And that will be the hardest part!
But, you are totally right, but local traffic seem blind to bikes of any description!

Thank you, now today all finally finished as much as a classic ever is!

Good question!

I have a very short snag list, just 3 things to fix, or get better, ie twist grip effort is far too high, but then it is decision time.

Keep it and actually use the thing (original goal)
Sell for a fortune.
Sell for break-even, a far more realistic outlook.
I sold the gold one far far to quickly, really should have thought longer about it.

Not really sure what the wife thinks, but local bikers round here are scary, and drivers more so.

After 4 months thought I would have a Look-In to see what has happened on here...

I will not bore you with all the ups and downs that have gone on, would run into pages, but everything sorted now. A real sroy of 3 steps forward, 2 back (and further).
The Honda is now on the button (literally) with a skip load of parts and work.

Maybe a few pics to see if anyone is awake!

After the world's longest wait for a simple bearing to arrive, it did and with some lathe work all back together. Bloody thing still rattles, so ordered a new Chinese replacement for £23 delivered, a last gasp to fix the starter.

Bike fired up awkwardly and ran very rich.

Back to basics tomorrow, valve clearances, ign timing and start again. If this fails, swopping the jets from the original carbs to the copies, and try, try, try , again.

Interesting!
I have installed new rollers, springs and cups, cheap at £17 the set and real Honda parts too.
The drive chain similarly, all new, good and tight and cost a lot more, but Honda NOS, £33.

This bush is the last bit that keeps the rollers true to the gear journal and to the crank shaft.
Should be with me for the weekend I've been promised.
Found a local company too that make replacement oem spec gaskets individually, £7 each for the side cover, bargain.

I have to admit I've found, since installing the engine and all around it that I've miss-assembled the kick starter shaft so I only have 1/2 the travel... :-[

Bit of a rollercoaster ride on the honda.
Got the carbs, now on the bike and it runs, not that well but I need to try harder on the fine tuning.
however, the starter system (electric) is giving me some jip, and that side of the engine is apart again.
Seems to me the starter gear bearing (runs on the crankshaft) is well worn, the play is about 0.5mm.

Thus, awaiting a nice oilite bush/sleeve to arrive so I can machine to size and get rid of the excessive play. I've replace everything else, so I hope this is the root of the chattering noise and the slipping of the drive to start the motor.

Job for the weekend I hope while the wife watches the GP. :)

^^Quite agree, but my wife is fluent in French so that helps.
On forums I used google translate, and that worked well considering the technical aspects involved.
Postage costs are always high, bit like buying Honda parts from the USA, often postage is 1/4 to 1/2 the item cost on top.

During Brexit (remember that?) Chambrier stopped supply to the UK of its white wall tyres, I had possibly the last pair for my BIMA.

Doing a UK bike must be heaven! Pity finding complete bikes for restoration is so hard.
I would need a set of weird sized spanners too...

Thanks Rex.
I'll check the jet sizes tomorrow and any other fitting  details, and if ok will buy a pair.
They are available in England for that money, so not a big issue.
Time will tell, fingers crossed.

The iffy carbs are bugging me, so thinking of adapting some Dellorto knock-offs to suit.
Very cheap and you can get a wide range of jets for tuning them.

Why?
Advantage is absolutely clear drillings in the bodies and they install on the very same mounting holes to the Keihin originals.
Disadvantage? A step into the unknown....
Could irritate a few on here too! :)

Could be interesting side project too.

Look good fun, esp the girder fork second one.

Hard to find parts anywhere. I found parts in several moped (a UK name for such bikes) specialists.

Here is my working 1952 BIMA by Peugeot, there were several iterations of this model and a lot of 'badge-engineering' in France too!

Hello Joe, I remember your thread start then silence..

I found Chambrier et Fils good, site is hard work, but most French ones are!
Finding anything for these light Terrots is very very hard.
I did have a short list but it went to the new owner of my Terrot MT! as I felt he would need them....

French ebay is poor for good parts, lots of knackered ones, but found a new carb in the UK!

Best to join up to the Terrot owners web site in France, bit I wish you luck.

Indeed mini, each to their own and that is good, we should keep an open mind.
Been labouring for the Head Gardener on the Estate today, so I know my place, and not a ride-on in sight.

Last part of the rebuild is coming from the USA, about the only place now where parts are available as bits drying up fast.
5 years ago parts were easy and cheap, not anymore.
I should have checked before I bought this bike..

A few posts ago it was mentioned to get parts made/cast etc using 3D printing and CAD, I ran a large design dept when working and spent a lot of time with these methods every day.

I considered using 3D printing to have made the plastic side panels, the left is a mirror of the right, so seemed a good route seeing as a pair was about £250 without the rare badges.

Quotes came back around £550 for the pair +vat etc and 3 weeks, many also wanted one real part to scan and then to print after for that.

I paid the £250 for parts, left side was £28, the rarer right side the rest. The badges on each side sell in the USA for £90 each and tend to be damaged. I bought a knackered one, cleaned it up and resin cast 6 for £25, painted them in with Humbrol paint and a steady hand.
 A pair with badges appeared on ebay for £67 3 weeks later!
Non of this is easy. ;)

The T 492 was made in '77 and '78, about 120 were made and many exported.
In the 120 were a few specials to suit different classes mainly in the USA, and some had night time event lights etc.
The 490 had a short run of 20 made with the engine (a 2 litre Ford Pinto) rad in the front, so a large slot was in the nose for cooling.
In 78 the rads were moved to each side at the rear.

Prior to the 490/492 was a series of far more serious sports racers, the most dramatic being the T212 with BDA engines and these had far more curvaceous bodies, maybe that is the type you have in mind.

My T492 has had a very varied and hard life since 78 and I spent 4 years tracking down the history that had a few surprises and some great family stories.

I found mine in a posh private garage as a roller so the chance to change engine was on the table.
Having been very 'porsche' for 32 years, the air cooled flat 6 seemed the right choice along with it's road going gearbox, the second weak link in the car, me being the first...

Doing the cars is really my bag, the bike are a very nice mini-project to do, hence my inaptitude towards them!

In case you are interested, and before mini and others shout at me:
