Well after probably a year of sitting, me and my sister tried to get her 450r up and running. Last time we rode it, I could not get it started and quickly cleaned the carb and got it running. It didn't run right so I figured the carb needed a more thorough cleaning.

Took it out today, I cleaned the carb well ( I beleive). It started up second kick and idled great. It would rev up fine, but when I would punch it or get on it at all while riding it, it would immediately bog down and then rev back up.

It seems like its running lean, not getting enough fuel.. Think its still clogged up somewhere in the carb? Has anybody had to rejet because of the weather?

BTW, everything is stock. Airbox, exhaust, jetting....

HOW BOUT THE AIR FILTER? CHECK ALL AND I MEAN ALL THE ELECTRICAL CONNECTORS INCLUDING SPARK PLUG WIRE.

atleast check it, my 400ex had that problem once and it was not getting full fuel flow.
