Just purchased a 2011 Grizzly 450 with 560mi. Installed a Warn winch. Looking at placing a Uni filter on it and if so, do I need to adjust the jets? Want to make sure I don’t go too lean? I am at 1k feet above sea level and want make sure its jetted well. The next item is shim/spring. Live in KY so we have Hills etc. Will keep the factory tires for awhile. If I get another set in the future, will not go extreme. What shim/spring combo should I go with. Seems like the stock setup keeps the rpms a bit high. Looking at fabricating a rear rack seat cover to hall a few people as needed. Any other suggested mild mods/accessories?
