Sheet steel (swg 16), and a lot of shapping and fettling by eye on a tow bar ball I can do a 'how to' if anyone's interested.

Finding long tanks is always the bane of anyone trying to make a nice cafe racer rep, and you can just make one! how awesome

I think it looks like a flat tracker at the mo, its a good look, I can imagine it with wide bars and a tiny headlamp, knobbly tyres

Your doing a fab job with it, look forward to the end result.

hey dude ,, yeah needs a tank ,, swappsies im listening ,, what for mate ,, shape ,, would have to be cafe style ,, roundish/teardrop maybe ,,or because the frame is single tube maybe a sportster type tank ,,that might look good ,, anything with the cafe look is good by me ,, so swappsies ,, what we talking ,,

i will have at the weekend ,,

[jawathemutt]

made this and i cant decide if its wrong or right ,opinions please




what do you think?is the shape wrong ,not enough curvyness,bloody orrible or nearly right?

to my eye the pipe is too long, too high and too curvy, i feel it would look more period with the pipe crossing from left to right under the engine then coming up the right side finishing about inline with the rear spindle like the 60s motocrossers but made from straight sections with the changes of direction at the joins
a bit like this

Very interesting......so you been working on the expansion chamber eh.
Did you start with an existing chamber or is it fully fabricated??

Got to give you credit on the depth you're going into and the research involved, as you were saying other day the shape and length changes the power curve and power band. takes skills that i will never have.

With a crosser its easy you can have the expasion chamber at front but the mz is harder to include it.

With a seat unit on looks like it will finish about flush with the rear but its just the angle of the upturn, needs a little more curve to it, but as i'm sure thats harder than just typing it ...yeah good job.

Edit Glenns TM has that curvier feel to it.

I see where your going now, and i like it! the pipe looks great like a 60's 'crosser but it also looks like theres gonna be no power, the down tube is too long and has no cone.

if you could make something like these? frankly i'd just buy a pipe, the complication of designing a expansion pipe is immense.
I'm thinkin it looks like a 60's motcrosser thats been turned into a supermoto from the future, if that makes sense?
