Picking on maybe 10 or 12 HL owners for destroying the whole YZ125 C/X restoration industry is a bit of a stretch.
It would be a stretch - lucky I didn't say that. I was lamenting the four YZ125C/Xs that I know of (and however many I don't know of) that became unviable resto/rebuild projects because they'd has their seat/tank used on TT projects.
Seats are easily obtainable and a tank may set you back a couple of hundred but that doesn’t make restoring the bikes unfeasible.
I remember talking to a couple of guys a few years ago.
A US guy had just bought a tank from Aust. and was getting it posted to the US.
In the same week an Aussie guy had bought a tank in the US and was getting it sent over here.
You should be pleased to know I once destroyed a CR tank for a HL look a like in the early 90’s
It took a bit of trimming to get it looking right
