need jetting help

[killer454]

I have a 1999 with the following parts need a good place to start the jetting for spring im just buying the jets right now will have to jet it later when spring gets here.

 

mods

pro-circuit platinum headers with 304 silencers

coolhead with 22cc domes

boyseon rad valve reeds and cages

66mm bore

stock ports

k and n filter with outer wears no box

 

the bike has 300 mains and 30 pilots right now

 

what should I order from rocky mountain as far as jets I have to place a order for parts on another atv just figured I would go ahead and get my jets now.

 

I live in mid-Missouri so should be around 800 ft above sea level I think

 

thanks for the help

25 pilot and that 300 sounds like a good start on the main

maybe order some 280's-310's

330/280/290/320/310
