Mount the tire in the frame and center it by looking down the backbone of the frame. I used 
a 250x18 Avon rear tire and mounted it on a 60-spoke 18x8-1/2” wheel from DNA Specialties. 
This tire is plenty wide enough and really looks sharp mounted on this wheel.

Set the axle about-centered in the axle slots in the frame. That will give you the room you need 
to go forward or backward with fender spacing. 

Since I couldn’t use a belt with the 250 Avon in this frame, I had to change the transmission over to a chain 
drive. A very easy thing to do if you know the right part numbers to get.

Place the tranny on a block of wood so as not to damage 
the stud threads then remove the lock plate bolts. Remove 
the lock ring.

Then, using a Jim’s transmission nut tool, remove the nut and 
then the pulley. Set it aside; you may have a use for it later.

If you are going to use a BDL open belt 
primary setup, you will need to remove 
the inner primary bearing sleeve on the 
transmission main shaft with the special 
Jim’s tool. The primary system already 
has a sealed bearinginstalled in the 
primary plate. If you are going to use a 
closed Harley-type oiled primary chain 
system, you’ll need to leave this race on 
the shaft.

Now remove the pulley spacer and 
the seal.
