I just bought an 05 TRX450R. The baffle is removed, other than that it is all stock. It seems pretty new, ridden maybe 10 times, still has hairs on tires....

So the bike idles high. And cant find the screw to tweak the idle and was hoping someone had a disgram.

Also, any input as to why it might be idling high would be most appreciated. I was thinking it has something to do with the fact he took the baffling out of the stock muffler, maybe he upped the idle instead of installing the right jet? I'm not sure.

It's a black knob behind the upper motor mount, on the left side.

I see the black knob. Sort of looks like a star. But it does not turn... do you have to loosen the center screw before it will turn or something?
