has any one found a way to run a Boyer with a mity max or other eliminator? i am in the process of restoring a build i did in 1970. 64 a50 frame 70 modified engine. i originaly built this as a custom cafe bike. the old chrome work is now pretty shoddy but it will still be a neat bike. i have a mity max but i think i remember it's being shot. anyone know a way to bench test one of those with an ohm meter? how about a source for a new tech small battery? the design does not allow for a conventional battery. thanks in advance for any info. jim

Jim, I've never run a Boyer & don't run batteries, but no doubt others can help you with those questions.

On the Mity Max, I don't know if there's an accurate way to bench test 'em, but they're usually pretty durable. Some time ago, I took a brand new Mity Max & 3 used ones & with a digital multimeter, touched the leads to the various wires & charted the readings. All 3 used ones were within 1 or 2 points of the readings on the brand new one (direct out of the package & before installation on the chop) so I'm "assuming" that the old ones are still good.

Also tested an old Mini Mite by R&R, but those readings were erratic, so it's probably toast.

If you give me a couple days, will try to either find the chart or will take the readings on the Mity Max's again & post the #'s for ya. At least that way, you can compare to see if your's might still be viable.

No worries. My TR6C Métisse has an analogue Boyer, Boyer PowerBox, Boyer double ended coil and no battery. Easy starter (esp with a Mikuni that's got a proper choke!) and big fat blue sparks. Just tell Boyer what spec alternator you're running and they'll spec the rest. Sorted.

(FWIW) Digital Multimeter readings from 2 different Mity Max's, using ohms, settings 2K & 20K

Setting 2K - Mity Max #1
Touching multimeter leads to:
Black wire to Green wire = .593
Black wire to Green wire = .583
Red wire to Green wire = 1.
Red wire to Green wire = 1.
Red wire to Black wire = 1.
Green wire to Green wire = 1.176

Setting 2K - Mity Max #2
Touching multimeter leads to:
Black wire to Green wire = .585
Black wire to Green wire = .586
Red wire to Green wire = 1.
Red wire to Green wire = 1.
Red wire to Black wire = 1.
Green wire to Green wire = 1.166

Setting 20K - Mity Max #1
Touching multimeter leads to:
Black wire to Green wire = .59
Black wire to Green wire = .58
Red wire to Green wire = Readings climb up to around 19.90 then stop at 1_.
Red wire to Green wire = Same as above
Red wire to Black wire = Same as above
Green wire to Green wire = 1.17

Setting 20K - Mity Max #2
Touching mulitmeter leads to:
Black wire to Green wire = .59
Black wire to Green wire = .58
Red wire to Green wire = Readings climb up to about 19.98 then stop at 1_.
Red wire to Green wire = Same as above
Red wire to Black wire = Same as above
Green wire to Green wire = 1.17

Please remember that these were just about the same as the readings on the brand new Mity Max (now installed) HTH...

I do know some guys that run their street bikes with no battery using a capacitor instead...
I might be able to dig up the information if you really need it but I'm sure I'll have to dig deep since I've recently moved and things are still all in a mess <sigh>

Let me know,,,

thanks for the readings riff-raff. i'll sort this one out based on that and see what happens. ol'441, thanks for the input. i know how to do that and actually ran that bike for years that way with points. what i am shooting for is to hide as much as i can from view. the capacitor has to hang off the spring and is easily seen. most of the wiring is going in the frame etc. as i get a bit farther along i may post some pics. picture cannister oil bag, molded frame ciriani forks polished, xr style tank low to flat bars, custom paint etc. it was pretty much like that when i built it years ago but was my only bike at the time so i kinda rushed through the build. now i have the time to pay more attention to detail.

Ubetcha, Jim...

Have never run a Boyer. I also don't run a battery, just a Mity Max w/internal cap. There's critics of this basic system, but it's taken me on 300 mile runs with no problems & I'm sold on it.

Sounds like you've got a fun project on your hands. Here's hoping it all works out for ya! bigt
