Hi guys, I am still having top speed problems with my Artic Cat. I only can go about 27 mph on my machine. I added seafoam to gas, checked air filter, and was about to change the oil but realized I didnt have a socket that big. BTW, what size socket will fir the oil drain plug? I don't know what else to do. It is in hi gear and it runs fine just slow as hell. Any suggestions?
