1942 WLC build

I thought i'd summarize my first build here for everyone who's interested.

Unfortunately i must have done something wrong and the computer killed everything
i typed for the last 20mins.
So i start over, and this time i try short posts.


Sooo, i decided to get a new project 2 years ago and i wanted it to be two-wheeld this time.
I got onto everyone's nerves here for quite some time and then found something of interest. I didn't think too long because i knew i'd buy it anyway, and bought it.

Here's what i got:

edit: the board keeps telling me my message would be too short. i don't think so?

I'm pretty sure ignition should be correct now.

My information on the carb's factory settings must have been wrong,
i just doublechecked an engine overhaul manual from '52 and it says
3 full turns for the low speed needle:
"With needle valve in this position, engine will start,
but the mixture will probably be too rich."

So that's my next try.

Waiting to hear the good news brah.
Nice build, that's a nice post war bike find, what are your plans for paint?
Thanks! It will stay as it is for now.

JAWS: had some time to fiddle with the carb yesterday, a friend came over
to help and we found that, amongst other little things, the throttle plate wasn't fully closed.... so all my earlier adjustments were futile.
In the end, after double-checking everything (valve adjustment, ingnition etc)
the bike ran pretty calm. On hot engine we turned the low speed needle in until we heard misses, and then a few clicks in the other direction until it stopped. I hope it works now!

Here's some nice pics a good friend took on his last visit:

Always amazing how much cooler a real photo looks compared to the ones my little digital camera can take...

Very cool. Keep an eye on the plugs.

That is a great looking bike. I bet in person it looks even better.
FrenZ: Von Zeit zu Zeit... ;)

JAWS: Just had a look at the plugs and they're still kind of black, but nowhere near how they looked before. So i think we're on the right way here.

Next step ist registration and then ride, ride, ride.
you gotta get a good ride in it before you can really get a good plug reading

I agree!
I was thinking about this bike the other day, and it donned on me that we never heard if it was running right.

Is it?
Funny thing, Jaws, i was just about to dig this up last night, but i forgot my
board login secret magic words and i was at home with another computer...:rolleyes:

The bike got registered on wednesday and is now officially road legal!
And it runs great! ... until yesterday evening. But i will start at the beginning:

We got the carb tuned and finally it ran very good, i was surprised the first times in the saddle because to me it felt it pulled like a freight train!
I know it's still a snail compared to OHV big twins and stuff, but for now it's
really just fine for me.
Then came the ice and snow and i couldn't really think about getting it on the road, but in the beginning of this week the weather changed and i got my plates.

I really hate it that we have to put these ugly large plates on the bikes here, but it's no use crying and at least i can finally ride!

I took it for a spin, first thing that went south was the speedo, i guess that goddamn speedo drive in the rear drum disintegrated. i really hate that construction.
Second thing was the rear plug, it started running real rough and lost most of its power, and when i checked i found the rear cylinder quit work. changed the plug and i was good to go again. Strange, though...

I rode for a while and grinned and ate some dirt (running without a front fender is new to me, but i think i can get used to that:rolleyes:) and afterwards put it back into the garage and fixed some minor things.
Then, in the evening, i wanted to ride it again in the dark to check the lights, because i thought i had noticed the front light going dark from time to time on low idle. But, when i kicked it, this happened:

Serious amount of oil spilled out of the cam housing breather valve!
The oil tank is nearly empty now!

I guess some valve in the feed pump is stuck, and the crank housing got flooded...?
What to do?
I think i read something about similar events somewhere here on the board, guess i'll go use the search tool now.

Fred, great job. You should be very proud. That bike looks amazing! About the oil leak, place a cake pan under it for now. The more you ride it, the less that will happen. You could try seating the ball bearing, although I've never had much luck with that. Bon chance!
Thanks, Phil!

So you really think i should just refill the oil tank and crank it up?
The check ball needs seated, really common. He's right the more you ride it the better it will be, but if it sits.....puke.

Keep and eye on the oil bag.

There are lots of ways to seat that check ball. I'm sure you can find a way you like.

Fouling plugs and tuning go hand in hand. Great work!!!
Ace ride
Seat from the front looks like a crocodiles jaw closed .
I had on off problems with my ULH dumping oil(over 10 years),mainly after it was stood a few weeks in a warm garage, level in tank made a difference but i fitted an inline filter which has a check valve, this solved the problem, but bike is being used most days.First time it happened i was horror struck:eek:
thanks guys!

Jaws: good to know about the plugs... never had that before.
guess i go get me a pack of spares...

Richbob: good eyes there, it DOES sorta look like an alligator...:eek:
and i was horror struck indeed, because before i got the engine rebuilt it was leaking as well when it sat for a few days, but nothing in comparison to that spill!

the pic where it sits with the puddle underneath, that was just one or two kicks, it didn't even run! and it sat for like 3 or 4 hours the most since i last rode it. i talked to my engine builder and he too thought it wasn't normal, so he told me to check if the bilge pump was working.
i did, here's some crappy footage:
hightech hillbilly test rig! :D

but it seems to work fine, and after i filled another 2 litres or so into the oil tank it stopped puking and ran like before. made quite a mess until then, though.

i must say i really don't get it yet, but we'll see.
both pumps were part of the overhaul and are rebuilt with fine parts,
i trust that man and i know he did well.

i'll start i again on monday or maybe tomorrow and see if it starts puking again.

I know on the big twins, my shovels for sure, that the check ball in the pump if not seated will sump just like that. And will puke oil out the breather as well until clear. Next time it sits and the ball isn't seated, again with the oil spill.

I made a tool and it has served me and whomever has it now well...

Ill make another.

I cant say for sure your 45 has the same design pump check valve. I assume it has some sort of anti-sumping drain back valve thing.
So you really think i should just refill the oil tank and crank it up?
NO! Dont refill the tank yet. just crank it up and run it for a while and then refill the oil tank as necessary.
