I don't know how y'all take the two halves of your primary apart but I had to use a press and put about 2300 lbs on two wedges to get it apart. (XP 800) Then when I put it back together I couldn't get the two Pieces to stick back together like they were when I took it off the output shaft. I tried to pres it back together and put 16,000lbs on it and it still just came back apart. Is it suposed to stick back together? I just put it back on and torqued the bolt down. I took it for a few spins around the yard and seems to be fine. I didn't have any weights in my pins by the way. I put made it so there were 16 grams and am going to go ride tomorrow. Hope that helps with my belt burning and clutch heat, and shifting problems.
