Is there a good page or article someone could direct me towards so I can learn how to adjust my carb? I've never messed with my carb but know it could be better. It pops on decel and has some hesitiation. I've been following these jetting threds but they are all directed towards people that have a clue as to what they are doing. I'm looking for a good beginers guide for our carbs and something that'll tell me what's what on our carbs.

"What's that?"
"It's a Yellow 99' YZ400!!"

You might be able to get some info out of these articles that someone posted on TT a while back.

Also, there's some useful info in your manual.

Between these three resources and all of the different posts (I usually read the 250f and wr426 side) I have learned quite a bit about tuning the carb - a few months ago I had no clue (and wouldn't touch it), now I am pretty confident with the basics.

And just post questions...people will help you out.
