After servicing the Marzos on the Motodd and drilling an extra hole in the Racetech valves, set the original silver spring at 3 turns, 150mm air gap and took out a 15mm preload spacer and using 15wt oil the front end has been transformed. Think I might even play with the WP rear shock now, probably room for improvement after using the same setting for 34 years!!!
I don't really fuck with settings, I just ride the fuckers 8)

Mine is the same except its got 5 washers to get to a good sag distance of 35ish mm. That's with a 9.5 spring. Me at 125kg as well. We can not compare valve adjustments obviously, mines a Race Tech and yours in that NZ one.

When I get things right the bike is like it's on rails. I was a little short on sag for road at 25mm at front, back same 25mm and isn't using more than 70% of spring travel.

The beauty with the Motodd frame, it doesn't matter what the settings are they always ride like on rails ;D
If your ever in my neck of the woods you can try it out on my test track

I've bitten the bullet and gone a pair of top-line Nitrons from DAM Laverda. Like Ohlins, they are far from cheap, but are the bees knees. I figured i won't be doing any more custom builds on this bike, so I finally want to finish what i started two or three decades ago right.

Very much looking fwd to reporting back on them ...

Have you had a chance to try them out yet? My first impressions were very good, although I feel that they may be a tiny bit under-sprung for me but time will tell.

Nor tried yet - bike is still some months off. Frame work in progress at the mo. Change of springs is no drama. With slow and fast rebound plus comp damping adjustability, there's a bit to get right.
What ... leave it standard??!!

A couple of days at Collie should be a good shakedown.
