Ohh yes stainless is no good
I made one about 3ish years back out of stainless....when my bike ate the chain gaurd and fubard the clutch rod and cinch,
It's been fine but today I was out at wheels day in aldershot and the adjustment on my clutch was getting lower and lower ....until it was pretty much lever to grip biting point....
Luckily I had bought a spare genuine one back some time ago and was luckily enough able to find it and pop it in
But here's the one I made up all mushroomed on the end causing the dramatic disappearing clutch issue....
