If your problem started here, I'd suggest draining the Mobil 1 and while there, do the adjustment procedure. Refill with a different lube. Since the HD Formula + is easy enough to get and known to work, try that and see if the slippage disappears or continues.Thanks for replying. Guess I need to give details about situation.
The bike has been serviced every 5000 miles just like required. The bike has 47,000 miles on it.
I have taken it to the dealer right on schedule this entire time. I am riding out west for a big trip so I decided I would change the fluids myself for the first time. I researched it and read up on it. It appeared to me it would be OK to use Mobil 1 20/50 oil. After doing that is when the slipping started.
