I have put about 3 miles on my go cart 429. I noticed my left front wheel was loose. I have Trigo wheels with knockoffs. The round nuts/pins that hold the adapters came loose. I tried to tighen them by torquing them to 80 pounds. Two of them split in 2 or 3 places. How tight should I make them? My left rear also came loose. It took me about 3 hours to get my wheels back on the car. Major pain in the you know what. It seems that these nut/pins are junk. I think that they mushroom out from tightening them. I got them from Trigo. The wheels are great. Anyone having the same problems??? I had to grind the nuts/pins to a taper to even get my wheels back on my car.
