Maxima 50w 60w 70w

[tresi]

Pro mod., big inch motor, funny cars,

Yeah i think i read top fuel runs 70w

We didn't their oil but yes 70wt in nitro motors

So I guess no one thinks it is because the earlier Harley's ran large roller bearing cranks and have almost zip for oil pressure without heavy oil?

Nope. There is more to life than a Harley.

Thats a polite way to put it...

Well then you might wish to go to the Maxima website and read what they say it is for. Here is a hint..."Early Harley Davidson"

Back when I was still a Harley rider (40+ yrs ago), I ran 50wt in my XLCH and 70wt in my FLH. This stuff is not made for Nitro, other 70wts maybe, but not this stuff and the question was about Maxima 50 through 70 wt oils.

Im sure your right i just love to hate puttley gayvidsons

I prefer to hone my skills while riding moto, enduro, supermoto, dh mtb, and bmx, even unis, vs sitting on something thats like a hybrid between a lawn mower, couch, and unbalanced washing machine, and all the weight of my bridgeport, with a usually pretentious rider and an ungodly low hp per cube.

LOL

The Harleys I owned used roller brg big ends & mains, reqd SAE 50 oil & ran quite low oil pressure, 30 psi IIRC. That is because roller/ball brgs do not need a lot of oil for lubrication, but enough to carry heat away.
