Hi. I've RTFM but it's NFG!
There's one valve on the top of the right (as you sit on the bike and look forwards) leg and two on top of the left leg, one in the centre and one offset.
Which is +ive and which -ive please?
Almost forgot, they're from 2003 (old I know, but they still work so can't/won't throw them away).
Thanks
