I bought a 2001 warrior two weeks ago. It runs ok, but when you go from idle to WOT, it dies. If you go from idle to WOT gradually it's fine. I can also adjust the mixer on the carb and it won't die, but this makes the idle too fast. I took the bottom off the carb and sprayed some carb cleaner up into the carb, but it didn't help. Any ideas???
Also...where the swing arm bolts through the frame..right behind the front sprocket...there is a chain roller or bushing of some sort on the swing arm. Should this have a bushing, or is just a piece of plastic? It makes a loud irregular click when I'm riding. Is it a pain to change??

It sounds like you are running to lean caused by a leaking intake boot, or a lack of fuel caused by either a dirty fuel tank or carburetor.
Before you do anything, check the intake boot between the carburetor and engine for cracks. This will cause the exact problem you describe and it happens often on ALL Yamaha's, regardless of model. A intake boot will run you about 40.00
If that's not it, Check your fuel tank for contaminants. Take the fuel line loose from the tank and see how the fuel comes out. It should be a STEADY flow.
Also,take your carburetor apart and clean it by "tanking" it. A spray shot of carburetor cleaner doesn't do anything.
After tanking it, check the main nozzle [holds the main jet] and check for stopped up passage ways. Mikuni carburetors seem to be more prone to stopping up in these passage ways than the Keihins and usually the problem is there if the problem is indeed, carb. related.
Check the float bowl vent line coming from the carb. and make sure it isn't stopped up. This hose runs towards the bottom of the frame and can be easily stopped up by slinging mud.
The chain roller is made of two parts. An inner bushing[white], and an outer roller that makes contact with the chain[orange/brown].
You would be better by replacing it with a chainroller that has a ball bearing instead of the plastic bushing that comes factory. You can get these from your dealer for about 15.00
