You've read the Doc's How To ? http://www.ausmini.com/forums/viewtopic.php?t=12376

You can use your standard coil, but you'll get a better spark using a GT40R without a resistor. That's all you'll need. Good luck with the bidding - now that you've posted it here the price will double :lol:

GT40R without a resistor is meant to be 'best' but any 1.5ohm as far as I read.

Cheers,
Peter.

???? :shock: :?
And I thought I was concise- took 1 page and was to the point! :lol:
Makes more sense once you have one in your hand, though!
ps. get the D4R85 if you can, they are better suited... :wink:

I reckon after testing these a while they are better for 1275, 1098, 998 too. A few people on here with smallbores have swapped from 83 to 85 and got better low and midrange performance.

Problem with the 83 is that they have 16* dizzy advance = 32* at crank, so for 30* total when fully advanced, you are looking at -2* BTDC static (ignoring vac advance if fitted). Not so good.

The 85 has 12* advance inside, = 24" total, so static timing to get 30* total is around 6* BTDC. That's more like it. :wink:

Ah yes.

So i'll still need to modify either one to suit the supercharger. Cool.

Maybe I'll just invest in a Wolf or a Microtech...... or a modified camira computer :wink:

Oh I just teasin' :) Not sure if I ever told you - got the 85 up and running on my 1380....all good. I still have dreams about the 123 and will probably get one when I have the engine to justify it, but for now the 85 is doing the business.

Howdy,

I just picked up the D4R85 at Pick & Payless in Blacktown... LAST LAST LAST one...
I looked at every single Pulsar there... didnt bother looking at manual or auto... its from an N12 and in MINT condition :) yeah yeah!
I grabbed the coil with it, the lot for $55 ... not bad me thinks.

So, now I just have to convert it.
I know the thread in the sticky section helps... but im still lost.
Better take it to my mech mate... he's brilliant... and it doesnt cost me anything :)

Can someone tell me though, prolly Doc is best... but others will know...
If you look at this schematic... can someone point (draw) or just explain what is being changed. I dont know Docs terminology (Drive Dog, etc.)

Image

Is the circled part the only change?
Also, what is being cut off and filed?

Sorry if this should be clear... just isnt happening at the moment.
Maybe I am too excited about putting it in... :)


Thanks,
Peter.
