Last Saturday, after hitting up some trials and off road riding, I loaded up my 450F and took it to the local track, after about 5 or so laps, anything past 3/4 throttle would bog and kill the bike out, it ran strong in low-mid power, but the top end would just bog! We cleaned the air filter, checked oil, antifreeze, pulled the carb out and gave the throttle a twist and it was squirting gas out, so the bikes getting gas. Think this is a carb, accelerator pump, spark plug problem? Anybody have any ideas what this might be? Or if this has happened to them. Btw, no the choke wasnt on when I was riding!
