Transmission (Gear) Oil
I've got a 2002 Fat Boy that I'm getting ready to change the tranny fluid on. After much research on the topic I've purchased some Mobil 1 synthic 75W90 gear oil, but now I'm begining to wonder if I should have gotten one of the 75W140 gear oils. I was a bit concerned about the 140 weight and that's why I opted for the 75W90. What are you using and what would you recommend.

I was running red line shockproof heavy, but now the local HD stopped carrying it so I went to pick up some Lucas 85/140, but all the auto stores were out so I went with Royal Purple 75/140
