Hello! I recently bought a 07 Sportsman 450 and am in the process of a complete recondition and maintenance. Of course once oil and filter is changed I head for the grease gun and find that my normal gun will not work. Looks like the Sportsman zerks are smaller than normal automotive so will not take grease. Am I nuts and if not what size zerk tip do I need for my grease gun for my Sportsman? Thank you for the info, this forum has been a big help in this project.
