New Project(s)

This is the bike I, and my brother, learnt to ride on.

I was 9 when we received it for Christmas in 1982, 40 years ago.

We rode it at every opportunity, around the garden, in the woods, jumps, drops, spinning the rear on the gravel.

I can't remember how long we used it, several years certainly, but eventually it just "stopped running", and no-one could get it running.

Every since it's languished in the bike stores, but i intend to have a go at getting it going. If i can't get it running i fully intend to mount it in the front room!

The other project is also in that photo..... The JAPton is finally here.

Theoretically the JAPton is ready to run, apart from the kickstarter which fell off last time i tried to start it. But it also needs some tweaking.

I'm really looking forward to spending time on these bikes and i just hope that i can get some life out of them again.

More (better!) photos will follow obviously!

Good stuff

A squirt of something flammable down the inlet of the Puch and kick it over a few times. If it coughs then the problem isn't electrical.

It's been tinkered with by some of the best tinkerers we knew, all to no avail. Personally i think the exhaust has choked up.

First job will tidying up some of the rust and sourcing a workshop manual along with fresh ATF before attempting a start.

The Japton is a fine looking utensil.

On the Puch, left fork leg - is that the speedo?

Yep.

Got the kickstarter filed down a bit today, you couldn't do the clamp bolts up tight enough to prevent it wandering on the shaft. So naturally i fitted it and gave the bike a kick or few......







The stubborn thing will not tick over easily, so im going to have to play with the Monobloc fitted, and probably also check the timing. Its backfiring constantly unless the choke is fully open.

Its fitted with a BTH magneto so I also need to research them.

BUT IT RUNS!

Crank seals the most likely culprit….

You'll have to explain that further.....

Its a JAP speedway style 4-stroke single.

The plug is wetting badly so it's more likely to be poor fueling at low throttle settings. That's certainly where I'm going to be looking first.

Oh, and I've no idea how to get the video to show, if it's not showing for you. (Its not showing for me!)

Errr ... might the Puch have such seals?

Very probably.....

Given the location of Screwd's post, timing, and lack of any other clue, I assumed he was talking about the bike discussed in the post above his......

But I'll take responsibility for not actually stating clearly that my post this evening was about the JAPton.

[Screwdriver]

Skim flick, saw the Puch, didn’t read any further.

I’ve just spotted this thread, I also got a puch for Xmas in 1982,had it for a year before moving onto a ty80. My uncle bought the ouch and took it back to Holland in the car boot for my cousin, I believe it’s still in one of the farm sheds somewhere there.

Was moving the JAPton about last night, and noticed a 'bump' as I moved the steering.

I have no idea why the thing has a steering damper on, but it has. And it's nudging the tank at full left lock. I'm minded to take it off anyway, I'm pretty sure the bike doesn't need it.

Then I took a closer look...... The steering damper is held on under the tank with a little bracket, which is bolted to the frame.... THROUGH a hole that someone has drilled in the upper rail! WTF?

I'm not going to say that this is Dad's doing... the frame was mullered when he got it (ex race bike, possibly grass-tracker, cut up, widened, etc etc), so I've no idea when the hole was drilled. But to me, drilling a hole in the tubes of a cradle frame is bloody silly - am I wrong?

[Count Steer]

I suppose it depends on the size of the hole vs the size of the tube but it does seem a bit wrong. I think you can have holes in tubes without compromising the strength much as long as the holes are small and you aren't attaching something that's going to apply a lot of load at an angle. You can make quite strong, light tubes with lots of holes in.

I'll get the tank off when I get a chance (workbench, aka "temporary storage area for parts", is currently in use for something else), and get a better look.

[Skub]

I've seen similar done before,but,it's certainly not ideal.

[Taipan]

Frames do have holes drilled in them. With a captive nut inserted and a bolt into that i doubt your losing any structural integrity.

Got the seat off the JAPton last night.....

The electrics are a nightmare of complexity.....

... not! (Needs a bit of tidying though.)

Going to get the tank off soon, once the oil tank has finished draining, the oil tap itself was leaking like a sieve so I've ordered a replacement and a bit more tubing to match, along with a few other bits and bobs from feked.com. (love that company name ) . But there's nothing to stop the oil feed pipe emptying itself - so the bulk of the oil is out, just letting the last few drops drip over night. (hence the jug in the photo).

I got very lucky - I have a 2 litre jug and used it as the first 'catch-jug' when I started draining the oil - without knowing how much was in the tank....

Guess how much was in it?

This is the aforementioned steering damper...


I hadn't realised the tank was actually resting on it!

Also - the head of the fixing bolt on the for clamp was hitting the tank at full-lock.
.

I've ripped the thing off.
