Final Drive Assembly Replaced Running too hot?

No, it doesn't sound right for me. :?

Mine doesn't run hot like this so it might be a problem.

I went on a 100 mile run today with a Yamaha shaft drive (700 lb bike) We stopped after 50 miles. I check, buy hand, the surface temp of his rear end and drive shaft assembly. It was warm and did not feel uncomfortable to the touch. I felt mine and was unable to keep my hand on it for more than a few seconds before it became too uncomfortable. Same for the drive shaft housing.

Can someone else please see if you can keep your hand on the rear end assembly? Can someone else measure the temp? I'm running at 144F today. I measured the case and the oil temps.

Ride it like you stole it.

If it can't take that, get the faulty part replaced, pronto...

My only worry is that it may seize. Once I get concurrences on the operating temp from a few guys, I'll probably feel better.
 
If my bike was running, I'd try it to compare for you but from your temperature readings it doesn't sound too hot. Your ambient temperature will also affect how hot she gets. Are you running on pretty hot days?

If your oil level is ok then another thing that could be amiss is that there isn't enough grease on the bevel drive interface with the rim. You'd have to take off the rear wheel to check that though. Be unusual if they didn't grease the bevel drive but I've heard worse things forgotten at shops before.
 

I'll try doing the rear wheel check. I did it initally while troubleshooting the original grinding problem...but haven't done it again since final drive was replaced.
