Im new to brutes but i bought a quad with 500 miles on it, it hadnt been ridin for a few months when i test rode it the thing ran fine when i went out all day it started to spit and sputter. I think some junk got stirred up and got into my pilot. I had to ride with the choke on. Any advice on jetting would be great i know they have issues being lean. And we ride in the winter here in mn so its probably really lean. Any help would be great i had a 650v2 cat so i know how to take carbs off etc. Thanks.
