Hi Rory,
The proper tool consists of a threaded plug that goes in the top of the fork stanchion which has some smaller dia allthread in the centre. This pokes up through the top yoke and a nut and large penny washer pulls the stanchion up against the spring until safely in the top yoke and the clamp bolt in the bottom yoke is tightened to keep it there.
Its easy to make if you have an old top nut and access to a lathe, by turning down the hexagon to slightly lesser dia than the thread and drilling and tapping a hole for the allthread in the top. If you want to make one from scratch, remember the top nut has a 28 TPI cycle thread.
Some people (me included) have got away with a large enough broom handle screwed in by hand and pulled through whilst the third hand tightens the clamp bolt, getting it close enough for the top nut to catch which will then finish the job. Depends how strong the springs are.
They are great bikes so worth getting your hands dirty! Best of luck with it!

Hi Rory,
The 1970 forks were fitted with shuttle valves to provide 2 way damping. As you said you drained out an oil and water mix, its possible that the shuttle valves are gunged up with something nasty. This would cause the locking if the oil isn't squirting through in the right direct when needed. Sorry but the only way to be sure is to strip them down and give them a good clean. When done, 15w or 20w oil will be more than adequate. 5W is a bit thin in my opinion.
You'll need some readily available special tools, one to undo the fork seal holders and the other to draw the stanchions up to the top yoke on reassembly.
I would recommend you do this as its clearly a safety issue with the way they are at present.

Try Tony Cooper (TC Motorcycles) of Halesowen, he comes highly recommended by lots of folk. His phone no is 0121 559 2405. He is a great guy, very friendly and helpful.
Tell him I pointed you in his direction

Hi Kez
Can I use the picture for the front cover of a future edition of The Star?

The cut off for zero licence fee (free tax) is a rolling 30 yrs so bikes built before 1st January 1977 are included. Remember it is the built date not the registered date.

Steve has been away on Hols but is back now. I know his backlog was 4 weeks before he went, so it may be longer now.

« on: 27 May, 2017, 15:12:54 »
Worth a try, but it may be more trouble than its worth as the 3/32" 'step' between the bore of the carb and the inlet on the head may upset the mixture.  This happened to me donkeys years ago when I pulled a stud out of my Triumph 5TA manifold (7/8"bore) and my local breaker had an 1.1/16" manifold in stock. OK, the 'step' was the other way round but I just couldn't get it to run.
If you want to try a new concentric, then a 622 is what you need.

Hugh, whereabouts on the throttle are you when this happens? If its up to half way and you open it up further and this persists it could be your main jets are too small. Try fitting a pair of next size up, or maybe get the size after that aswell while your at it and see if it makes a difference. They're cheap enough.
Caerphilly mountain is a good testing ground by the way, as is the Bwlch up from Nant-yMoel.
Let us know how you get on.

Julian is spot on. I had a C15 and exactly the same thing happened, when I looked at the joint face on the cover, the distortion is obvious. I have had many Monoblocs over the years and had never come across that before. Hitchcock's do a replacement, if you're quick they might be able to despatch today.

Ctek chargers are really good and they keep the battery topped up nicely. Just use them as you would any charger. i.e + to + and -ve to -ve. If you get them the wrong way round, the charger will error and shut down so wont melt the battery.
Hope this helps

I just checked the DVLA system and they dont show a record of that number for a BSA. Its therefore likely that if the bike is still in existence the original number may have been sold as a cherished plate or a subsequent owner lost the log books etc. As such it will have an age related number which makes it difficult to identify. The only hope is that the present owner knows the original number and he gets your request.

Chris, if the local authority do still have the records, you will need to ask if they include the frame no. as the DVLA need this part of the evidence and a picture and rubbing of the actual frame no. otherwise they will not give you the original number.

Mike, by all means buy an inline check valve if you wish, Polly Palmer still sells them for around 40, but first I would re seat the ball valve that is behind the Oil Pump and fit a new ball 1/4" dia and spring part no. 68-353 and see how it goes. The spring does weaken as time goes on. I don't get any wet sumping on my A65 or A50 and this is after being laid up for three months or more. 
Re the where do the oil in the crankcases come from, well the timed breather mostly but also, anywhere else it can find a way, via the main bearings into the timing side cover and the chaincase as it blows past the seal. It all depends on how much is in there.
Hope this helps

Hello Ted
Are you reasonably close to Birmingham? If so, the Birmingham branch may like to be exhibit this on their stand at the NEC Classic Motorcycle show in September.
Also, I would like to do a feature in The Star on this bike. If you agree, please send me some more details and pics to
