Looks like you could do the O ring mod on the right side of the carb without removing it completely. Looks like a couple torx screws holding the cover on and that's it. Correct?

Not torx, Allen bolts.

As headhunter622 states, it is easy to do using a pick or a pair of needle nose pliers.

What year bikes are you guys working on? I would like to know how to do the o ring on my 07 without pulling everything apart, but i'm guessing that you guys are taliking about the steel frame bikes.

mine is a 2000 400 i just had to take the ignition coil off to get the side cover off the carb. From there you can see everything you need to get to for the o-ring mod. Im not sure if its any harder to get to the side of the carb on an aloy framed bike...???

No, I just did an alloy framed bike. If you use a ball end allen wrench, it is only a little difficult to remove the cover over the throttle wheel.

What size 0-ring should I buy? I do not want an entire jetting kit because I am already jetted.

I just went to the local hare store that had an asortment of O rings. The size i got was 1 centemeter (i think it was a centemeter im not fuch of a metric man....LOL) from out side to outside. They had a little ruler there to measure bolts with that i used. The o ring just rolled onto the AP timing screw kinda snug but not all that tight. I then just took a pick and streatched it around the AP linkage. The O ring costed all of 25 cents.

The mod definatley made it squirt harder I still need to mess with the timing of the AP and maybe go a little leaner of the pilot jet. I was able to load up the engine a little while I was riding it and just slightley blurping the throttle...
