I did a search but couldnt find anything like this on there. I have an 08 YZ450F pretty much all stock 40 hours on it. I bought it used a couple months ago and it started 1 kick maybe 2 every time. The other day I did some maintenance on it: New Twin Air Filter New Spark Plug Change Oil/Filter and thats it. Now bike takes forever to kick and you have to do a couple things to get it to go. No choke, throttle cracked and sometimes hot start pulled in. After it starts you have to pull the choke to keep it going. Once its hot and been running a while it starts back up 1 maybe 2 kicks. What could it be? Any thoughts? Jetting is stock.
