Moving & relocating Hirth coils

[ruppluver]

First you pull the recoil,recoil cup,recoil housing,
the flywheel,& then pull the stator.I will also put
new crank seals in.

Stator off & coils out.

Now,the coil wires are cut,the blue & blue with yellow
stripe. I also cut the plug wires,right where they come
through case,by the jugs.Wires have to be cut to get
everything out & moved.

These 2 black wires coming from stator,also need to
be cut by the plug.

These 2 wires,from stator,need to be lengthened &
attached to the coils.

These black wires,along with the blue wires,attach
to coils.The black wires,then hook to ignition switch.

This is where the coils will finally be located!!
It is out of the way & easy to get at,in case of
failure.When the engine is back together & set in
place,then the wiring can be finished,most wires will
need to be lengthened!!

This is a factory Sno-Jet coil mount I used when I
put the Yamaha 396 in my Sprint 44.But it's mounted
in the same place the Hirth coils will be mounted.
I know the stuff I do isn't right,BUT I do it for
ease of working on,when parts fail.

I like to move mine to but I move mine right on the front of the motor

They can be moved anywhere.I put my coils up top,that way I can use short spark plug wires,BUT the other wires have to be made longer.On my 70-399,I have them mounted on plate,under the carb.I don't like that,so this summer I will move them up top,under the hood!!!!

Put new,DOUBLE lip crank seals in.

Put the stator back in,made sure all wires were not
rubbing on crank stub.

Cleaned old paint off of recoil housing.Also cleaned
up fan blades.

Also cleaned old paint off the case.Waiting on the Yamaha
guru to come over & clean points & time.

The Yamaha guru,woodchuck,came over & cleaned the points & timed it,timing was way off.Now I can finish putting it together & paint it & put on shelf.
