| CanAm 400 Frame |
| This is the new CanAm frame for my son...and me |
| My son bought a CanAm 400 just because it was for sale and he passed it every week. |
| After he got it we decided it would make a good singles class racer. |
| This is my first design which had front down tubes that made it necessary to remove the motor to work on the top end. |
| The second design has removable down tubes so the motor could drop down to be worked on without being removed. |
|
|
 The rest of the top tubes |
The first tubes are in

This is the SA pivot. The outer bushings are where the frame tubes connect and the inner ones are for the SA bearings.
|
 Swing are pivot mounted in jig. |
 Ready to remove from jig. Just needs mounts for tank, seat and other small parts.
|
 The start of the swing arm. |
|
I braze the pivot joints last after the rest cools down. I used Delrin bushings and hone them in line. They run on HSS drill bushings. |
 I use RD200 rear hubs for all my bikes. I make the axle adjusters much thicker and use large diameter spacers. |
 It weighs 208 pounds with some gas in the tank.
|
 Start of new CanAm frame. Made necessary by me crashing and destroying the first frame. I changed the design slightly and used a mount that attached to the front of the head. |
 The new frame almost finished. |
 This is the new front mount. The head mounting kept cracking from vibration so I went back to my first idea but made them removable so you can work on the top end without removing the motor. It also seems to vibrate less. |
