hi!
looking at the sportster frame plans, was wondering what was the distance between frame centerline and engine case mount at the front?
i usually build a frame aroung the engine on the jig, i want to fabricate a jig to hold the motor level in all plane and centered in the jig!
will be using a buell engine(1999) so the frame won't have a downtube!
the jig i want to build will bolt in the motor case at the front and rear! the rear is covered in the plans but the front without using the mount plate...!
so i need centerline frame to engine case and not engine plate mount!
thanks

I measured the distance between the blue arrows on my 97 Buell engine. That distance on a tape measure is 2+5/32 inches.
The RED line is the case centerline.

This is why building a sporty is a pain in the ass if you don't know how to do mockups.

The frame pic I used to illustrate the case centreline was just that, an illustration. My Buell had no frame in the lower mount area to reference a measurement . I don't know if xphillx ever got it built. He disappeared into the ether.

did the frame for the buell, but i used the rear motor mount/swingarm pivot block on the stock buell!
sportster and buell motor offset are different and there's not much info on theses !
