Got any pix? Did you just reuse the rubber manifold?

I just bought these filters. They look cool, and I'm hoping the offset will cure
any fitment difficulties.

offset air cleaner? Cool! I like the steadfast store. must have passed right by those. I would like to get a manifold for the carb. They are available from JRC Engineering. They are pictured with Amal carb but since this is a direct replacement for the Amal I think only longer bolts would be required.  Anyway, that offset would be just the thing without having to switch to a cone type or bellmouth.
  Oh, that manifold is I believe called a "Finned manifold" on the website.

  I can't complain about my stock carb on my 2007 Classic. My bike will almost always start with one kick, even after 2-3 weeks of sitting, and the choke can be opened right away and it sits  there nicely and idles on its own.

Birdmove. Glad to hear that you are having good times with your carb. It seems to be a mixed bag.Some have no trouble others have some. I am sure anything that arises can be cured. I just didn't feel like going through it when another carb, suggested as a worthy replacement to the Amal by JRC was available. I believe that if one does not have problems with their Mikarb then there is probably no reason to replace it ever, only upgrade the jets and floats. They are a fine carb!

Yeh, mine needs a little throttle for 20-30 seconds to stay running when cold.
But it does kick over first time, 99% of the time. Even after a couple days sitting 

Steadfast has those manifolds and I'd seriously love to use one on mine.
But looking at your pic, I'm not sure it would fit. Even with the offset filter. 
Possibly if one of the fins was milled off.

[jonapplegate]

I do have one gripe about the flatside. This is no ones fault but the choke is a pull up push down type located on the left side. Can't be reached from the left. Have to reach through from the right. I may make a new knob that reaches across to the right side.
  Shrugger, how do you mean that the manifold wont fit? I don't see it but if it won't I sure don't want to order one.

[shrugger]

I'm sure the finned manifold would fit fine with a cone filter. Might run out of
space though with the much wider pancake. 

[shrugger]

WhoOps! it's not Steadfast that has them, but this guy.

He'll sell a single for $27 Thats cheap enough, I'll buy one just to see if I
can make it work or not with the cool offset filter

[shrugger]

Alright. Got it on and running. Has enough pep now to make me smile 
Went with the 132 main and the clip is in the 3rd position. I may need to
do some tweeking as the pipe is turning gold and I have some loud
deceleration pops.
I added the chrome offset filter and it looks sweet. Plenty of room for it too.
I*'ll see about shooting some pix tomorrow.

About the only problem I have with this carb. I feel that the throttle spring
could be just a wee bit stiffer.

[ace.cafe]

Pipe turning color rapidly and loud deceleration pops mean....

LEAN!

Richen her up good, and then work it back down to where you want it.
I'd raise that needle a step richer right away. At least.

[shrugger]

Thats what I expected. Wasn't sure if it needed the next size up or the clip moved
a notch.
I'll start with the clip and see where I am from there. Thanx

[shrugger]

Now I'm at a loss 
Moved the clip down one toward the pointy end of the needle. That did
reduce the popping considerately. Still have occasional decel popping, but
it's not very loud.
The problem, at around 50 and up I've got a slight engine miss.
Don't know if it's maybe an air leak or not getting fuel?!?

Also did a full throttle plug chop. It's black as night!!! The 132 main is the
leanest included with the carb. Don't know where to go from here. Except
maybe 50 miles to my dealer

Anyway here's a pic. I modified the chrome cover to fit the K&N that came
with the kit.

I fitted a flatside carb and found that I had to have a full tank of gas to stop it from missfiring at full throttle.  If my tank was about 3/4 full, or less, it would start missfiring.  I have a 30mm Mikuni now and can achive 80MPH easily with no missfires even on reserve.

Ok, you need to do a clean plug chop at the speeds where you're getting your miss.
And make a close observation of the exact throttle position. Use some tape on the throttle housing to make a little throttle position scale, and fix some kind of pointer or mark on the throttle. Mark the tape to correspond to the pointer at various throttle positions, so you can see at a glance what throttle position you are at when it happens.
Once you know where the problem is occurring(in carburetor terms), then you can use the basic Mikuni tuning guide to determine what parts are governing the fuel mixture at that throttle opening, and take steps to remedy.
That's the only scientific way to approach this, as long as you are sure that you don't have an air leak and that your float level setting is correct. 
If you take it to the dealer, this is the process that your dealer will use to do the adjustments. They don't use magic. They have to do the same stuff that the rest of us have to do, except you get to pay them to do it.

BTW, if it is happening at 50mph in top gear, that's a pretty small throttle opening, and could be still in the range governed by the pilot circuit. You might try an enriching adjustment on the pilot screw, and see if it gets better. You might have to then increase the idle speed screw to get it to idle right.
If that fixes it, you may then be able to work that needle back where it was, and possibly get it less rich at the top end that way.
Don't get discouraged. This is what carb tuning is all about.
Once you learn this stuff, you'll be a "carb-meister", and it will never baffle you again.
You'll be able to give advice to other people then.

Ah, now thats helpfull. I couldn't figure out what the air screw was till I found
this exploded view.

And just found this very usefull tech tip for the PWK
