TTR90EV Cutting out at higher RPM range

2006 TTR90EV

I made a video showing what is going on exactly here: What do you guys think?

Bike has great torque, but it starts cutting out in the higher RPM range as shown in the video. Greatly appreciate any ideas or things to look at. I did order a #95 main jet as it seems to be running out of fuel.

The carb was soaked for 4 hours in Berryman Carb Cleaner.
Spent two hours in heated ultrasonic cleaner.
Blew out all holes with high-pressure air hose.
Exhaust is stock inside and out.
Air box is stock inside and out
New spark plug CR6HSA
New air filter treated with oil.
Valve lash (intake and exhaust) set to factory specifications.
Float was set to manual spec (16mm if memory serves me correctly).
Jets are stock 12.5 and 90.
Fuel valve was cleaned thoroughly and I installed an inline fuel filter after the valve.

Thanks in advance for any help/suggestions/ideas.

It does sound like a main jet issue. Not sure if I have a manual on my computer, I will check tomorrow.

Welcome to the forum btw. After 5 posts I think you will then be able to post a video link.

Thanks for the welcome Morphrider.

Sure hope it is the main jet-should be here in a couple days.

Unfortunately, there was no change from #90 to #95.
