Package arrived - new ICU is mammoth sized and won't mount on stock OEM ICU location unless I build a bracket - anyone install the Alpha system or simiar and where did you mount ICU?  - may have to fabricate an "L" shaped bracket. *You can see in picture  that heat sink when mounted on stock plate sticks up above frame and probably will interfere with tank fitting on frame.  If I drill 2 holes through aluminum, it should fit but seeking to come up with a better idea.

New wiring harness is different than OEM and is also used on converting a points bike to electronic ignition - my question is on existing coil, there are 4 wires - 2 green striped and 2 black - are both green and black wires coming from the same place and can I simply pull one of each and replace with the green and black wire on new harness?  there also is a brown ground wire that attaches to frame.

Existing OEM ignition harness plugs into bean can, ICU and a 3 prong white plug that comes off main wiring harness - does the green striped and black wire go to the frame - will use voltmeter and if I get continuity between wire on harness to coil, will replace with new wires on new harness.

FWIW, Rick Jones now carries this exact same bean can with replaceable Hall sensor on end of can - apparently I found the new model before Rick had posted it on his site.  It's a slick design.

Will keep you posted as I progress with installation - was hoping it would be a "breeze" but taking time as usual!

Fabricated brackets & icu mounted.

Green black wires from new harness connected to coil.  Brown wire grounded to chassis.

Pulled plugs &  cranked & nice bright sparks both cylinders.

Tomorrow tank goes on & will let you know what happens!

You have to determine which black ire goes to the tach and keep that wire and discard the other going to the old ignition mod  
Same with the other  determine which green wire is ignition positive and keep it discard the wire going to the old mod
Then connect your new wires up with the matching remaining wires on the coil
FYI the coil is not polarity sensitive

Ken,
BMW sell a bracket to accommodate the current too big ICU.

Dont think either bracket will work on r65ls

Package came with bracket shown from euromoto but t would not fit

Holes on bracket need to be drilled horizontal so icu plug faces down

The OEM bracket fits on an 1982 R65. And th LSis just cosmetically different.

Still stumped!

Bike started right up and sounded better than ever!

Took a short ride and after about 2 minutes she conked out again!
Removed dash and looked at all connections to key switch and everything looks good.
Removed the kill switch and wires are clean.

Pulled plugs and have a very nice spark but plugs are dry.

Removed fuel bowls and fuel is present.

Carbs have been overhauled - any suggestions as to what could prevent fuel from getting from carb to the cylinder?

I've just ordered one cause I reckon the cost of the bracket plus post is less than the time it would take me to bend up my own. i ordered one of their super-heavy duty ICUs while I was at it.

I cannot think of any fuel condition that would "perform" as you describe, i reckon that in the grand tradition of such things, you have an electrical problem.


Suggestion - hot wire your ignition so that it is powered unconditionally and then try again - if it doesn't cut out chances are you have a wiring loom, connector or switch problem.

If it does cut out with hot wired ignition start proofing your ignition wiring harness, closely followed by ignition components.

I don't see how the new adapter bracket and IGN MOD can fit between the mounting boss and voltage regulator  :-/
