I've had a lot of machines in my lifetime and this has got to be the hardest carb to get to out of any of them. I can't believe all the crap in the way. A lot of people on here say to remove the entire carb and disconnect everything to install jets. After lifting up the subframe of the bike and removing the rear shock, I found that you can leave the throttle cables in place and hot start and just pull the carb out of the intake boot and work your magic. I started to remove those pesky throttle cables, but after lots of cussing I said to hell with that. It's actually really simple now that I've calmed down and had a couple of beers. Now if my AIS removal kit will just get here! You still can't beat the nice FI like on my raptor where all you do is plug up a laptop and change your jetting. I was actually going to wait till next year for yamaha to go FI on their dirtbikes, or get a honda, but I got such a good deal on this thing I coudn't pass it up, even with with it being a PITA to get to the carb! Well this post wasn't much, but I just had to vent my frustrations somewhere because my wife doesn't seem to get it! LOL Oh and I also removed the top engine mounts so I could access the top of the carb, which is so simple it's pathetic!
