I started cutting up one of my stock peanut tanks today to get it to sit further down on my top tube. Made a new tunnel out of 1 1/2" steel tubing & some sheet. I bent the tubing to match my top tube, then sliced it in half with the cut off wheel
Gonna make tabs at the front & back kinda like a whizzer tank, and run a flow tube underneath the top tube so the gas can cross over from each side. Thinking about shortening the gas filler stem too.
I'll post pics tomorrow.
This is what it looks like now, accept I put 26ers on it.
