C-Clip is in the very top/first slot of the needle and numbers on it are N82M..I also checked the needle from the parts bike carb and it has N85C on it..

I'm starting to wonder if you don't have a bad clutch side crank seal....your plug should be white as hell, and running dangerously lean with those settings!
have you noticed your tranny oil mysteriously going low?....does it smoke excessively?

Nope,not using a drop of oil (ATF Type-F) from the crank case..Just the normal 2 stroke smoke and if the seal was bad,it would be smoking white pretty good...Can't smell it either and ATF smells nasty as hell..

don't use that 48 Pilot...that's too big of a jump at once...drop the needle clip into the 2nd from top.
something's not adding up...your settings are way leaner than mine...and I run within a couple hundred feet of your elevation, and I'm running very lean.
I think a leak down test should be the next thing on your menu...something's wrong.
*EDIT*
what 2 stroke oil are you using?, and what ratio are you mixing it at?

Go easy on me,im still learning all this :-) ..
Could the reeds give the top end power issue im having or no?When I checked them,the whole top half had a nice size gap..Was big enough that I could slide a penny or dime between the reeds and cage.I already flipped them and all are nice and flat now but haven't started it yet..
I'll get the 55 jet asap but I have a question about it also..Could that give the top end power issue,running too lean?
I clearly have alot to lean and I couldn't thank you enough so far for the help man..Been wanting a KX500 for a good 20 years as its my dream bike..Now that I have it,I wanna do everything the right way down to a "T" ..
I'll also do a leak down test in the next few days just to be 100% sure..
