2001 GTX slows down at full throttle

[Domant]

Hi everyone, I’m hoping to find some help with my 951 gtx. When I’m riding and depress the throttle more than around 75-80% instead of speeding up it slows down. I went through the fuel system last year, cleaned and rebuilt carbs, replaced fuel lines and filters, all that stuff. I’ve read some stuff about tps sensors acting up past 80% throttle. Can anyone offer some insight? If it ends up being a carb tune up I’ll likely bring it in to a shop, as I’m not very good setting carbs (I left the settings the way they were when I rebuilt). Thanks for any info
