I think you'd do better in the short term to just remove the cables from the RC Valve assembly, and pin the pulleys to the backplates with a couple of 5.5mm knock pins. You may need a little clutch slip in places, but it works perfectly well on a well set up 250 as a "get you out of trouble".

Frankly, you're wasting your time trying to "tune" the inlet to recover what you've lost with a failed RC Valve system. You'd be better off spending the time and effort fixing it.
