250-500cc 09 300

Had an 09 WR 300 for about a year only problems I have found is starting and seems to stall a little easy. Will a flywheel weight help this or do I need to do something esle. I love everything else about the bike, but need to get this figured out to quit thinking about those darn orange bikes I came off of!

You need to look at your jetting

+1. You can ride these things like a tractor if you have your jetting right!

I swapped out my carb for a pre jetted kehin and the bike purrrrrsss now.

Probably the pilot is too rich, I'd at least start there.

I agree that it is most likey a jetting issue. I also have an 09 300. I swapped the carb to a Keihin pwk 38 and it is worth every penny. I was jousted off my bike by a fallen tree the other day and flipped over backwards and upside down. My bike didn't stall As I was rolling around in immense pain, my friend rolled up and said "Your bike is still running...That is amazing...I can't believe your bike is still running" True story. With the proper jetting the motor will run to an extremely low rpm without stalling.

Mine is exactly the same.

What is your current jetting?
