[banshee7]

hey guys i just bought a set of fmf sst's off ebay with powercore 2 silencers.

 

i need to know what jet sizes i should use. the shee is all stock.

[2strokesmoke]

depends on elevation but i would start at about 310 ish maybe up 1 on pilot(27.5) hope this helps

stock airbox main 260, if you open it up and add a k&n go up to 280, 27.5 piilot fmf likes a fat pilot circuit, run the needle clips down one, you should be good to go

is that 27.5 pilot for the k and n filter? or just stock airbox. because my shee is bone stock motor wise.

260 mains for stock air filter and lid on. I'd start with the stock pilots

and adjust your air screws. May need to go up to 27.5's.

I would strongly reccomend a pro flow air fliter kit with K&N filter.

That stock air fliter assembly will fail you eventually.

And with the pro flow kit, you can pull the lid off.

 

Im at sea level and I had 340 mains, 27.5 pilots, air screws out 1.5 turns and needles in

stock position with no air box lid with fmf fattys and it hit pretty hard.

if you have the lid on, do yourself a favor and pull it and the snorkel on the front. then throw in a 300 main and see what you got. the pilots, 27.5 would be a good choice.
