Tech Talk / Re: Bassani exhaust shield

Bit difficult to measure thickness as its edges are folded and I cant get the Mic in there as its too close to the pipe.

If you can push something through one hole to hold behind another hole you can measure the depth with the end of a Vernier

My guess would be 1.0 or 1.2mm, I highly doubt they used 1.5mm

Large holes like 3/8" or 10mm would mostly be made with a thick material like 1.5 because most perf is made for industrial applications.

If you really want it to look original then get a piece laser cut or go through the pain and drill a sheet, most of the work is marking out the centers

Thanks. I have a lot of photos but its hard to work out the thickness. I can get 9.5mm holes in 1.5mm thickness but i tend to think this would be too thick to fold the edges over. i might see what is out there in 5/16 or 8mm too.

On my big bore Honda XL/Maico Icu away half the shrowd and got rid of the hesitation off the bottom

What made you think to do that Baz? So does the shroud reduce the drop in pressure over the needle jet, so by you cutting it, you increased the vacuum (reduced atmosphere pressure) to eliminate a lean stumble?

thx Leith - so the "shroud" and the "slide stuffer" are one in the same then?

from the diagram i can see it suggests there would be less mixture turbulence generated by directing more of the the air flow horizontally through the throat of the carb and reduce virtiical disturbance.  Never heard of this issue before

No, the stuffer is screwed to the bottom of the slide, the shroud is an extension of the needle-jet, into the venturi.

I have 1 of those sitting here, don't fit the new mikuni slides, possibly may fit in a snowmobile slides if they are thinner walled

Can't you file it to make it fit?
