250 ETZ steering stem question.
i bought a bottom yoke with stem attached to make into a top yoke for my cafe racer. I cut and removed the stem, and opened up the hole by 5 thou to fit over my original stem. No problem. However when I started to modify my bottom yoke in the same way, removing metal from the webs, I noticed that my stem is a lot thicker than the one I removed from the new bottom yoke. Mine is 4.6 mm wall thickness, the other one is 2.3 mm wall thickness. Thread on the end is also different.
my bike is 1983. Anyone know what bike or year the other stem is? Maybe from a 125?
Quite a difference in weight, which is my concern for the cafe racer.
any info appreciated
