I found the Minton Mods in 650Central. http://www.650central.com/I have searched "Minton Mods" in this forum and get only references to the article. Can we assume that the 6" measurement for oil fill is with the fork tubes vertical? Further, I did read the "Minton Mods" article (which I cannot find) and remember he reccommending a 36mm fork seal. Does that still apply?
i put hydraulic oil in my xs2 forks . 230mil . or 230cc in each sideOne of us lazy b-stards should compare that to a spring in place level. Cuz, well who wants to take the springs out and make a huge mess to do a fork oil level change?
Used factory spec 30 weight in a set of 70 forks and ouch they are harsh, need to drain and go lighter. Will prolly put 15 or 20 weight fork oil or 10-30 motor oil??? in the 70 set ready for oil now.
Hint; precoating the fork seals with DS2 powder is a no brainer good thing. smearing seals with soap (thick) lithium grease before install a good thing also.
I have an 81. My damper rod has holes ~half that size. According to what I read in the Minton mods, those have already recieved the treatment. Check the holes at the top of the rod.What do we think, drill these out or leave? Currently 4 x 5-6mm holes.

One hole or two? Read the Minton mods posted aboveThe hole at the top is 2mm
Yes, those may have been drilled already. If you do enlarge them more, I wouldn't go any bigger than the 1/4" (6.35mm) that Minton recommends. Minton calls for 2 holes using a #45 drill bit at the top ......

There is one slightly smaller hole there already and you enlarge it slightly with the #45 bit then continue drilling through, out the other side, to create a second hole. The #45 drill bit (.0820") is a hair over 2mm (2.08mm) so I suppose you could drill through and create your second hole using a 2mm bit.
The original springs aren't progressive but much shorter, I can't decide which to use now as the progressives length and lack of spacer is surely what has caused the spongey front end....well that and the fact the one fork leg had leaked nearly 1/2 it's oil out.Just remember, that fork oil level spec is with the springs out AND the forks fully compressed. Don't fill them to that level with them fully extended, that would be way too much oil in there.
Do you have the original springs and are they progressive? The stock springs on the 35mm forks are but unfortunately after all these years, many have gone soft. But adding about a 3/4" preload spacer fixes them right up. If you do switch back to the stock springs, you may need to make up a slightly longer preload spacer as well. I wouldn't make it more than an inch longer than the original though. I started out with added 1" spacers but they proved to be a bit too stiff so I shortened them to just under 3/4" (13/16"). They're pretty much just right now.
