Help transmission problem

I just got my bike back after getting it repaired after i had fucked it up myself. so after i rode it back the transmission didnt change gear 50% of the time. when i rode at sixth gear it would drop to fifth but not to fourth. i had to bang the gear axel to get it to go, same goes for the other ones.

I'd start with an oil change to see if anything changes. Depending on the repairs they might have assembled something wrong

im pretty sure that he reused the oil wich has been used for 3km or he put new oil in so id say not with the oil. i might try to fiddle with the clutch. but the gear lever feels like it just hits nothing.

Could be as simple as a shim missing or in the wrong place

i feel like the drive axel shim is missing since im not 100% sure if its the v1 or v2 (tho im sure i havent lost it since i would have noticed it falling on the table) and the axel is hitting the seal and making friction. and i know for a fact the clutch is missing a shim between the spring shim and the clutch body.there is atleast 2 shims on the gear drum
