The main stand, which is commonly installed on discontinued and old motorcycles, is a useful part of lubricating the chain and attaching and detaching the rear tire. When the main stand is removed for restoration or to grease up the pivot shaft, it is often difficult to install the strong spring.
Return springs that prevent stand violence should have high tension.
When reassembling a disassembled body for restoration, it is tempting to install the big swing arm first, but doing the main stand first greatly reduces the labor required to install the spring.
Some women and small riders have difficulty with it, but looking at the main stand from a maintenance perspective, it is a very effective piece of equipment. Lubricating the chain, which is essential for chain-ridden vehicles, can be done without a racing stand, and the front wheel can easily be lifted by lifting the lower part of the engine with a jack. The main stand is equipped with a strong return spring. The spring, which pulls the stand toward the chassis when it is removed, has a very strong tension to prevent the stand from shaking or acting up while riding. The side stand also has a spring, but due to the difference in weight of the stand itself, the spring for the main stand is set up to be much stronger than the spring for the side stand.
The main stand that is paid up often stops when it hits the stopper rubber attached to the frame or muffler. If the stopper rubber is left cracked or detached, the stand will be damaged by direct contact, so it should be repaired as soon as possible when noticed. If you hear a metallic clunking sound when the stand is raised, it is often not the stopper rubber but the muffler or chassis interfering with the stand, which is a sign that the rubber has come off or is missing.
It takes foolhardiness to install the stand springs after the body is assembled.
Set the frame over the engine on the workbench and tighten the mounting bolts. This model has a diamond shape with no under pipe on the down tube, so it can be assembled in this manner. For a double cradle frame, it is best to assemble the engine on its side and the frame through the engine to prevent damage.
There are not many occasions when the main stand is removed from the frame, but it will be removed when greasing the stand pivot or restoring the entire chassis. The spring contracts and loses tension when the stand is raised, but it remains pulled even when it hits the stopper. If they are fully retracted, the stand will sway as the motorcycle body vibrates, so a certain amount of tension is applied to the stand. Therefore, a certain amount of force is required to attach and detach the stand spring. When removing the main stand spring, pull out the pivot shaft first with the spring attached, so that the spring can be removed at the same time the stand is removed.
This is also true for side stand spring removal, where the pivot bolt can be removed without pulling on the spring by first removing the pivot bolt. However, this is not the case during assembly. It is not easy to install the spring with the pivot shaft through the main stand, even if the spring is raised. A special tool for spring removal is a T-shaped spring hook with a hooked end, but it is not reliable for pulling the main stand spring. Another method is to hook the end of the spring to a screwdriver and use it as leverage to slide it onto the stand, but this is dangerous if it comes off the screwdriver when pulled hard and risks damaging the motorcycle.
