Is it normal after riding for the final drive to be too hot to the touch? Just got doing 100 miles, and was surprised how hot it was. Thanks!

Did you check (re-check) to see if the drive is full? Just askin'.Karson said:That's why I asked...just did my first service with 75w-90 mobil 1, and it was super hot. That was pushing it at 85 on the interstate for 30 miles, though

I will triple check tomorrow, but my fluid level was barely leaking out of the fill plug before I sealed it up. If it's good, then it is what it is I guess...stevepsd said:When I was doing my brake rotor temp checks last weekend for another forum member I shot my final drive temps as well. Ended up doing over 50 miles @ 65-70mph in different stretches.
The final drive stayed a pretty constant 155F throughout. The ambient temps in the upper 70's. I am running Mobil 1 75W-90 Synthetic in there.
Pretty normal temps.
yes, this bike is very sexyKarson said:surprised how hot it was.
I opened up the filler bolt on it and just a bit of fluid trickled out, on the center stand of course. So my level was fine. After thinking about it...155F is pretty damn hot to the touch, so all that heat radiating from the cooling fins and metal housing isn't going to feel just warm like a standard cager differential would.EricV said:It's normally cooler with the synthetic gear oil. I usually spin the wheel a bit to get a tad more oil in when doing the changes.
Your findings are pretty common on here.Karson said:I opened up the filler bolt on it and just a bit of fluid trickled out, on the center stand of course. So my level was fine.

At 600 miles, mine appeared low on oil and ran very warm (too hot to keep your hand on there). I've since changed the diff oil twice and can report it runs much cooler now.... probably because it has broken in and the oil level is full.
I'm with you. I plan to buy a quart of Mobil 1 or Valvoline Synthetic and just flush it with each oil change (4k miles) until I stop seeing metal. Then I will switch to the factory interval. Since the drive only holds .2 qt I figure I can get a solid 4 changes from one qt. That will bring me to the first factory interval for ~$20 in fluid.~TABASCO~ said:X2... changed mine a few times to 'wash' out all the crap in there. Use the Mobil - 1 and now runs quite a bit cooler. Although over kill, I just change it with the oil every 5-6K or so, running full synthetic.
