SUPPLEMENT TO INSTALL EVO-900

IMPORTANT UPDATE AND PRODUCT CHANGE

BDL items EVO-900 Series 3" Belt Drive with Outboard Support, EVO-3000 Outboard Support Retro Fit Kit and
TF-2000 have been changed.

We have eliminated the front pulley and engine shaft support and front bearing of the outboard support.
The reason for this change was due to the many aftermarket components that come together on a special
construction motorcycle, we find that a lot of these components do not allow proper alignment of the entire
motorcycle.

When using an outboard support that was intended to keep the front engine and rear transmission shafts from
moving excessively, improper alignment will cause unusual wear and premature failure of the sealed bearings.

By supporting only the rear shaft, which is all that is really needed, we have eliminated any potential problems
that mis-alignment may cause.

Be sure to follow instructions in the Installation Guide for complete installation of the drive. This
supplement is for the installation of the outboard support.

1. Install the new pressure plate and adjust the clutch

as outlined in the installation guide. The picture at
right shows 4 springs, refer to installation guide for
proper amount of springs to be used for your
application.
