Re: 82 Suzuki GS450E Scrambler from Aus - Fork brace done, didn't screw up too bad..
Ok, so I'm doing plan B for my ignition woes, but I do plan to go back and revisit the HEI route because it should work...
I've actually had this underway for a couple of weeks but haven't said anything as I had no idea what the chances of success were, and now I know they look real good.
So, plan B:
The DS3-3C is actually for the earlier 400 twins with points, but after a long email conversation with the Dynatek guys I reckon it should work in the 450. The only difference I could see was the advance curve was slightly different, but given that the Dynatek rotor uses the stock advance weights, that won't change.
Note though that this is something I'm doing off my own bat, the Dynatek guys aren't officially saying this is compatible with the 450's at this point in time, so don't go saying I told you it was
The other issue is the 400's don't have the oil pressure switch under the signal generator plate like the 450's do, but that's turned out to be no dramas, although I will probably grind a mm or 2 off that edge of the plate:
The other issue is that the rotor is a bit shorter than the stock rotor, so my mate machined a brass spacer for me:
So it now sits in well, except the spacer's something like 0.005" too thick going by my micrometer which is binding up the advance mechanism, so I need to sand that back a bit:
I got some of the wiring started too, and to be able to continue to use the stock coils as well as the Dyna coils I had to stick some new connectors in as I can't find a source for the OEM ones anywhere. Even Vintage Connections don't have them.
These leads will take the 12v feed from the harness to the coils:
And got the connectors on the wiring from the modules:
So, what's left to do wiring wise is I need to make up a lead for the oil pressure switch as the existing one is part of the signal generator wiring.
I plan on putting some bullet connectors in up where it goes off to the gauges so I can once again return to the signal generator wiring for the HEI stuff.
Other than that, it's sand back the spacer a little and mount the coils, then I can do the static timing and it'll be ready to rock and roll...
