The flange knuckle has a bending range of 30° in each direction. The second knuckle can be adjusted up to 55 mm.

After the engine has been installed, please fix the knuckle header to the engine. Bend the header so that it has the exact position to be fitted to the silencer. If this is done, remove the header with caution and solder the knuckles using silver solder. You now have a perfect fitted header for your model and mounting position.
