R100GS Fork oil

I believe that those in the know on this forum recommend using a 7.5wt fork oil for the airhead. What opinions do the collective have on using ATF. I'm about to change my fork oil and have found a container of several litres of Morris liquematic DII ATF stashed in my garage. I have read somewhere that ATF can be used in forks, but I'm unsure about airhead forks.

7.5wt is for the earlier bikes. If you put that weigh in a para front end you'll be all over the place. The recommended fork oil in warmer weather is 15w for the para. If you want to sort your front end out then fit the spacer tube from a pd in. It'll transform your front end.

one of the guys came up with a mixed fork oil combination for paras. It's called the millichamp cocktail if you fancy searching for it.

The Howard Millichamp Formula

The Howard Millichamp Fork Oil formula is:

Left : 75% 15wt, 25% 20wt

Right : 100% 15wt

I've got it in my GSPD and it's a big improvement!
