Diff oil

[ErgoMot]

New to the Lehman trike, I was wondering what oil to use for the diff.

Do I use the 80W90 that would normally go in to my GL1800, or an other spec oil?

I used 80w90 Synthetic, it's just a 6.75" integral type Ford Pinto rear. Don't overfill it.

I usually use Valvoline regular non synthetic 80w90.Lehman originally recommended regular diff oil and for me it seems to work just fine. When you fill it, fill it so you stick your pinky in the hole and the tip of your finger should just be touching the oil.
