Thanks!!!
Yes, I'm running with the aluminum diff and it's 4 gears, they are brand new, but I'll check to see if they are loose or something. If they were loose, what can I do?
Another thing is the middle belt. Using the 23T on the front works fine, when I was going to try the 22T, the belt felt too loose, so I went ahead and replaced the belt with a new one, but it still felt too loose, what can I do?
