Jetting a 09 Grizz 450

[Colorado Kid]

I have a bone stock 09 Griz 450. I would assume the carb is jetted for sea level. I live at 5500ft and do most of my riding from 8000-10,000ft. had it as high as 14,000. Pulled the spark plug and you can tell its running rich. But seems to run good at high elevations. Are there carb jet kits available for the grizzly? Dyno-jet is one that comes to mind. Has anyone else had to rejet for higher elevations? Thanks.

Dealer rejeted my 450 befor I ever took it home and has always ran great. I say if you have a good Dealer they would have rejeted when you bought the quad. but I know some will some wont.

Mine was used with 40 miles and 10 hours on it when I got it from the dealership. The previous owner purchased it from the same dealership. I will call them today and see if they have records of a rejet. I doubt they did it.

My brother in-law bought one at a differnt dealer he asked them about rejeting and they said they had never heard of such a thing. I would never buy a quad there.

Post up a pic of your plug. Most likely it's spot on as they are jetted very lean from the factory. I went up over 10 points on my main jet with just a uni filter and modded stock exhaust on my 06 kodiak and was still a little lean.
