I bought Mobil 1 for my 1200R because I've used them for years in my WRX, but I've used Amsoil in my 800 ZR snowmobile, so I guess I could try that too. Thing is, Advance was having a sale for $42 you got 4 qts of Mobil Syn V-twin and a fram chrome filter. Amsoil doesn't have a retailer up here that stocks the 20w50 right now - but maybe next time I'll order it in if the price is fair.
Has anyone tried the new Mobile syn in their sporty?

My iron has 7000 on it. I have a service plan at the dealership and they have been using amsoil 20w50 top and bottom on my bike. Is the 20w50 gonna hurt my bike if i switch to the amsoil gear lube after my service plan runs out? I dont thnk they have the gear lube. I guess i could buy a quart since its just one quart capacity.

Personally, I'm using the Formula+ in the Primary and Amsoil 20W50 in the engine. Only because my bike shifts so smooth with it, I don't want to mess with it. I'm sure the Amsoil would be just as good.

Since the 5,000 mile mark I've run RevTech 25w60 in the engine and Harley Formula+ in the tranny and the cHarley recommended 63813-90T oil filter. To my ears the tranny shifts much quieter using the Formula+

Yes,it's OK to use it, but if you're using Amsoil, they make a 75-90 Gear Oil that's better suited for the primary/tranny.
All motor oils contain an additive package that's designed to deal with the nasty combustion by-products in the motor. This additive package is useless in a gearbox. Gear oil contains an additive package which is designed to deal with "molecular shearing" which occurs in gearboxes.

This is from Amsoil: AMSOIL 20W-50 Synthetic V-Twin Motorcycle Oil contains no friction modifiers and promotes smooth shifting and positive clutch engagement.
How does this square or not square with what you wrote concerning "additive packages"
