Purchased a 2007 450F last summer and put about 10 hours on it. On its last ride, it started to act like it was out of fuel. I pulled over, checked gas tank and it had plenty. tried to kickstart it a bunch and it wouldnt start. walked it back to the car and let it cool down.(it was a hot hot summer day). Once it was cooled down, i tried to kick it over again and it started just fine. I quickly loaded it on the trailer and took it home. Next weekend it wouldnt start and hasnt started since.
I will also say that it is most likely in need of a valve clearance adjustment. I am unsure if I should try to readjust valve clearance(wait for new shims to arrive) or try to get the bike to start and running properly before i do the adjustment. opinions?
so i was thinking this
1.) take airfilter off, spray some starting fluid and see if it will run and how long. If it runs, then I have spark.
2.) if doesnt run, then ill check spark at the plug.
3.) If runs, but eventually dies, then ill check to make sure fuel valve still works.
4.) If fuel valve works, then it has to be something in the carb. tear carb and clean everything.
5.) If running fine now, then let it cool down and work on the valve adjustment. (can someone validate its .10-.15mm intake, and .20-.25mm exhaust)
anything im missing or should look at?
