1996 Yz 80 Bogging

I just put a new piston in and personally rode the bike for the first time today. First and second gear are especially bad, the bike doesnt die but in the lower gears it never hits the powerband and it just feels week. Earlier today the top gears were running great besides the iffy 3rd, but now it feels boggy up top as well. There is no good power except when you hit it hard in 4th and 5th and then it pulls, hard. I know these are tough questions when you arent physically here to ride and listen to it but I dont have any experience messing with jetting. So my question at this point is, what the heck do I do!? Thanks for all replies!

P.s. I posted this on technical but no one replied.

Power valve sticking ?

Idk if it has one tho
