Afternoon all, on this horribly hot day.
Not good weather for a Viking crazy

Finally found the cause (I think) for my Commando wet sump issue and much nagging from 'Her in doors' about oil all over garage floor eek

It was a broken Commando non-return plunger spring, so plunger was just letting all oil through to timing case when stationary.. sigh.

I am also installing a Tri-Spark electronic ignition and re-setting timing to try and fix starting drama's

fingers crossed, full test at weekend.

Ride well

The little bucket shaped plunger works well when everything is shiney and new, but there's an upgrade which uses a ball instead that fixes wetsumping for good an' all, just in case it happens again....

I especially like it when I go to investigate an issue and find an obvious cause like a broken spring, broken tooth, burned wire, or missing bolt.

So much better than 4 hot, sweaty days of tearing a bike half way apart and thinking some minor thing was the problem, only to put it back together and the problem PERSISTS!

I am going to regret this.

And I am going to preface this with an apology for the sterytypical "bloke" comment but did you say:

Surely the garage is your domain? If so why would she be nagging? Do you moan if she leaves something messy somewhere that is her domain?

I know.

Perhaps the garage and the front parlor are coexistant in the household of the Penguin of Passion....

In 1970 I kept my Thunderbolt in our kitchen. But it was a big kitchen.

Well glad you got it sorted Howie- but as far as I know the *other* way to keep a Commando from wet sumping is to RIDE IT MORE OFTEN.

Jus sayin bro wink

you don't know Trish, she's French...

I think it may be the oily footprints leading from the garage to kitchen sink that is the issue :-)

well I would ride it more often if it would start more often.. hahaha

I will see if the tri-spark and re-timing sorts that out.

however, the non-return plunger went in fine but stayed compressed and refused to come out, in the end I had to put an airline into the small oil feed hole and after much high pressure air events the bloody thing fired out at about 1000 mile an hour and hit me in the forehead and the sping disappeared into the depths of the garage...

took 30 minutes to locate the spring and plunger.. sigh, and had a sore head...

so tomorrow I will try and polish the plunger and plunger bore to try and get a smooth run.

will keep you posted

Howie, I see your bike servicing antics are still a comedy act. Need I repeat the tale about how you glued your eyelids together whilst repairing your Harley with superglue somewhere in Denmark.

Superglue is very good for gluing skin. There are occasionally news reports about people using mistaking superglue for eye drops: off to casualty (ER)

Acetone removes superglue, so having a small bottle around is useful when using superglue to unglue fingers but I would not risk acetone in the eye wink .

It was emotional for the rest of us too. Laughter is an emotion

Oh, it was emotive all right. Bladder emptying emotion, so it was.

Wasn't that the trip where a part from a 1948 Triumph got your Harley home from Germany,?

Howie's problems with his plunger spring doing a runner reminded me of this cartoon by Spider!
I'm sure it will bring back memories of disastrous moments when things did not go as planned!

Hi Little Bro

Yes it was, and it was peeing with rain as well if remember correctly although sadly that washer also exploded whilst in Cornwall a few years back.

gearbox now rebuilt and that problem appears to have gone away.

getting final commando parts this week, so hopefully back in action soon.
