Just got off the bike....
I bypassed the smog system, checked the fuel petcock trap, its clean, removed my inline fuel filter. The bike feels exactly the same, no difference whatsoever!

So, just maybe it's not a carb issue.
Also been thinking this, but what else would cause this?
I mean at partial throttle and at lower RPM the bike behaves PERFECTLY. And with the #148 and the single washer the bike feels so much better than with any of the others so that is an indication that I am on the right track isn't it?
At 46,000 replace the needle & emoltion tube...
possably worn to hell putting the vacume all over the place
that picks the fuel up though the main jet...
And as already stated.... fuel level....
another point.... the pilot jet... it has a bearing on full throttle as it dose
not suddenly shut off after 1/4 throttle...
the same bike/model can come with diffrent jet combinations for diffrent climates
cold... big pilot / small main..
hot... small pilot / big main..
but both have about the same air/fuel ratio though out the rev range...
Its to do with starting and warm up...

I just had a quick skim through the posts, but... are you sure you're not just running too rich with the bigger main jet? You say that you don't really see an improvement with a bigger main jet, so maybe go for a smaller main, and see how it performs.
Just because you have a slip on, doesn't mean that you necessarily have hugely increased air flow. Also, you're at altitude so might need to lean it out a bit.
Morning Guys!
I didn't want this thread to die without a resolution so I thought, let me update it!
First off, Thanks for your replies during my struggles!
Guys, it turns out, I have been dumping WAAAAAY to much fuel into the carb!
I went down from the 148 main jet I had in it to 132 and ultimately, Yesterday went down to a 128 main jet. I also removed the washe I installed in the needle and removed the wire mesh wrap around the air filter.
The bike is fixed! It revs straight to 10grand for the first time since I've had it! I am so relieved!
NOW I can actually feel how my bike ACTUALLY performs! I mean it is only a 250, so you will need every drop of power that it can produce, I only ever had about 40% of it, and I'm not a featherweight...
Here she is, so happy!!!:
