So I'm drooling over the polished alloy cafe seat and depressed that its so far out of my budget...
So I'm trying to make one. The only way I could think of is to find a gas tank and cut a cowl out of it and modify the seat pan to fit.
An ATV gas tank from the scrap yard looked like it would work so I brought it home and scoped out the situation..
Used some tape for a rough outline to cut.
dry fit on seat pan.
After seatpan modification. Also had to adjust the sub frame to fit as well.
