Well the restrictive air filter arrangement was my safe zone for a while. I thought long and hard about needles and main jets last night. Checked my air filter nylon arrangement this morning. I had 5 layers on took it down to 2 gotta have some protection from these massive desert dirt storms. That's all I did.. Rode it around blew it out some got it up to temp. PERFECTION!
The 11 tooth from 10 tooth slowed my take off just a smiggin but my last carb adjustment made up for it. A really short stretch of street from around the house that I would leap to 35 on I now leap to 40 and a lot quicker!
There is a part at full throttle where max throttle gives no more but a smiggin less than max throttle it maxes out in better words I am in my safe zone with the main jet now.

How To Tune PHBG Carburetors - MopedWiki : From here:
SO when tuning the main jet make sure to be at WOT, or you are not getting an accurate main jet reading. Start big and work your way down. If the bike is slower at WOT than at 3/4 throttle, the main is still too big. When you are really close to the perfect #, the bike will be the same speed or only slightly faster at 7/8 throttle than at WOT. This is your safe zone, be very careful when down jetting past this point.
I started up the bike a few times last night checking the idle from cold it was great! Made one observation that is not any kind of a big deal tho except to say I think its perfect!! If the motor is started and stopped a few times cold [playing around with it] it will load up rich and blow white smoke a bunch, minutely 4 stroke around idle and a 1/4 throttle blip. If started up and gingerly warmed up and used normally its absolutely flawless.
No more carb play I is done!!!! Where I am riding is an easy 6000 feet. Hope this helps some one else at my altitude one day..
While I must admit this was my first Dellorto carb jetting experience with this type of carb. I freaking totally love these carbs now they are Killer! Dellorto's are so tunable and all the parts are out there!
