any engineering advice??
So here's a summary of my project: Going to design and fabricate adjustable rearsets to modify the current ergonomic setup for my 1979 GS750L to accommodate a more comfortable riding position complimented by superbike handlebars and handlebar risers.
difficulties I've encountered so far are the fact that the footpeg assemblies are different on both sides- the right footpeg is mounted farther back than the left and the distance between the mounting bolts is longer.
the assembly is going to consist of a mounting plate that bolts into where the old footpeg assemblies were (welding assemblies onto frame isn't ideal as a proposed aftermarket part). The mounting plate has a breadboard type mounting surface for multiple mounting positions. The new mounting plate placement already places the new footpegs about four inches back, this adjustability focuses on fine adjustment. There's about 3x1.5 inches of adjustability at this point.
A subassembly will bolt onto the mounting plate via two vertical screws. This is called a subassembly because it is a smaller plate for mounting the lever and bracket for the footpeg. The footpeg mounts on a bracket because I have to allow the footpegs to fold, so I will design a ball detent and plungert spring system for this.
Levers will attach to rod end bearings/steering arms that will connect to the shift actuator. On the brake side, I will relocate the rear master cylinder to attach to the aforementioned subassembly plate to allow for safe leverage operation of the brake (the leverage of the old brake lever is gone since the footpeg is located above the brake pivot).
My MAJOR concern for this project will be the ball detent system in the folding footpeg. Not quite sure how to do it, seems like the spring plunger is attached to the base of the footpeg and the ball detent is the cylinder that acts as the axis of rotation.
*BUT*
I checked McMaster Carr for ball detents and it seems that they only carry detents with the ball detent acting on the flat surface of the cylinder...
Any help much appreciated.
I'll post pictures of the rough SolidWorks design at the end of the week.
