Jetting stock '09 800R

[Ridin High]

Hey, are there some people that are changing their jetting on their 09 summits, by putting in lower main jets. Anyone there to say they have and what jet size they are now running? thanks.

FYI,,,Put a Racepac on my 09 800XP just to see what exhaust temp were at . Sled is totally stock and temps were as high as 1250 mainly in the midrange, drop to 1150 at WOT. Temperature that day was 14 C.
