Default Adjust pilot without T-screw or removing carb

So, I just installed my DynoJet kit and adjusted the pilot per what the engineer told me. Holy cow, that carb is a pain to remove compared to my other thumper. But, still not too bad. Well I had a low RPM stuttering issue that pointed me to a rich condition. I'm currently running a 120 main with stock pilot 2 turns out. DJ needle on 2nd clip from top at almost 6000 feet. snorkel removed. When I had the pilot 2.5 turns out (as suggested by DJ engineer) is when I had this stumbling, dying issue. I was bound and determined to adjust the pilot without removing the carb using a normal length screwdriver and found nothing about it on the forums. Here's what eventually worked for me. Keep in mind, no body panels were removed.

To adjust pilot with carb on bike:
1. Loosen hose clamps on both sides of the carb (airbox and intake manifold).
2. Remove screw in throttle cable plate, but still leave both throttle cables attached.
3. Remove head shield on header pipe (this gives you the LAST bit you need to access the pilot screw.
4. Slowly and carefully begin rotating the carb so that the bottom comes towards the header. Most tubes will begin to move out of the way and the throttle plate will stay mostly perpendicular to the ground as it hits the harness. Both cables can stay in the throttle cam.
5. Once you get the carb rotated about 30-35deg, you should be clear to stick your screwdriver over the header and in to the pilot. Turn to your fancy.
6. Rotate carb back, bolt throttle plate back on, tighten clamps, and put head shield back on.

Sorry if this is a repost, but I felt bad for people spending money on an extended pilot screw or removing a ton of junk to adjust a pilot. I know the extended screw is nice but I couldn't justify spending money on something like that when I might adjust my pilot one or twice a year for weather. Hope this helps someone!

Unfortunately, all mine were too fat to fit. Hence the normal length screwdriver.

Wow, all that just to adjust the mixture screw. Small flat-head bit works great for me and only takes seconds.

Haha well shoot, my apologies to everyone for not having a small enough flathead bit! Last time I offer up a free solution to those with marginally limited resources

I used a grinder to reduce the sze of the bit I use..... I can barely fit my fingers in but it works.

On a stock bike however, there doesn`t seem to be a difference after one turn out. At least mine is that way. I had it out almost 4 turns and it made no difference.

Just saying...

DJ kit soon

Well, the tips are particularly useful if you ride and camp up in the mountains. I've seen elevation go from 5000-10000+ in one ride. Really helps being able to crank the pilot out a little when working tricky trails. And if you only have the factory tool kit with you and forgot your little bit... :P That's when it's helpful to know there is a quick (10 mins, maybe?) way to adjust the pilot without spending any money.

I have one of these, not sure why I even bought it. Never needed it , never used it. Will it work on my carb, will it work on the wife's XT 225?
