Transmission problem

I´m driving with my SD 06 to work and in the moment I can´t shift any more if I want to shift in hi gear I must pull with hand because is to hard to do it with foot and clutch works fine.
Are you have any suggestions??

Wow that's odd. Maybe check the shifter assembly?

Is your chain really tight?

I know what was I will send pictures, now I need 1000€ to repere it
I just can say it´s bad QC from KTM
