electronic distributor upgrade?

Hey,
Just wondering if an electronic distributor is a worthwhile upgrade for a brumby? I believe the stock ones are points based and I'm pretty sure I've read posts on here about it being a decent upgrade.
Does anything need to be modified to put one in or is it just a straight replacement?
Cheers,
Tommo.

If you can get one from a late model EA81 then its a bolt in easy swap but if you have one from an L series you will need to play around alot with it.

Do it. Any mod that gets rid of points is a good one. Now if you could just get rid of the carby...

Thanks Brumbyrunner, that's what I wanted to hear.

There's one on ebay at $50 at the moment, so if it doesn't go too much higher i'll take it.

I believe that is one of the baron's off this board.

The one I found I'm pretty sure is a guy named dave in northern nsw who I actually bought my brumby off a bit over a year ago.
Wasn't aware he'd found his way to this forum though?

It's not just a straight swap... there is some minor wiring envolved from memory and you may have to change your coil or add/remove a balast resister. Has been about 6 years since i did this though so i can't remember spacifics.

You don't have to replace the coil but you should, at least a stock electronic coil or something like an MSD Blaster, the stock coil will usually burn out if you just remove the ballast resistor.

Also if you upgrade the coil you might as well re-gap your plugs to ~1.1mm and advance timing to about 12 degrees BTDC.

is it my memory or does the EA81 not have the shaft below the drive gear and the EA82 dizzy does ?

I just spent 20 mins typing a how-to for an L-series dizzy into a brumby and when I clicked POST REPLY it disappeared, so I can't be tossed doing it again.

i'll just say it's do-able with some basic engineering skills and an hour and a half to waste.

Mine's purring like a kitten (so far anyway)

If anyone's keen I can post the details for you.

if it helps, I shoved an EA82 dizzy into an EA81 and it fits straight in, despite the shaft bit below the cog - must be cavity in there to take it. This EA82 dizzy only has one ear bolt boss anyway. Somewhere way back some1 mentioned machine something ? spare unused boss maybe, hacksaw is crude but will do the job. You got just two wires on your dizzy ? if so I think you just match the colours to the coil wires , one with yellow goes with the yelow wires at coil, the black with the black.

yer i basically needed to no where the 2 wires had to go as there was only a black one going to the points dizzy
neway ill have a look for the yellow one on the coil to match the new dizzy with

The drive gear is different from 81 to 82. I found that i had to fit the 81 drive gear onto the 82 dizzy by drilling a hole in the shaft for the roll pin in the correct position. I then had to cut one of the adjuster ear things off for clearance and move the dizzy around one tooth clockwise for correct timing.
No more flat spots!!! (except for the carby ones)
