MSD ignition

I'll second the desire for one to fit with the Alton starter!

triple it ! I'd even reconfigure my coil bracket for the MSD coil (I'm currently using it for an air horn compressor and can not fit the dual coil as in the picture)

This is brilliant and THE way to go as far as cam wobbles and other inaccuracies are concerned.
Now if you could make it fit the increasingly popular Alton conversions ...

I would suspect something could be done there. Jim

Jim,

Have you seen the Ignitech unit from the Czech Republic. It is also programmable. My guess is it works with the rest of the hardware you are using with the MSD.

I have looked at it on the website but never had my hands on one so I don't know much about it. Jim

I like the Ignitech, and the company seems to be really user friendly and easy to deal with. Plus the price is reasonable. I used one on my Yamaha SRX-6 race bike and really liked it. Easily programmable from a laptop and more reliable than the original Yamaha box. They company seems more than willing to supply a unit to fit the customer's specific requirements (connectors, triggering system, etc.). I've also considered fitting one to a Norton, but so far I'm happy enough with the ARD mags I'm using that I'm not inclined to fix something that isn't broken. It is a tempting project, though.

ya know i tend to snoop around and also found dyno tests [mostly HD oriented but also vintage] showed no detectable differences so only thing that remains to test one or 2 sparks at once is claims the single sparker tend to run smoother, somehow. Electrically its a bit harder to jump spark from the flat instead of from a point so its said/reported about 15% less effective spark that jumps in reverse dual fire kits. This hobby could be never ending just sampling all the new items popping up here and there for a while at least.

If your concerned you can always run plugs that are designed for wasted spark ignitions. Double platinums have a second platinum electrode on the side electrode for that purpose. Regular platinums or Iridiums are a waste on a wasted spark ignition as you are only getting the benefit of the precious metal on one side. Jim

Those double platinums . . . . they have a lump of platinum spot welded to the both the center electrode and the ground strap, right? Not pointy. My thought, on seeing those, was that their design goal was to achieve low emission 100,000 mile longevity, as opposed to "performance" because they do not attempt to reduce resistance through electrodes with sharp points. The "U groove" iridium Denso seems to be the best offering/compromise in this respect.

When I had my P!! deadly serious dragster It was not set up for street tune at all. Backfiring advanced to start and fouling plugs with black soot, so spitting and missfiring till too much throttle in public to get constant power pull, Kinda all or nothing - till I tired some FireInjectors from JCWhitney - OH MY GAWD. Never had to learn nothing else it worked well for a newbie that didn't even
know nothing about a complex Norton. Then got 1st no name but regionally famous shop demo Combat that had worn out needles or jets or floats or oil leaks or something way over my head in '99, so tried some 4 prong platinums
and never looked back till rest of engine and tranny and forks and disc brake and fuel tank and exhaust and chain oiler leaks got to misserable even for a hick like me. I will look into the double dabbed plugs someday but mostly with next Peel hard to fire issues in mind.

Oh yeah I had an Olds Vista Curiser wagon back then and put in the FireInjector surface discharge plugs and go locally know as Kowalski d/t the blower like inhaling sounds and the right now get up and go that allowed play with Porsches up to the ton and even out handling them in tough walled in clover leafs. Pumped my nil skill ego no end so hope they come up with a modern version as may be impossible to foul and sure can ignite a wide range of fuel/oil-air mixtures.

If only Porsche had known the suspension secrets of the Oldsmobile Vista Cruiser.

Surface gap plugs are readily available. They are commonly used in boat motors.

The surface gap plug does not resist fouling or have the ability to ignite any wider mixture than any standard plug. It is the CDI type ignition that is recommended when using surface gap plugs that make them resistant to fouling.
CDI ignition has a fast rise time so the voltage does not have time to bleed off over a dirty insulator so the spark will jump the gap.

A clean surface gap plug will work with a conventional ignition if you have at least 30,000 volts available. They will foul easily with a conventional ignition because of the slow voltage rise.

The advantage of a surface gap is the lack of a side electrode to glow under heavy load with lean mixtures. A glowing side electrode will cause pre-igntion and holed pitons. That is why hot 2 strokes and supercharged 4 strokes use use them. Jim

Hi Jim, where are you on that MSD ignition .........was it Ok on your bike , before you explode your piston !!

I have still been doing some testing yet with the MSD.

I can not use the MSD on my bike since I have fuel injection which includes it's own ignition system. That is why acquiring mileage for testing has been slow. Jim

You of all people only have one? That's not right.
