Fork tubes are turning while riding...?

I know someone whose pinch bolt broke and the front end collapsed when he was riding... (he didn't realize the bolt was broken). If I'm not mistaken, those bolts are NOT grade 8 bolts so you might want to replace them if you are going to tighten them beyond spec.

Well, the lower triple clamp is the important one...and the pinch bolts are what holds your front end in proper placement. The top ones are only there to locate everything and should NOT be bearing the weight of the bike. If you have been riding this way for a while, I would take a very careful look at all the parts before just tightening and riding away. The top tree may be cracked, the neck bearings may be toast...etc etc. Check everything well. If you lucked out this time...torque that lower pinch bolt (triple clamp, not axle), and check the alignment of your front wheel, axle, neck, and bars. They could easily be tweaked now.

Shhhh. Some people refer differently to parts of the bike, hence why I asked.
Everything seemed fine. Ill recheck though.
Good idea, since I didnt use a torque wrench.
I had the bearings checked by HD last year and they were good. I thought they were seated incorrectly because it looked off after I had the trees powdered. They did the fall away test and it was good.
I think shes going to go in for a total check this winter.
Yep, pinch bolt is on the bottom triple tree right where the fork passes through it. Sounds like it needs to be tightened. First though, I'd remove it to be sure it isn't broken before you tighten it down. They do have a history of snapping off inside. I've seen it a few times and read about it on here as well.

Well when you posted "Its fact that the tubes are moving not the blinker.
Pinch bolts are on the bottom arent they, below the axle?", I thought it would be better for someone that knows the parts of a bike a little better to fix it. Having the tube rotate & thinking the pinch bolts were below the axle is a little scary. I assume the bolts you were referring to were the axle clamp nuts on the bottom of the right fork tube. Since they are only on one side it's a give away they don't hold both forks in, just the axle. I wasn't trying to be a wise guy but sometimes it is better to step back and have someone that knows assist you.

I've had the left side pinch bolt break on my bike twice now. I won't use a Grade 8 for this, since if it breaks again, good luck getting an EZ-out into a Grade 8 bolt.
I use Grade 5 bolts, but I replace them every two years as part of my routine maintenance. In fact, they're due now, come to think of it.
35 foot-lbs is the correct torque, IIRC. I never use a torque wrench on my pinch bolts because it won't fit under the fork tins on a Heritage. I use the longest box wrench I can get and as much force as a 62 year old man can muster.
