It seems like this problem just happened to me today while I was out ridin. I didn't know how to explain to my friend to ask him about it but it seems like I found the problem here. I had the HPD trail pipe and clutch kit installed last week. The only question I have is could it have anything to do with the work I just had done to it? I've never had a problem with the throttle before until now and don't know what to think. However when this happened to me I did notice the oil light come on. I was running low on oil, so I filled her back up. I dont know if maybe that had something to do with it. Thanks for any replies.
