Apollo RX250 running issues

Alright I have had issues getting this bike to run correctly since I got it new. I have a mikuni clone carb on it. Bike will start and run through a 1/4 throttle perfectly. but any more throttle after that and it will bog. Plug is coming out jet black. jets in the carb are 30 pilot and 95 main needle all the way leaned out. I am at 2700'. There is no air restriction I have tested that thoroughly. Also new or old plug still same issue. Changed the jets and bog is still there and I feel like I am getting too low in the main at this point and seems like I am having another issue than that?

So what else can I look at? I have changed carbs 3x and jets dozens of times with no change. Could the exhaust be clogged from running rich? stator bad? valves? I don't know where to go from here need some guidance. Like I said runs great at start and 1/4 throttle but bad after that.
