Carburetor Selection
08/23/21 at 05:39:18

Sorry if this is a duplicate post, I tried searching but couldn't find any topics.

I'm new to carburetors, I've done EFI tuning on vehicles so I'm familiar with fuel mapping. I'm looking to upgrade the carb/intake on my S40 (currently only has a supertrapp exhaust) and I've been a bit overwhelmed by the CV, VM, TM styles along with the different diameters for each. Is there a quick guide that shows what will fit and what will require modification?

Thanks.

If there is something that you do not like about the performance of OEM carb, then an alternative could be the solution. For a mostly stock engine (and an aftermarket exhaust is mostly stock) the CV can be adjusted to work flawlessly.

I'm extremely interested in tinkering with this platform and I'm looking for a carb with a bit of head room over stock.

This old post is a comparison of four different carbs. I did it before I developed a more robust test program but it should give you an idea of what's available and how they stack up.

This more recent post does a better test of the Keihin PWK38. It's a bargain and it runs great.

There should be plenty of pictures that show overhead clearance. The S&S Supe E provides the most overhead clearance, but it's a very difficult installation and doesn't run nearly as good as the metric mixers.

Good luck, Mike

This is exactly what I was looking for. Thanks! it sounds like the Mikuni VM will be the best bet for me.
