No tuning parts after combining 2 add on vehicles?

bur587

I combined 2 bikes but for some reason the tuning isnt working. I dont even have engine upgrades available for the 2 addons I combined.

If you want to see how I combined them this is how I did it: https://easyupload.io/l0tbqi

Can anyone please tell me if I did it right? I have no idea where I even went wrong with the upgrades / tuning

Possibly a modkit ID conflict (two or more vehicles using the same carcols/carvariations modkit ID number/s) or something wrong in your 'carcols.meta' or 'carvariations.meta' files.

ModKit ID Conflict (diagnosis):
In 'carvariations.meta', set this for both the bikes:

      <kits>
        <Item>0_bike_modkit</Item>
      </kits>

If you get your engine upgrades back after doing that you have a modkit ID conflict.
Unfortunately, due to the way Rockstar did ModkitID's the best approach I know of is to change the numbers until you find one/s that work. Can be a right pain in the hoop if you have lots of add-on vehicles .

See more info & the basics of fixing a modlit ID conflict here.

If you rule out a modkiID conflict, upload the entire 'dlc.rpf' somewhere & I'll download it & take a look
