Which BSA do you ride? / Re: A7 Star Twin
« on: 11 August, 2017, 19:35:21 »
Where BSAs Dare has been my bedtime reading this week too - it's made me want one!  :D

Great to see those bikes clocking up some real miles STAR TWIN. Keep flying that flag  ;)

Singles / Re: BSA B33 sticky exhaust valve advise please
« on: 11 August, 2017, 19:30:48 »
Hello, Richard.
How's the flow of oil to the rockers?. I know that the B31/33 doesn't have a feed directly into the valve guides, at least my B31 doesnt, but relies on what splashes around after its been through the rockers. Try slackening the feed pipe banjo bolts when the engine is ticking over to see if some seeps out. Putting your finger over the oil return in the tank will force more oil up to the rocker feed so you can check it isn't blocked.
You could also check that the banjo bolts have been put in the right order as they do have different sized holes. Smallest for the inlet, next size for the exhaust and the biggest for the drain pipe at the back.
My Matchless single inlet valve has a separate feed that can be metered by a pilot type screw on the head. Helpfully, the book says if you hear the valve squeaking then increase the flow of oil  :-\ Did you hear any sort of chirruping noise before the valve stuck?
As Julian says, it could just be a build up of carbon, so a head off job might be the only sure way to find out. It's not a difficult job and can be done in an afternoon.

I do wish they'd leave these old marques alone instead of trying to trade on their history. It's bad enough seeing the 125cc Chinese Landfill bikes with once respected names on their tanks buzzing around  :-\
A mate of mine has just called round with his brand new Norton - it's trying to look the part if you like that sort of thing - but talk about mechanical noise  :o If any of my old bikes sounded like that I'd be stripping them down straight away to see what had failed. He even admitted to being embarrassed by it after he'd heard the 65 year old A10. I got the distinct feeling that he won't be keeping it long.

Twins / Re: A10 Dynamo belt-drive conversion and Rodark panniers
« on: 08 August, 2017, 20:09:49 »
Well, the belt is on and quite frankly, I'm amazed at the difference. The engine is almost eerie in it's mechanical silence. The dynamo chain was pretty well knackered and very slack, mind you. The old GF now makes my modern Bonnie sound like a tin can of nuts and bolts  :o Having said that, it is a Triumph so what do you expect?  ;)

Steve (wot's now had continuous rain since about 2am and still no sign of a let-up. Summer? My arris!)

Thanks, Doink.
The belt conversion arrived this morning actually. Tomorrow's forecast is typically summery with rain all day so it might get fitted if there aint too many chores to do  ::)
The concentric was on when i got the bike. It looks like a new carb. Without stripping it I dont know the jet sizes. It does run very cleanly but im not keen on the appearance. When i can justify another 300 quid i was going to order a new original type amal, though a monobloc is only around 170.  I fitted a new monobloc from amal to my 53 Matchless G9 and it was set up perfectly straight out of the box.
There isnt a lot of room above the carb top with the concentric but having spoken to a very helpful chap at amal (excellent folk to deal with) it seems that the concentric is no taller than either of the others.
Im sure if you rang them theyd be happy to help out.

Twins / Re: Scruffy Conical Hubs
« on: 06 August, 2017, 21:30:06 »
Vapour blasting gives a nice finish. Done with glass beads/water it closes up the pores in the surface and polishes it which reduces its ability to collect the muck so cleaning is easy. Powder coating looks ok when first done but if the preparation isnt top notch corrosion can soon get underneath and make it flake/crack. Once that happens it all gets to look scruffy again rather quickly. Same goes for clear lacquer on an ali surface. Wouldnt do for it to look like a jap crankcase would it?  ;)
If you do want em in black then I would go with a single fairly thin coating such as engine paint which lasts very well and would be easier to touch up.

Which BSA do you ride? / Re: Recently restored B31

A fine looking machine. Well done and good luck with the 'hoops'  :D
Its good to know that Britain's finest are still being restored around the world.

Singles / Re: First classic
« on: 03 August, 2017, 22:00:00 »
They are pretty easy to work on, Phil, as most things are easily accessible. Balancing the carbs (done on the cables) is an acquired knack, best done by ear rather than fancy gauges, but once set up tends to be reliable. Exhaust nuts need a proper spanner to loosen and it needs doing as soon as you get the bike to make sure they havent siezed on the threads - an expensive repair! Threads can be treated with optimol anti-seize compound for peace of mind. Valve gear can get noisy but is usually due to endfloat on the rockers which can be taken up by slackening the head bolts and moving them in slightly.
There were reports of valve failure around 60,000 miles at one time, though Ive no personal experience of that.
When I ran Beemers the 'go to' spares supplier was Motobins and I dont recall ever being let down, though in fairness, the bikes were largely trouble free, a starter motor being the biggest expense on one of the R100s.
On a more prosaic note, those cylinders sticking out as they do, can get in the way when the bikes in the garage - shin pads help  ;)
 Hope the BSA crew will forgive this little foray into German engineering.

You've certainly got some pondering to do, Phil. Whatever you decide, for a first classic I'd tend to go for something for which spares are plentiful and reasonably priced. Triumph, BSA and AMC appear to be well up in the vanguard in that respect, perhaps followed by Ariel, though with Triumph, you're probably going to be limited to twins. Nothing wrong with a twin of course, though there are twice as many big moving bits to repair should the unthinkable happen. A single keeps things simple and all are very easy to work on (and they also sound the best  ;)  ), most designs being based on 1920s or 30s technology.
The BMWs you mentioned are fine machines if you can find a good one. My first Beemer was a R75/7. A beautifully smooth engine, much better than the R100RT and R100RS that I had later. They always felt a bit rough/lumpy in comparison and I found the R100RS to be decidedly uncomfortable at anything below 70-80mph. I understand that the 600cc boxer was the sweetest of the lot. Naturally, spares are expensive and the bikes do have their mechanical foibles but if the bike is well sorted then you shouldn't need many  ::)

Good luck with your deliberations.

Twins / Re: Fitting of M20/21 girder forks to a late A10 frame
« on: 03 August, 2017, 18:59:47 »
I can see why someone would want to fit girders - that bike looks so right, Trev. Only thing is you've set me of wondering about my B31 now  ::)
Perhaps a hand gear change linkage too  ;)

Steve

PS I enjoyed looking through your website. I shall be paying another visit or two. You passed very close to me when you ventured North over the Humber Bridge. I presume you got through the Yorkshire border control point without too much difficulty  :)

Hello, Phil.
I know it's a bit heretical on this forum, but being of a similar, albeit not quite, stature, have you looked at the AJS/Matchless 500 singles of around 1960? I have a 1961 G80 which has a similar bulk/seat height to my modern Bonnie. It also has enough grunt not to be phased by hills when a larger pilot is aboard  ;) The physical size difference when standing alongside my Golden Flash or B31 is quite pronounced.
Sorry for mentioning the 'opposition', folks, but we love all, well most, old bikes don't we?  :)

Thanks, Dean.
The panniers are now resplendent in gold, well, Valspar E1610 - quaintly named metallic beige by the supplier. Im rather pleased with them. Ill give em a few days to harden before refitting them but I will post a pic of the progress.

As for the dynamo drive belt conversion. Thanks for the recommendations, chaps. It has been ordered today - along with a pair of front numberplates. A bike just don't look finished without em  ;)

Singles / Re: B31 help
« on: 01 August, 2017, 22:53:59 »
Hello, Dedge.
I have a 1953 B31 (plunger sprung 52/53 spec jobbie) and your head and barrel look familiar to me. For what it's worth, I believe that there should be a gap, albeit a very small one between the flat surfaces you describe and that the seal proper is made by the circular machined surfaces. That small gap ensures that the circular surfaces will mate together tightly. I know the service sheets indicate that it's a dry joint but I do use a light smear of that truly marvellous jointing compound, Wellseal  :D
