Coz whenever my stator goes it only ever seems to be the high speed stator that goes weak and drops the top rpm off! So i thought if i could monitor it and see if its dropping off then i could do summin about it before it goes completely! 200 rpm at w.o.t is about 2-3 mph for me! Makes a big difference over an hour!

I thought if the high speed stator goes you lose 2500 rpm upwards?
Anyway, the stator outputs don't really need a proper DVA (more specifically, a DVA in the mercury sense is a peak reading voltmeter, not the same as an AC voltmeter which gives RMS) - the duty cycle is high enough that any AC reading voltmeter will do - or a normal voltage gauge (of the correct range, or a 12V one and potential divider) and bridge rectifier.
The DVA is more important for the outputs from the switch boxes to the coils where the duty cycle is very low.
IMVHO, (and I ain't gonna tell you how to do it), If yer concerned about the stator I'd just make it one of the pre-race checks.
Once you've crossed the start line, even if it fails and the gauge tells you, there's sod all you can do about it.
