How Fast Should my Stock 99 SR50 Go?

I have a stock 1999 SR50 Elite. The muffler was/is not restricted and both airbox openings are open. When I got it , it ran 33mph to 35 mph with my 200 lb self.

It recently started running bad. Leaning out at full throttle and doing 28mph as it missed. When I closed the throttle a bit it slowly sped up to 33mph.

I cleaned the carb, it was really dirty inside. Popped it back on, replaced the plug with a champion 327 as I couldn't find a NGK locally. Readjusted the carb and it now runs very smooth again, no missing nothing but 33 to 35 mph.
Is this about right?

Thanks Peter

from everything I've read that sounds about right.

Do a plug chop see how your running rich/lean wise.
