DIMENSION

Measure 16″ from front of neck to backbone and mark for cut

1982-1991 Models

• Measure hardtail from motor mount to the end of the frame (not the end of the slug).

• Transfer that measurement to the stock frame and make your cutin that location.

1992-2003 Models

• Measure 2 3 / 8″ back from the back edge of the rear cross bracket and make cut marks

• Cut behind your mark and sand to ensure a flat mating surface

• Use cardstock with square edges and wrap tube to ensure a square cut line

• Drill 21/64″ holes for plug welds 1/2″ in from end of tube
• Bevel end of tubing and barrel sand inner area. (Do these steps for backbone and lower frame tubes)

• Keep small gap to be sure weld penetrates the frame slug and both sides of tube.

• Leave a small gap between beveled ends to let the weld penetrate the slug as well as the tubing

• Use a clamp to bring frame sections together. Build a temporary jig as shown, or install engine to be sure placement is correct before welding
