(I think only you and I are still interested)

Ha! OK, we'll let Big Jim have his thread back...   ;D

Got my stepped disk turned, need to work out the 5 hole placements next. Just won a really decent magneto for this project, plus I got an email from a guy with an original ARD setup. I'll be in touch!  ;)

you guys keep talking and I might learn a thing or two
I sent my mag up to a guy in Massachusetts for a going over and to replace anything that might need
to be replaced.
He knows the ARD systems and the mags that went with them so well see
Here is the link if anyone is interested

http://www.magnetoparts.com/fmc.htm

Also just got my RS Smoothbores today 34MM. These will or might replace my 29MM Keihins that where on my 750/840 GS Suzuki
IF the RS carbs work as good as everyone says they will, I will sell the 29s for a good price.

G'Day Jim, how are you gonna put the 34mm Mikuni's on your GS750? The port castingss are way too small on a 750 head, are you going to use a later 850 or 1000 "big port" head like the one on my 1981 GS1000S? I'd be interested in the 29mm carbs mate, but don't sell em until you've got the 34's fitted. Cheers, Terry. ;D

Big Jim -

Per your previous post, I had emailed Bill. I had one email back from him; he didn't think he had anything for the ARD Fairbanks Morse conversions, and he specifically said he didn't have any mags. I inquired about converting an FM-J to clockwise rotation (he had mentioned that), but have not received a reply.  :(

I'm hoping that the sparse emails means he's busy rebuilding magnetos and doesn't have time for foolish questions...   ;D

of spark we have

Yep, I am in contact with Steve at http://www.mainelymagnetos.com/default.htm , his email is steve@mainelymagnetos.com

Steve says he has done 750 ARD mags and sent a pic of one. He has experience with all mags and can build up pretty much anything you want.

I'm going in a slightly different route than Big Jim; I have a Fairbanks Morse magneto off a stationary engine and will be mounting that on a CB550K. The mount is different than an ARD 750 (of course!), so I'm making it myself. It's about 65% done; I need to fab up a stub for the crank extension and another for the mag itself. Then I can mount the cog belt that drives it, and decide whether to enclose the belt or not.

Even using aluminum, this thing already weighs a *lot*...and the space available makes it a tight fit...I'll post a pic of the finished mount w/mag in a couple days...to Terry...   ;D

Here's a pic of the seller's mag setup...a Mk II, I believe...



The seller was nice enough to email me the instructions for installing it, too...Thank You!   ;)

Here's something interesting...I was fortunate enough to have a Forum member sell me his ARD setup...the Fairbanks-Morse mag conversion...I wanted to see how hard it would be to modify it to fit on a 550...   ::)



...Not hard at all!...   ;D  (Click to enlarge)

*All* the breaker plate screws line up; the cover screws line up; and the mag clears the case and cylinders/carbs...

It is a bolt-on...   ;)

Edit: This is definately for a CB500/550, and *not* a 750 (check the point cover screw hole location)

And here's a pic of an FM mag conversion that a caveman might have done...   ;D



Sharp eyed readers will note that the mounting plate for this FM mag is much wider than the ARD mag conversion...and mounts it farther out...Now that I have an ARD mag to compare, I can tell you that ARD milled ~1" of the "bellhousing" off of the FM magneto (the flanged mount) and drilled & tapped 4 one-quarter UNC holes for the mag to mount to the ARD plate.

I am currently investigating whether I can do the same with the FM mag(s) I have...it would make the plate a lot slimmer...and eliminate several machining operations for the drive pulleys...   ;)

G'Day Rich, nice job mate! I should have mentioned the mode ARD did to the Fairbanks Morse mag, but it does reduce the width of the whole rig, are you gonna chop yours down too? Cheers, Terry. ;D

I'll have to make up a whole new plate. The aluminum is on order now. Still trying to figure out how to chop off that bellhousing and mount the mag. Not a lot of meat on those housings.  :(

Got an assortment of sprockets and belts on order, too. Ka-Ching!!   :P

The ARD/CDI conversion mentioned/pictured above (and here, too) -



- went for US $635.99 (Approximately $747.03 CAD)  27 bids   :o

http://cgi.ebay.ca/ARD-Magneto-for-CB750_W0QQitemZ160082800561

That's a lot of $$$!!!   :P

And a BSA belt-drive ARD conversion -



- went for US $751.00

http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=290078915118

These things sold for base price of ~$265 back in the mid-seventies...

 Soon to be 3 now huh? Andy's K0 looking any better?  ;D

On another note, is there anything special about the fairbanks-morse mag that allows it to be used with the CB's? Or could you adapt (easily, for sake of argument) any "4" cylinder mag to use with a 550/750? Does it matter which way it spins?

At the risk of revealing my ignorance, since I'm still learning (for the past 57 years)  ::) , there are many different FM mags, some may not be suitable (possibly the one I want to use)...some (like the ARD) are 1"1 ratio, some are 2:1 ratio [input shaft to output/rotor shaft]..."Any" 4 cylinder engine with a cam or crank that can drive the mag (and hold it up, too) should work...As for the rotation, I don't really know...the ones I have use an "impulse" advance unit (none of the Honda conversions use it) that 'snaps' in one direction only...but since I take that off, it can be hard to tell which way the mag rotates...   :P

I really don't know if it matters which way it turns...   ???

Hopefully, Terry or big_jim will know...   ;D

Yeah...A scan of the sheet was posted here...somewhere in this thread...   :P

Edit: I just read through that instruction sheet...it appears to be for the ARD/CDI magneto, not the ARD/FM magneto...   :'(

I don't have either sheet, but the .PDF sheet refers to wires under the tank, which the ARD/FM does not need...and a "slotted timing plate", which the ARD/FM does not have...

OK!...Let the games begin...   :D

One of the ARD Fairbanks Morse magneto conversions just went up for auction on eBay...No, it's not mine...   ;D

It's item # 230093009229   End time:   Feb-25-07 18:14 PST

I may bid on it myself...but one thing I don't like - it's been chromed...   >:(

I emailed the seller about instruction sheet, parts listing, mounting screws...maybe if it goes for big $$$ we can get him to copy the paperwork for us...   :P

Two of my ARD Mk2's appear to have been further modified, the CDI's have been removed, and replaced with just a set of points and a condensor mounted inside the belt housing, thus negating the requirement for the CDI unit and the coil.

These two came off Kawasaki 900 based drag bikes in the US, and the conversion looks very professional indeed, and begs the question, did ARD make a MK3 or perhaps MK2.5 version? Fascinating............... :)

I got a reply to my question about instruction sheet, parts listing, and mounting screws -

Hello, I do not have the instruction sheet for this, but I understand that it is available online. It's pretty simple to install, and it uses the original mounting bolts (allthough I went with new stainless) thanks & good luck

I've been looking [Googling] for the SOHC4 Honda instruction/parts sheets, haven't had any luck...   :(

up date on my ARD being check out up at bills                 http://www.magnetoparts.com/index.html
Bill was going to check out all componets, replace anything that needed replacing including the housing, ( big crack at one if the flange holes)
all for less than a couple of hundred bucks. As soon as it gets back will see what it can do

Did Bill say what model magneto it was??? If he has another housing, he must know what it is...

I'm planning on building up another one for my other 550...I'd be a big help to know what tractor magneto to look for on eBay...   ;D
