Welcome aboard Fatmen4! (aka Mark.)

Hi Mark, and a warm welcome to the forum.

Congratulations on your Silverstone, sounds great! Funnily enough I was speaking to our club chairman Rob earlier on today, and he used to race his Silverstone back in the day. He asked me to mention to you that there is a database of surviving racers on the GRA website (http://www.greeves-riders.org.uk/racers_database) and to ask if your bike has a frame number (some didn't apparently), and if so what is it?

As far as help with your bike goes, there is a wealth of knowledge and experience to draw on within the GRA, and Rob said he would be happy to chip in as well, so the best advice I can give you is to join the club. There are details on membership at the top of this page, and I would certainly recommend it from what you mentioned in your post. Also, it would give you full access to the members only sections of the forum and you will also be able to post pics etc.

As far as problems with your fibreglass tank goes, as you can see from the posts on this topic it is not straightforward, with differing views and experiences. The best thing I can suggest is have a good read through all the posts and see if you can find a way forward if you are experiencing problems. It seems that not everyone has though, but if so there are some good suggestions there to try. If it's ok at the moment, it might be as simple as using the 'right' fuel and draining it out between rides. If it comes to it replacement tanks (as original) are available by the sound of it, and modern resins might be better able to deal with modern fuels etc.

Hope this helps Mark, to be going on with.

Brian.

Thanks for the welcome,

I have already joined , so will have to register properly so has to post some pictures.
The bike is looking really well to me , but to a trained eye it might look different , I'll welcome comment and advise once the pictures are on .

The bike does have a frame number , which i will add to the list when i've got to grips with the forum / site .

Cheers Fatmen4

Hello Mark.

Hello Mark. I can't help applauding your bravery if this really is the only motorcycle experience since an RD50!
Good luck with it.....

**Fatmen4** · 13/09/2010, 06:08 PM

Well here we are .
Just got engine back , fully re furbed , so here goes .
Now after a few more tips.And don't forget , any tips must be aimed at a Greeves / bike Dummy . So if you can keep things simple

whats best to use ,

gear box oil / amount
engine oil / amount
and best petrol mix .

I've also heard a rumour that there is a solution which will line my fibreglass tank ?? , stop it going to putty .

I would also appreciate anyone living in the north east who would be interested in checking the bike over when i finished it ,don't want to blow it !

cheers Mark

As another ex-Silverstone-racer I'll be interested to hear how you get on and will try to advise (if I know the answer

)

Which gearbox have you got? Many have been changed to four-speeders from the original five-speeder and their capacities vary.

Engine oil - presumably you mean what oil to mix with the fuel. I used fully synthetic competition premix at 30:1.

Originally the engine would have used "R", but it really is more trouble than it's worth, believe me...

**Fatmen4** · 14/09/2010, 06:31 PM

It's a five speed , does this make any difference ?

Only that the capacity may vary from the three different four-speeders it might have had fitted.

If the bike is 1966 and its frame number is 24RDS*** then it will be the original cambarrel Albion five-speeder - an excellent gearbox and very hard to come by. I'll check the oil capacity and come back.

**Fatmen4** · 14/09/2010, 09:13 PM

yes it is
24 RDS 157
and engine block no SP1 27 / 66 cc 892

Do you think this could be the original set up .

I did rescue it from an old timber shed . The owner said he'd raced it a couple of times .

Just sat the engine in tonight , now need to sort a full set of cables .
Had a new amal carb fitted , so that's the easy one i think, just needed to figure the length i needed .

Any advice and info welcome .

This doesn't have a front mud guard ? does it need it ?

Rebuild

If you get stuck with the rebuild and need a GRA member very close to you feel free to PM me and I'll help out.

**Colin Sparrow** · 15/09/2010, 09:19 AM

Gearbox oil: straight SAE30 engine oil.
Capacity: about three-quarters of a pint (can't find exact amount) but in any case there is a level plug at the back of the gearbox. Take out the plug and fill it until it trickles out of the level hole.

Chaincase: 100cc of TQF (automatic transmission fluid)

Do you know what clutch it has? Post a photo if you're unsure.

The bike would originally have had a front mudguard. You don't need it for racing; it's just more weight.

If you post a couple of pictures one each side with the fairing off, say we'll sort out exactly what you've got there.

A griffon clutch , i believe .

I'll sort a few pictures and pop them on .

Thanks for the help so far
