Man, I gotta say, After installing RP 20w-50 full syn in the crankcase(and ATP in the primary) the scoot really seems to glide along more easily. And I don't hear the clattering of the lifters and valves quite as much. It's kinda pricey, but so far, I think it was a good decision.

I've seen where many guys love RP. I've never used it as it's not readily available around here.

Replaced my tranny gear oil with RP from Mobile 1. Shifts better and is quieter. Also finds Neutral much easier now. I'm happy.

I have an 07 road king with 4400 miles on it. I am considering RP max cycle for my 5000 mile service. Any more input on this would be helpful in making my decision. Also can I use it in the engine, primary and trans??

I have checked RP web site and I am still not sure what to about the trans and primary oil. Hopeing someone here can help with that. I used RP in a Road Star and had great results with it.
