Question about my WR450.

Recommended Posts

I recently bought a 2009 wr 450 f , the bike came pretty lean from the factory , i had the carb richened up and it seemed to run alot better ,Fired the bike up last night let it warm and i noticed at low throttle it was surging and popping and when i shut it down it made a pop out of the exhaust ,Has any one had similar problems or any ideas ,should i change the factory jets

Thanks

I am by no means an experienced rider / maintainer... but have read up a lot on my bike ('99 WR400) and been thru most of the info I could find on this site.

Hope this helps! Enjoy the new set of wheels, I wish I could affort a shiny new one🤣 but I still love the old dirty beast I got... a new one would be more machine than I could likely handle anyhow! 👍
