Any one know what my jetting would be around on a raptor 660R with: Exhaust Baffle Completely Removed, Snorkel Cut off and 4 1 1/2" Holes cut in the airbox. My elevation is roughly 200Ft above sea level, and the tempature is around 30 Degrees. thanks!

 

idk what the stock setting is but you wont have to go too far on the main

Do a little searching on raptor jetting, its probably in the top 10 thread topics of all time.

 

do a plug check, ull find out exactly if ur too lean. if the plug is a lil white then richen ur main jets. u should know that from ur 250r [img]i/expressions/face-icon-small-wink.gif[/img]
