Anti Wet Sump Valve

I use an anti-sump valve with an ignition cutoff and a reed valve and a vent in the left side exhaust valve cover that goes through a check valve up to the oil tank. Works better than any other solution I've tried. I run a dry belt clutch without a hint of oil in my primary due to a blown out main seal. Draining the sump never crosses my mind anymore either. Draining the sump is not all that much fun on my Norton. The exhaust headers run under the sump plug with very little clearance and I don't like removing the headers just to drain the sump before firing up the little beast.

Is this muther sumpin horse whipped dead yet? :)
Not a bad bandaid solution eh!
 
Just gonna note that velos from the factory had an anti-sump ball valve and have been very reliable. Question, one of my bikes has a switch wired into the starter solenoid. Anyone know who sells these switches with integral electrical contacts ?
Holland Norton Works sells one just like the Velo ones. It replaces the large banjo on the back of the oil tank and is just a big ball valve. No gauze screen though.
