I remembered this time to ask about an L shaped air valve when I got my new tire mounted. Cycle Gear has these special safety valves, $29.99 for a set! I drove a car in high school I bought for $50. It sure will be nice to check the air though. I also went with an E-3 240 that I got for $152 delivered from Dennis Kirk. Nobody around here can mount a mc tire larger than a 240 since the dealer went belly up. It just wasn't worth the hassle for 10 mm, especially if I needed tire service later.
