Mikuni TM-32 fittment
« on: November 18, 2013, 09:38:56 AM »
I just ordered a Mikuni TM-32 for my 07' Electra. Someone on the list mentioned that they were available through Amazon for a good price. My bike currently has the 29mm CV carb on it. I am wondering if I can use the rubber mount that holds the 29mm CV for the TM-32 or if I need to order another Mikuni manifold from Sudco. Anybody been here, done this? I'll likely be looking for an after-market air filter. Suggestions on what works best?
TIA,
Bill N

You need the Sudco rubber manifold that fits the 32-34mm carbs, and has the right spacing for the studs. The rubber manifold that NField Gear uses for their 34mm carb kit will work.

You can use a K&N pod filter, or an Ace Air Canister will fit on there too.
You can probably guess which one I think you should use.

Another option. Ace makes an alloy intake manifold as well. If you follow the link to the yahoo group in Ace's signature and into the pictures, you find it in the folder of ace products. This is the option I plan on using.

You can even bore out the existing flange to match the 40mm OD of TM32 I think.

I don't know if this can be done to the AVL manifold. Maybe it can.
I do know that it cannot be done with an Iron Barrel manifold.

I understand what you are talking about - I bought my bike 10 years ago when I was studying and know how things are at that time. Until recently, I was running my TM34 on the stock flange from the AVL on my AVL engine. However, it a crazy tight fit and the rubber cracked after a few hundred kilometers. I have switched to the flange for the Classic 350 now. It seems to be of a tougher material and has been holding up pretty well. I don't think you should bore it out too much as these are prone to cracking under the vacuum. And if your bike/plug suddenly starts running too  lean this should be the first thing to check for cracks.

I use these on my bike as these are easy to come by here in India and can be replaced for a fraction of the cost of a sourcing a larger flange. The best would be to save up and get a perfectly matched manifold as Ace suggested.

A proper Mikuni 30-34 mm flange is about $25.  I think this model, M-VM34-200K, should do it.  http://www.nichecycle.com/ncs/index.php/frontpage-slider/carb-flange-carburetor-flange-adapters-rubber-by-mikuni.html

Right part for the job means less problems later (nasty lean condition), and more consistent performance.

Dan B,
  Thanks for the lead on the rubber flange. The price couldn't be beat and I don't think I would have found this on my own. Now I hope the jetting on the Mikuni TM-32 on order is in the ballpark. Playing the "right jet game" usually ends with a pot of brass jets. Any suggestions on starting points with jets?

              Thanks for that part #, Dan.

               I'm just about ready to pull the trigger on a TM-32 even if I don't put it on until after next year's riding season. I can't see passing one up now for $127.

                OR I might put it on right away when I get my head back  :)  rather than play with the BS-29 jets all over again & THEN go through it again with the TM.

                Can anyone give me a source & part # for the throttle cable I'll need for an '08 AVL with stock bars & levers?

On my Iron Barrel I had to grind the top of the flange flat to clear the headbrace mount.  The flange is rubber over an aluminum (aluminium) core and a grinder or cutoff wheel works fine for this.  I don't know about he AVL head though.

@Tooseevee:  Since you're sending the head to Ace, you may want to consider Ace's 32mm intake, also made at Mondello's I believe.  He can have it matched to your head!  Just an idea. 
Throttle Cable: I ordered an iron barrel cable from India.  I believe this will work, as it has the correct nipple on it for the TM32. Still waiting and havent checked the length.  I have an Electra and not the Classic (don't think that should make a huge difference as the PWK 30 uses the same IB cable), and I also changed the bars to drag bars.  I dont think I'll have a problem, but will know soon enough. Backup plan is to either order a long IB cable or just make one to fit. 

@ D the D:  Hmmm, you may be correct that the stock Mikuni flange may need to be cut down a bit to clear the AVL head steady.  Should be a fairly easy mod if needed.

@motoguzzibill:  Jetting is dependent on your conditions & setup.  I'm in Illinois; +100 sea level, its COLD at the moment and I have a 'mostly' open air intake and exhaust.  So for my initial setup I've elected the following:

Pilot - 30
Main - 200 (I have a selection: 185-200, in steps of 5)
Needle - Stock
Needle jet - P6 (Q2 is stock or as supplied)
Air Jet - Stock
Slide - Stock

If you are ordering from Sudco anyway, then get their Motion Pro cable, called "Enfield Throttle Cable" Part number 021-947.
Great throttle cable, and worth the money.
We use them on all the Fireballs with the TM32.

              I finally found Throttle Cable 021-947 for the TM-32 on a RE on the Sudco Price List. It's $22.00, Item #4,223 in a cast of millions, I guess.

              The website doesn't seem to work like most I'm used to. Most links produce a Not Found 404 when clicked on  & the online catalog is impossible to read (the text is microscopic). And there's no Search window. And there doesn't seem to be any way to order anything. Is it me? Do you have to order through a dealer?  That would make the cable what? $50.00?

I'm not sure.  I've asked the question to Sudco directly today.  If you'd like 2CV, i can order a couple of cables (if it's possible) and then you & I can work it out later.  PM me if interested.

Soon as I hear from them, I'll share what I find.

           Thanks,, Ace & DanB

           That's what I'll do when I've thoroughly convinced myself that ordering the TM is the path I want to be on.

            Why can't I just be happy with the CV? The bike runs perfectly fine, perfectly being relative, with it.

For the same reason you have the smaller battery, missing side covers, no catch can, opened the exhaust/intake --> You can't stop tinkering!! ... just like me  :o

Talked to Sudco... just call them and they will handle for you. Or you can use a local dealer to do on your behalf.

Dan's absolutely right!

Meanwhile, I have a slightly more random approach to throttle cables. I just bought a stock classic iron engine Bullet item. I then fitted a 90 degree bend ferrule to the carb top so as to direct it away from the underside of the gas tank, and simply trimmed the now over-length outer cable to suit. This was on a Dell'Orto PHF but ought to work on the TM32 Mikuni, especially as this is quite a tall carb, and room under the tank is limited.

Regards,

Adrian

The TM-32 I ordered from Amazon arrived and I thought I'd let others know that it is shipped with a 250 main, 45 pilot and a Q2 needle jet. It will be another $25 worth of jets, more if I order a few extra sizes, a cable if I can't piece one together $22, then an air filter. I may try to find a 58mm id hose that I can be used to connect the carb to the airbox.

No rush as there is a few inches of snow in my yard and the temperature just barely broke 30F.

Yes, all the TM32 carbs come jetted like that. They always need a complete set of different jets for our application.
I think the usual application is for some motocross bike.

             Because the ball end for the stock BS-29 on an AVL will not FIT the the slide lifter holder on a TM 32. You can't use the stock cable when going to a TM 32.

          I called Sudco yesterday to order a throttle cable, a 90 degree fitting for the top & a bunch of jets. They will not deal with me as a private citizen so I ordered my bunch of jets from JetRUs. Now I'm on my way to the jap bike store to have my old friend the parts guy order the cable & adjuster for me.

As for TM32 jets and settings, Bedlam's Electra-X ran very happily with those used on the C.I. engined Fireball! I'm sure they're still on Ace's web site somewhere...  ;)
