what revs(typically) does the voes switch at. or what Mbar.?

sorry. on a 99 M2

The switch should close at between 170 & 205 mBar absolute - if it closes at less than this or takes higher vac to close it should be regarded as faulty. The manual calls for 5 to 6" Hg and I think my math is correct but you might want to double check - knowing my mathmatical prowess
You can also check it works by means of the dynamic ignition timing but that doesn't tell you that it is in calibration of course.

Sorry for butting in but what is this device please?

Nate.

Vacuum operated electrical switch......only found on real Buells.

It might be the ignition advance but he was only asking, like.

I started out with nothing and still got most of it left.

ok thanks chaps. had a slight missfire at just over 3k (tacho needle jumps UP a little) so thought it might be a poor contact in the switch as it swaps ignition curves.

169.3194 and 203.1833. close enough eh! thanks. i will test it out as soon as i get back from orkney/parents
