I had a super e and it worked out great I was getting around 35-38. I switched to vm38-9, down side is that no accelerator pump. So cold starts are alittle more work, but I did pick more of a mid range throttle response. But you can play and tune it for more then super e.

I like the simplicity of the VM38-9 that I replaced my Bendix with. As I have an XLCH starting took me a good solid month to nail down a method. There isn't an accelerator pump so there's also a throttle lag which a pro could probably minimize, but a pro I'm not. The VM will require a support bracket and different intake, but it's all do-able if you've any mechanical ability at all. Air-cleaner selection is EXTREMELY limited on the 38mm Mikuni also, so if you have a favorite from the Bendix/S&S world, good luck.

there is an adaptor that clamps over the throat so any of the 3 bolt air cleaners can be bolted on. I see them on occasion on ebay.
I have one on one of my shovels with a VM 38. If you are looking besue it isn't for the HSR model carbs

I have never seen one of those 3-bolts adaptors. I have had a standard VM38-9 search on eBay for a couple of years now and none has ever come up. Can you post a pic? A manufacturer name/part number? Am interested.

i'm by and far no expert, but i can honestly say that i don't notice the lack of accelerator pump on mine. no throttle lag at all. the way the mik is designed, when you rack the throttle hard fuel will issue from the main jet via the needle jet acting like an accelerator pump until you lower the throttle valve position (cruising speed/mid range) and the needle drops back into the needle jet again lessening the fuel flow from the main jet and the needle jet. it's very well designed.

ratchet, what position is the e-clip on your jet needle? it should be in the middle slot. i changed mine to the next clip up, meaning the needle is further into the jet in an attempt to increase my mpg and i still have no throttle lag. maybe something else is happening with yours? all stock jets in yours? mixture screw properly set for your bike?

It's not much of a lag really, barely noticeable, but there in comparison to the Bendix. I'm still trying combinations on the needle and jet currently, but it does get better in small increments.
As for the adaptor getting you back to the 3-bolt air-cleaner, they exist but NOT for the 38mm. I look all the time and I've seen 1 and that was a custom job that got snatched up QUICK. I'm gonna see about having someone machine one. The K&N that comes in the VM kit is very restrictive, especially if over-oiled at all.

There are a few adapters out there to use different air cleaners on The Mikuni's. Pinion gear has videos on youtube showing an adapter he made to use a bendix air cleaner.
