[QUOTE="davidd, post: 126197, member: 1177"] David, That is interesting. AHRMA never mentioned the core remover valve cap. However, I checked the rules today and they have eliminated all rules about tire safety. The rule used to require metal valve stem caps (I used the flat tops) and I remember one race meeting where the referee mentioned that a rider had a valve cap failure and it caused a crash. The rider was at the meeting and spoke up about it. The rule also required "a rim strap." In fact, the rule suggested the rim strap be made of duct tape, which I did not like at all, but complied with. It has all been removed. I do think a flat metal cap is the best. I had some plastic caps on the car that a tire place put on. They had a metal threaded insert. The insert welded itself to the stem and the plastic cap turned in place. I did not realize this until I was on the road and needed to top up a tire. Since then I buy metal caps from Pegasus Racing. They do what I want. 4 caps for $3, which is not free, but they are good quality. Racing organizations often change rules based upon the latest accident. ECTA used to be quite strict about chain guards being sturdy and covering the entire length of the chain, including CS sprocket. Then someone had a chain break and jam in the guard at a high rate of speed. The rule changed to make chain guard use optional. Something similar happened at Bonneville years ago. A bad accident was traced to the front tire tube overheating. After that, cast wheels with tubeless tires became mandatory in most classes. I certainly went to cast wheels. I do like metal valve stem caps as they have never been a problem. I run a core remover on the rear wheel on the street, but I often slip a rubber tube over it. It is not much use if it is not there when you go to use it. David [/QUOTE]
