Rear axle bolt 'rattle' on potholes
Hey guys. Been searching around on the internet and this forum for an answer and can't seem to find anyone with the same issue.
I just finished putting on new tires, sprockets, chain, and shimmed the cush drive. I put the wheel back on the axle (with the spacers correctly oriented), got the alignment straight, proper chain slack (it's at the tighter end of the specs), torqued the axle nut to 110Nm and installed a new hitch pin, and torqued the torque link nuts to 32Nm. Everything seems super solid on the swing arm.
The problem is that now whenever I go over a large pothole or sudden drop in the road, it sounds like the rear axle bolt is rattling around or there is something loose on the rear axle. I'm not sure if this is exactly what is happening but that's what it sounds like is happening. It's really weird because whenever the bike is on its center stand, everything feels really solid. I had a I first noticed it going about 5mph over a decent size pothole kinda bump in the road. The bike seems to run great just cruising on a smooth road.
I had one of my friends ride it and he said he didn't notice anything wrong with it. Any ideas on what this problem could be?
