, elevation and humidity come into the equasion
