front fork adjuster screw and 190 tyres

I wouldn't recommend ever using a blow torch either, you'll very likely destroy the Comp adjuster, as it's sealed & has O-rings inside,

Good point, I hadn't considered that.

As you say remove the whole assembly and get it ultrasonicaly cleaned @OP beware doing this will of course drain the forks of fork oil and all that entails.
