Have had my 28SE for a week now and I love it. Partly of course because of the adjustable suspension, however I recently found that the compression adjusters on the forks and rear reservoir are seized! Hardly adjustable now are they? Is it possible to pull the adjuster to bits and try clean out the rust (I'm assuming it's rusted into it's current position), or should I just get some new parts? Or just get new Ohlin's front and rear
Are you sure it's siezed from rust and not just hard against one of it's end stops? _________________ MC21SP Plaything

And just so you don't try and adjust something you can't... they are 'rebound' adjusters, not compression adjusters. The MC28 SE/SP is only adjustable for preload and rebound. _________________ Andy.

Actually, the MC28 SP forks do have comp adjustment. It's built into the rebound adjuster. So when you twiddle the funky blue knobs it affects both rebound and comp.
I've taken these fork caps off Tom to try my luck in getting these adjusters unseized.
The adjusters seem about half way in their range, so they are probably not tight against the stoppers.
I suspect some corrosion between the alloy and the brass components. I have tried GT85 spray, mild heat and a soaking in an ultra sonic cleaner but they are still fast.
An impact driver has been sugested by an engineering mate but this seems too much for the brass bits.
I Have just stripped a set of mc28sp forks with the same problem, as you suggested the alloy part had corroded and caused the adjuster to seize.
I took the fork cap off, took the adjuster apart and cleaned the corrosion in the adjuster hole with wet and dry. Definetely wouldnt hit it with an impact driver, once you have the cap out you can grip the brass adjuster in a vice and wind it out, their is a little ball bearing retained by a spring which you have to remove first though.

Not sure "far" is quite the phrase, but yes they are allegedly the best.
But the "the OOTB fully HRC ready PGM" is matched at peak (and slaughtered in the midrange) by a stock wirespliced PGM-II.
Same bike, same motor, same carbs, same jets, just the loom, PGM and flywheel swapped.
