Saffa Build
« on: April 02, 2020, 02:19:19 pm »
Good day Gents.
Acquired a BSA C11 crate project last year and with Corona doing me the favor of allowing me to stay home for a few days, i have decided to start the big task of unpacking and "dry-fit" assembly prior to rub-down and spray.
Motor is in one piece but that's about all not been fiddled and butchered. Will update you as I go. any and all suggestions will be appreciated.

Good day Louis, and welcome to the forum....if corona ends up in S.A. as it is in UK, I think you may be home for more than a few days :(....unless you are an essential worker?
Dry build first is definitely the way to go, as you will quickly sort any problems and find what may be missing etc
You will get all the help you may need from this site full of knowledgeably, sometimes grumpy, but generally helpful souls ;)

Hi Louis, Welcome to the site. Let the fun begin :)
What year is your C11? Do you have all the tinware?

Is that a 3 speed frame modified for a 4 speed box like what has been mentioned on here previously  ??

Like Pete asks, if you have all the tinware, you are home and dry....as some of it is like hens teeth.
Do you intend to keep it as original as possible, or going to "personalise" it any way.

Good day Gents.

Thanks for the welcome to the site. Lets see if I can answer as far as I can.
I will add the bike to the register as soon as I have made the post. Please see attached the furthest back i could go with documentation on the bike. It was bought by a gentleman in 1991 with the engine, frame and gearbox as it sits today. I am unsure if this is original or fiddled with.

I do not have any of the badges i need. I was hoping to get them imported to SA along with the rubbers at some stage in the not to distant future. Will ask your opinion and guidance when the time comes.

As for the year, I have just downloaded and printed the PDF doc, will study and give feedback ASAP

The idea for the bike will be green(soft avocado) and white(Pepper white) with a black pinstripe AT THIS STAGE. I am unsure if this will "look right" when its done. and will adjust as I go. Not very keen on restoring to factory spec original. I will be doing all the body and spray-work myself and plan to throw down at least 4 layers of base-coat to get where I want to be. will do the front or rear fender as a sample and take it from there.

So going by the docs, a 1948 ZC11 with an XC10 frame, interesting as it's definitely not as early as 1948 (although the engine could be). Is that a four speed gearbox also? I'm sure someone on here will get to the bottom of actual dates. As far as the engine goes it could have been put in at a later date when the original C10 engine became US or owner wanted to upgrade to the ohv engine.

XC10T puts it at around later 1946 to 47 as the T was for a Telescopic frame when they still produced the girder fork models. Your bike would have been a 3 speed at that time as the 4 speed box came in around 1951 on a ZC10S4.xxxx frame prefix.
The petrol tank you have is from a later C10L/C11G machine but should fit your bike.

Good morning Gents.

It seems that the Cut out and regulator unit for my project has been misplaced. please advise. Can i retro fir a Solid state regulator/rectifier? i have some old Japanese bits. An old Honda cd200 regulator rectifier. 6volt, will this work?

As your bike is dynamo and not alternator, it does not need rectifier only regulator.
By far the best solid state regulator to fit in the stripped out mechanical regulator box, in most peoples opinion is the DVR2.
Here is one from USA, but I'm sure you can source one closer..and cheaper :-\

Yes, fit a DVR2
I made the mistake of fitting a Wassel one because the local guy had run out
A $ 400 dynamo rebuild was the end result
And yes I did rewire the dynamo properly according to the instruction.
The regulator blew the LED Headlamp , another $ 90 and wrecked the Cyclon battery
Prior to that it had worked fautlessly using the MCR 1 regulator ( too small for the dynamo ) for 22 years since I have the dynamo overhauled.
And the 22 years is  well over 200,000 miles as I used to ride almost every day and regularly rode to events up to 1000 miles away.

Good day all.
Thanx for the advise on the electronic bits. I would have to arrange for the bits to be either imported, or sourced locally. the problem I have with the local guy, he wants to sell me a very expensive parts manual so that I can provide him with part numbers before he even starts looking for bits.
Any advise on a downloadable parts manual?

I have also attached a pic of the spray-work to date. Any comments constructive or otherwise are welcomed.
