Hey all. Ive been looking around and I know I saw it before. I bought my 05 WR450 on Dec 21, 2004. No real hard riding. Id take it out around the neighborhood two times a week Weather has been bad(break in). Went to indoor track in Washington today. First two sessions were good. My third session started going out to track and it bogs. Restart bogs again at low idle. With the choke out everything is normal. Take choke off, bog and quits. Rev up hit track off gas. Quits, etc, etc. Bike was dropped off at dealer to check out. Hopefully the warranty will cover. #2. Persons to work on bikes. The so called sales rooms and service departments. Quite high and you sometimes get the runaround. Any good ones out there that know thier stuff. I would also like to learn. Warranty is up soon.
