What Did You Do With Your Commando Today?

Hi. Yesterday i fitted a pair of U-Beaut new Icon rear shocks to my 1969 F/Back after 30 plus years on a set of Hagons. Finished the job, turned the rear wheel to make sure no nonsense and it turned by hand then stopped. Turned it the other way and about a 1/4 turn it comes to a soft stop! Did it a couple of times , thinking expensive gearbox damage and walked away. This morning removed joining link to wheel it onto workstand. Pulled plugs ,put it into 2nd and rotated it with kick start. Chain fell out along with 3/8 shockie flat washer! How the hell it landed on the top of the chain right on centre? Could see marks in the centre of washer where the front sprocket tooth had speared it. Why does God always laugh at me?
Leaving the pub one night a mate of mine was trying to pull away on his C15
It would move about a foot then stop
He tried it several times
Turned out a bit of rag have come out of his toolbox and dropped onto the drive chain !!🤣🤣🤣

The gods work in mysterious ways . The Gravity God at work .
Worked on the gearbox the other day and happily drove to Fergus and back . Upon return I swung out the side stand to see a small shiny thing on the pavement . It was the roller sleeve of the clutch actuating assembly . Surprisingly it had worked perfectly for the whole ride .
Off with the cover again .

I always make a slight mess emptying the oil tank into my waste oil container. This time I rigged up a neat plastic funnel and jacked up the container so it trapped the funnel nicely onto the drain hole.

I undid the drain plug, then damn well dropped it into the funnel, blocking the spout, so all the oil had nowhere to go and I had no drain plug to cut off the supply.... Spent a couple of hours cleaning up the driveway. :cool:
 
....riding along yesterday, thinking how great the bike was running, when I noticed that my Venhill featherlight clutch that I love so much, felt a bit more 'grabby' than usual, a few seconds later the red warning light briefly flicked on before the bike cut out.

Smoke coming from the battery area!!

Ignition off, seat off quickly and fuse out and I spotted the problem.

I really am such a dopey tw*t at times 😤🤬

The new battery that I had recently fitted was shorting out (live terminal against the clutch cable).

It basically melted the covering of the cable, which in turn melted anything near it.

I know it could have been so so so much worse, but I really do need to have a word with myself and start paying attention.

You are not alone!

So, pair of RGM discs with E-rings securing the collets….moving the bike heard a “ping” but nothing untoward…rode 40 miles , stopped at some lights. Went to pull away and “clunk”…bike not moving. A collet had migrated and hit a fork leg, fractured the disc and the carrier at pull away speed…how lucky was I 😮😮

I had exactly the same thing happen in 2017 and in the Isle of Man too.
I put it down to not greeting the Fairies at Fairy Bridge the day before.
My clutch cable was routed wrong of course. Pulling the fuse didn't work as the cable earthed out the battery directly. At least it gave me the chance to get a custom harness made with no joins or bullets plus using relays, some more fuses (including an earth fuse in case it happened again).
I claimed on the insurance as it was a fire.
Who did your custom harness Mark?

I was thinking of getting a harness from either TMS or AN, but a custom would be nice.

I'd love to make my own up, but it seems I can't even strap a battery in without cocking it up - and need to learn how to crimp (properly) + I have loads of other stuff going on right now.
 
Well, the easy part of putting it right arrived in the post just 24 hours after ordering - top marks to Venhill 👍

Bonzo, was this all a result of poorly routing the clutch cable then? It looks to me that it is. I just want to be sure. When I get home from holiday I plan to look at my routing to make sure it is correct. I don't have any issues, but things are pretty tight in the battery area. Les, do you have a diagram of the correct routing of the clutch cable, if one exists?

In my C15 days, I had some spanners wrapped up in a rag roll in the toolbox. Then the bike backfired through the carb, spat some buring petrol through the hole where the air filter wasnt and set fire to the rag. Never undid the two sleeve nuts so quickly.....

Re. battery, I use a Motobatt on my bike, the terminal is 'flat' - a much better arrangement than the vertical terminal. I also made a metal 'strap' (for want of a better word) and brazed it to the battery tray such that the battery can be held down with a Triumph style rubber strop and buckle.

For teflon lined cables, I have been using 'Super Lube' - a PTFE lubricant - doesnt harm the lining of the cable. A search for 'syncolon' will find the stuff. Also good for leather jacket zips without damaging the leather.

There is but it's for the central oil tank models.

I think perhaps it is not the cable that's at fault but a problem caused by modern battery posts having both top and side locations for the terminals the original Lucas PUZ5A battery didn't have so really a matter of making sure nothing can potentially short the 'live' (-) terminal/bolt.

Les, thanks for digging up (or creating) this diagram. It's quite helpful! From the looks of the routing, I routed my clutch cable similar, on the right side of the frame and down toward the trans. I don't even think that my cable enters the battery box area at all from what I can recall, but have to check when I get back. I did buy a hydraulic conversion kit from Matt at cNw a year back, but hadn't installed it yet. This is mostly because I have no idea what I'm doing with the trans, and from the adventures that Torontonian has been writing about taking his trans cover off and on and off and on, I'm not sure I'm ready to take on this new challenge/learning opportunity. Maybe over the winter I might give it a go. However, when I do get around to installing the kit I would likely route the hydraulic line the same way as I have the cable now.

For trans, buy the hemmings DVD and do what he says.

As Les suggests, I don't think the routing of the clutch cable was the issue (I simply followed the original routing and it was fine).

Before I fitted the new battery, the other one was smaller in width & length, so I could sling it to the side (the down side to it being smaller was that it would often shift with vibration). No, I installed the new battery (a Motobatt MBTX20) and this fills the tray more. I used the older battery terminals orientation with the connections to the middle of the bike, strapped it in tight, but failed to insulate the - terminal from the clutch cable (I'll use the excuse that a mate I hadn't seen for ages popped in for coffee and I did the install amidst plenty of banter & piss taking).

In short (no pun intended), I made a school boy error and wasn't paying attention. On the plus side, it's given me a kick up the bum and as mentioned could've been so much worse. It's also necessitated a rewire that I wanted to do anyway (it's 50 years old), but would've rather done it in the winter. I've taken the easy(er) route and ordered a new harness from TMS.

A long way of saying, your cable routing should be fine ;)

So, thing I omitted : the “ping” I heard was an E spring departing from the respective collet.
A latent failure source with potentially catastrophic results!! Now use Norvil discs n carriers with clear non corrosive adhesive sealant on E springs ( RTV 3145 - really good stuff)

Thanks Bonzo. I'll still like to take a look at my bike when I get back to look things over and all that since I did so much to that area of the bike with the carb rework and I did change my battery out when I installed the PODTronics module in place of the old regulator/zener setup.
 
I have one of the deluxe models that has red and black leads only (the lamp is prewired from the control box and just slides into the existing warning light housing, after removing the existing lamp and socket and wiring from the old WLA). I haven't installed it yet, but It looks like all I have to do is hook up the black lead to the white hot wire that comes from the ignition switch and the red wire to ground, all inside the headlight shell. No need to run the black wire back to the ignition switch and fiddle around with that connection. I had to custom order it from Graham since I have a Shorai LiFe battery and the stock voltage thresholds needed to be adjusted.
I like my CWL with pressure switch warning feature. Only nit pick is the requirement to run with suppressed ignition setup. 5k etc. Anyone running unsuppressed without affecting the CWL?
