MX Simulator

I try and install bikes from the Tmfactory racing website and I put them into my personal folder and they don't work. I have also tried deleting them from my personal and putting them into my install folder and still doesn't work. I also checked the dynos so I know what they are under. Any help would be appreciated I want to get back into sim but I really don't want to have to use stock bikes.
Thank You

I'm having the same problem. Using stock bikes is frustrating

Are you
1: Extracting the archive?
2: Looking under the right dyno?

Most bikes are under the CRF/FC450, FC/SXF250, RM125 dynos. So even if you have a Suzuki RMZ450, it might show up under the crf450(2018) dyno.
