hi garry, pleased you like the stand, the inlet that goes on the case is a part that i cut off a scrap rb20 barrel and trimmed to make it fit into a very limited space, its got a steel plate bolted to the top which i wil be welding a pipe onto for the carb to connect to, its probably going to need a cutout in the tank, something i will be tackling later, im going to collect my custom made crank on wednesday.

as promised a picture of the crank that martin has made for me, i am very impressed with the quality, a work of art, martin does have a pair of these big webs on stock if anyone else wants one.

if you look inside the web you can see the holes martin has drilled inside the webs to help balance it

Might be an optical illusion from the camera angle, but that con-rod looks pissed, and the big end looks real skinny.

Has the rod been altered to fit through the wider webs?
