I'm running Redline Shock heavy in the tranny and Redline Hi Temp ATF in the primary..... still undecided on the donk so have standard HD 20/50

everything I've read/heard about Redline has been good.. including a reduction in wear on tranny

Penrite do HD oil which is a 50-70 weight. That works good in hot running early Harleys.
It's a little easier to get.
Penrite Enduro from Auto One is 25w 70; it about $29 per 4Litres.

For V8, V12 cars & large displacement m.bikes I'd go Penrite SIN 25.

I wouldn't mind if someone could start a thread about oils and what all the terminoligy is about ie 20w 50 and how they all differ as I am a mechanical numnut.

iam with u stix .good combo ...

has anybody used redline oil a  in primary of a 006 sporty,im told the oil is of high quality and as the bike has to last this old man for some time would appreciate advice on it or any other that has given someone good results,many thanks
