If he had a new bike he wouldn't be having this problem.

If the map switch is not working, the reason is not the dirtyness of the valve, but something else. I assume the switch itself or the wiring.

You can clean the valve, but you need to disassemble the cylinder first, then the valve covers (three of them) and finally the valve mechanism. Most of the garbage or sludge is in the right hand side chamber, but I don't think it influences a lot. The valve and ports inside the cylinder were relatively clean and I don't think they get very dirty anyhow.

With those hours I wouldn't bother yet about the sludge etc., but check operation of the switch and wiring.
