my buddy has a 99 SRX 700, and tonight when we were out riding his secondary stuck open. He put a new belt on before we went, same belt # as the one he took off. We were riding in about a foot or so of powder. Said that his rpm's were up from what they normaly are. We stopped and changed the belt and put the old one back on and it was fine. Anybody have any idea whats going on with it. When we stopped the first time and saw that it was stuck open I picked up the back end he gave it gas, let off and it closed. Shut the hood and he went to take off it just opened back up.
