Terrot MT 1, 100cc 2 stroke: non-starter!

[Terrotmt1]

New piston on order from Chambrier with new rings etc.
Will be rebored to suit:

Question:
What clearance would you all recommend between piston and barrel?

Also brand new points and heel from Pieceallumage.fr

[iansoady]

..... just push it down a big hill.....

.... or off a high cliff.....

[mini-me]

Set light to it, and sell tickets to all your "fans" on here to watch it burn, that should recoup some of the cost.

Incidentally, I think I know who made you that offer earlier, he meant £1.70, not 1700.

[Terrotmt1]

Might be worth £1700 or 1700 Euro when it runs a dream.
It was a French man who fancied it (as it stands).
It will owe me £3000 soon....

[mini-me]

 I think that Frenchman was bluffing, or a wind up.

Without original Carte Grise he'll have bugger all chance of getting it registered in France, especially as a import.

The reason why so much of this old french tat is coming over here via various auto jumble chancers' vans is because their govt has clamped down on the issue of the CG and its virtually impossible to get a new one. They want documents from the original dealer or factory to ID the thing, no chance.
Their bureaucracy is a nightmare regarding such things.

Even if you can get new docs you are often restricted to riding the thing to  a radius of a specific distance from your home.

If it owes you 3k, and you have been offered 1700 why did you not take it rather than throw money at it?

Then again, ownership of German cars does signify a certain tendency to masochism...............

Ve haf vays ov taking your money...

[Terrotmt1]

Ha!
You always make me smile!
Why do I do these things is beyond me at times.
Having restored and sold well the Lambretta and the Honda CB 175 Super Sport bike, I thought I would chance this one. Thought it might be tricky....

A bad choice, but I like these tech challenges though this one is more than I bargained for.
Engine all apart again waiting the new parts.

Looking at the new rings I fitted, they are very poor, really not very circular when slipped into the bore.
The NOS piston and rings in a fresh bore will be factory quality.

As to German cars, an acquired taste for sure.

One I acquired many years ago.

I realise that this bike is your interest but the trick is knowing when to stop chucking money at it. Not unusual for sellers to advertise Bantams etc for £2000 when it stands them in at £3000.

As to German cars, an acquired taste for sure.

Like hair shirts and self flagellation?

I have  occasional amusement getting people to google "unsold new motorcars". Its astounding how many new cars are sitting unsold on airfields and other sites. BMW have a facility for stripping the damn things down again.

They can't stop producing cars so they end up with a huge glut, meanwhile mugs pay way over the odds because they think they are buying quality or status.

Back in the 1980s I had to chauffeur around my employer in an Audi 100CD, it was shite through and through. Minimal resale value, hugely expensive to repair. How many of those do you see around?

Good luck with the piston, when its all been replaced repaired or modified and still won't go, whats next?

Semtex?

[TGR90B]

Self flagellation? what, with your knee?

[mini-me]

 I do it by proxy, I tell the wife where to hit me.

Knee is coming along fine thanks,far better than expected.
I have a load of women therapists bossing me around.


Nice

[Rex]

 I do it by proxy, I tell the wife where to hit me.

And then she won't, and that's what really hurts..

[Terrotmt1]

Just to ease you all back to more pressing things!

The piston is on it's way from France at great expense, and I'll have a bore to re-bore.

What clearance would be appropriate?
I was going to tell Villliers Services to bore it like it was a Villiers 4E (98cc 2 stroke, same era).
Should be ok?

[TGR90B]

Surely you send the piston to whoever is doing the rebore.

[cardan]

Often there's a recommended clearance from the piston manufacturer. If not, Villiers clearance would be a guide. If someone tells you less than 2.5 thou, or more than 4, I'd double check.

[mini-me]

If its an Indian made piston, about 3/8 inch judging from other sites
