Hello again. Today I tried to mount the rear footboard support rod as you told and is shown in parts catalog. And I have to ask again.
Are you sure that rear support rod should be inserted from left side of frame and the nut is on the right side???
Look for example at photo in Palmer's book on page 73 where the rods are shown. When I am installing the rod from the right side (another than in parts catalog) than the brake shaft lever perfectly fit on the rod and from the left side the outer primary cover also fit perfectly. When I am installing the rod from the left side the primary cover is to far from the engine and on the right side I have than big nut, and the rod is too short to install the brake shaft lever. I'm sure that my footboard support rod is not original but looks like OEM.
Can you check this on real bike? Not in parts catalog?
Moreover, when I have installed rear rod from left side of frame, the front and rear rod are from the left side of bike of the same lenght and on right side, front rod is longer than rear rod. If the rear rod is inserted to the frame from right side than each rod (front and rear) from each side of bike (left and right) has other lenght. Is it OK? I am building an bike and still do not have side bars so I can not fit it.
