    I pulled the shaft out, too. Just make sure to put that cap back on & secure it (mine had masking tale on it from the dealer) so it doesn't fall off. Throttle response seems much better after removing it.

    Nope, taking the whole shaft out, so it's smooth sailing all the way in. Just pull it out through the black plastic piece where the lever attaches to, theres a small cap that comes off to do this. Save the cap and put it back on when you're done.

    do you have to open the carb up at all? and do you have to re-jet afterwards?

    Alright, yes it can be done on a 300EX, I did it on mine. And yes you have to totally take the carb out to do the best job. There are two small screws that hold the choke plate onto the rod, and their ends are flaired so that the screws can never back out of the holes by themselves. When you go to take the screws out, metal shavings get inside of the carb, so you have to take the carb off anyway to clean it out. Also, more than likely, your going to strip the heads on those little screws too because they're made of a soft metal and are very stubborn when they come out, so those metal shavings will also end up inside the carb which you'll have to clean out. Re jetting isn't necessary as long as your running somewhat rich. If you are running on the lean side, I would suggest going up one jet size, just like if you were increasing air flow with a new filter. This is absolutly the best mod I've made to my 300, since it's free, and it adds about 1-1.5 horses throughout the powerband, so I would suggest it to almost anyone who rarely uses their choke. Just pump the throttle a couple times before you start it up to prime the carb, and it will start in almost any conditions. Hope this helps.

    300ex rules- I just re-read your post, and no you don't have to OPEN the carb up at all, its accessable from the outside, but the carb does have to be off the machine. Just thought I'd clear that up.
