Time for another quick win I think!

During disassembly of the bike, the coils remained on the wiring loom as they were difficult to remove, but the time has come to remove them.

Each coil connector was sprayed with electrical contact cleaner and allowed to soak in before these were wiggled until they released from the coil pack

The electrical connection on the rear most coil pack had definitely suffered the most from corrosion….

… but it was salvageable with some more electrical contact cleaner and a scotch pad.

With the coil packs freed, everything was pulled together…

... and the cradle stripped down and the surface corrosion cleaned up followed by cleaning up the fittings to ensure no electrical conductivity via the mounting bolts, but good conductivity between the coil pack mounting and the earthing point for the cradle.

Once completed, the mounting fittings were used to bolt the cradle back into place…

… the coil packs cleaned up, electrical contact points rubbed clean with a scotch pad and mounted onto the cradle.

The electrical conductivity was checked with the test coil contact isolated from the cradle and found to be good.

So the HT leads were connected to the spark plugs before being threaded through and onto the correct coil pack…

… foremost to foremost, rearmost to rearmost and the remaining connection was obvious from there!

The electrical connection and covers will be done later, as access is needed for now.

As always, if you'd like further details, please see

Here is a possible scenario that could cause this:

Have you possibly rewired the headlight?
Either at the lamp connector socket itself or at intermediate connector going to the lamp?

The two lamp filaments of course have a common 'ground' - there is no way to separate that.
When wired up correctly, with the High, Low and Ground to the appropriate terminals of the bulb, you get the scenario shown on the left of the diagram below.
Current will only flow through the Low Beam or the High Beam, whichever input is active.

IF however, the Hi and Ground wires to the lamp connector were swapped, you would get the scenario on the right side of the diagram.
What would happen if this were the case is that when the Low Beam is selected, the voltage would be divided across the two filaments and current would flow through BOTH of them
(you would get lower voltage across the High Beam Filament because it has lower resistance vs the Low Beam Filament)
That would ALSO give you approximately 5V OUT on the High Beam wire, enough to make the High Beam Indicator glow
Of course both filaments would actually be on in this scenario, but both with less intensity being at ~ 1/2 voltage on each.
So it might not look that odd.

Then when you go to the High beam, you would get the full 12V across the Hi Beam Filament and to the indicator Lamp
No current would flow through the Low Beam filament in this switch position, only the high beam (& indicator)

I obviously don't know for sure whether this is your problem, however if mis-wired like this, it would certainly give you that exact symptom
Worth checking!
(Simply unplugging the headlight connector will tell you if this is possibly the problem - if the 5V goes away and the LED goes off, it is because of this scenario)

(I've drawn it two different way diagrammatically but they are both the same electrically - not sure which one might be easier for you to follow - in either illustration simply stated the High Beam wire is connected to the Ground Terminal of the Lamp and vice versa)

Motobrickers All:

I recently purchased K75S #2 from KMEV here, Including this fine but too tall saddle by Russell:

As best I can tell they can make this shape or service it but they don't currently show a K75 Saddle on the site. I gather that new this sold for, well,  a lot.  maybe 600$ with your supplied donor seat base tray.  Completed eBay auctions suggest the street price for mine is roughly $275.   So I'll ask Bricksters in the USA please for $250 plus actual shipping via USPS or UPS to your Con. USA doorstep.  supply your zip and I'll remit a shipped price within a couple days.  payment via Paypal, please.  I estimate about $280 USA

It has a few well-documented wear spots visible in the pics attached. Otherwise, it's in good condition.  Seat tray is in primo condition.  One more point:  you will need to install your existing hinge pivots etc as I needed them on mine.

Its tall for my 5'7" frame, i was on my "tippy tippy" toes --enough so I reverted to my time-tested Corbin saddle.  This is a MUCH  more comfortable long distance seat than my Corbin and habit forming. If you are 5'9" or taller this would be well suited for you and for my money better in hours 2 and after than any saddle I've tried to date.

I won't be going tonight to the Duke because of the rain.  I will do the ride tomorrow from Loblaws to Keating Channel pub.  The weekend is supposed to be nice according to the Weather Channel reports.  I hope to see you there Adam.

Thought about visiting tonight a Duke at 1225 Queen St, but weather doesn't look promising - possibility of rain until 8 PM.
But wanted to confirm tomorrow visit at Keating Channel Pub between 12 at 1 PM during main event.
I won't be going to Lowblaws parking lot at Moore, because it's not fun to cross town going there and back from Mississauga.
Tomorrow I will be using my Trident which feels very strange after spending 3 weeks on K75 and getting used to all it's qualities :).

Managed to put in new fluid and bled the front brakes last night.
