Education is key to getting the best from these great parts!
In rebuilding or maintaining any older bike , using top quality original spec if not NOS parts is paramount. My only concern is that no one seems to pay much attention at the retail level with specific application of these parts. For instance , the four bushings shown are enough for two bikes, they work in unison with two more bushings made of a different density - but very few vendors sell them or acknowledge these differences , much less package them as such. The bushings here are top quality, but will perform best only if paired with an educated purchaser.
