Residual Pressure Valves (RPV's) -- Help!!

Thanks for the info . . . on both the switch and helmet.

I'd have to dig the helmet out, but the guys doing the inspecting are pretty astute on safety and checking the cars over.
Along with running 9 second doorslammers, they're also leading the drive toward Kingman getting it's own drag strip.
Last I heard they were about to close on a big piece of desert property for the strip.

 

I have found that a lot of drag strips are pretty lax on helmet inspections, especially in the non pro categories and I've seen guys race with buckets that would probably do more harm than good. New motorcycle helmets are better then nothing, most of the time but old fibergl*** breaks down and them splinters would hurt like hell when they imbed your noggin!
Guess we're a little off topic - Sorry
