The reason why the motorcycle chain becomes extremely loose and cannot be adjusted tightly is because
Long-term high-speed chain rotation, due to the pulling force of the transmission force and the friction between itself and dust, etc., the chain and gears are worn, causing the gap to increase and the chain to become loose. Even adjusting within a certain original adjustable range cannot solve the problem.
If the chain rotates at high speed for a long time, the chain will deform, lengthen, or twist under the action of tension.
The first solution is to remove the joint card from the chain joint, put the removed chain at the rivet head at the back, polish one or two sections according to the situation, push the distance between the motorcycle’s rear axle and the gear box, and re-fit the chain joint. , install the chain, adjust the rear axle adjustment screw to tighten the chain to the appropriate tension.
The second solution is for chains that have been severely worn or deformed and twisted. Even if the above measures are taken, the noise will increase and the chain will easily fall off again during driving. The chain or gear needs to be replaced, or both. Completely solve existing
problems.
