Twins / Re: A10 S/A forks
« on: 14 September, 2020, 21:10:48 »
once i had a wheel spindle bottom out at the thread leaving some play on the wheel on the clamp fork side. i had to cut a bit of hollow pipe to lengthen the step in the spindle so it clamped the wheel.

the flex at the wheel and fork bottom is usually taken up by the mudguard arched bracket acting as a brace. or your wheel and fork clamping is wrong.

Singles / b31 crankshaft bearings
« on: 14 September, 2020, 20:32:41 »
 the original b31 crankshaft bearings are now superseeded by SKF , NGK,  and others. but i m unsure as to whether i need c3 or cn tolerances with any of the three bearings. i ve also seen MRJA bearings the same sizes [ 1 1/8 and 7/8 ] but which suffix is correct? any recommendations?

Singles / Re: Retention of existing registration

hi rob,
 steve foden in the bsa o.c. will deal with you application and recommend to dvla that you should retain your existing registration. the original forms needed came from dvla but because of covid 19 i was able to download the forms instead. providing the frame number  matches the green log book everything should be smooth. my successful application took around 2 months earlier this year with dvla and that is with covid 19 issues at swansea.

hi john fd, towing a trailer sounds safer than what the uniformed casual spectator might think [ ahem ]. so perhaps you can post a photo of the hitching arrangement ?.

The Star and Garter / Re: BSA annual production figures
« on: 27 August, 2020, 21:20:22 »
slightly off topic, but i have met and spoken to another motorcyclist who did his apprenticeship at bsa small heath. whether there are plenty of other ex-bsa workers out there i dont know. but he did clear up a few queries i had. 2 production lines each for singles and twins and the willingness to adapt for special orders which i do not think happened with honda etc.. i wonder if anyone knows the meaning of batch number letters on a10 crankcase for example. one engine i have is wf stamped on the left side by  the breather outlet? war department maybe?

this is an interesting blog. i have a road rocket that goes light at the front end when i put  all my camping gear in the topbox and panniers. i have longer shocks and tried swopping about front fork springs to no avail. solo handling is perfect so the idea of a well made trailer seems ideal.
what prevents jack knife if you have to brake hard on a bend?

Twins / Re: Calling Pre OIF A65 Owners - Taming the vibes?
« on: 11 August, 2020, 21:33:40 »
 i am under the impression vibration is caused by rocking of the piston and weight above the gudgeon pin makes vibration worse. a solution is to use longer conrods and modern pistons with the gudgeon pin as high as possible. at least one norton race shop does this conversion using corrillo rods and special gudgeon pins.

hi editor, i had a spitfire with the vibration you describe. but if you go beyond 70 mph the vibration becomes noticebly less? however i felt the vibs moved from the pilot to the pillion seat and my future wife gave me a punch if i went above 65mph. have you tried cruising at 75mph?

The Star and Garter / dvla castle walls breached
« on: 21 July, 2020, 21:07:38 »
yes you ve guessed it , the dvla ...corona,covid, no emails, blah.blah.blah  have given my 58 bsa a10 its original registration number.
with help and recognition from the club. thanks steve foden and the lady from the dvla casework department.
i rebuilt it so running for detailed inspection but  not necessary as dvla has recognised the green logbook details.
new v5 logbook is in the post.

Twins / Re: BSA A10 keeps running rich
« on: 21 July, 2020, 20:36:08 »
pilot jet 25 may be too large if the silencers are restrictive types. i have a 2 into one with restrictive silencer and  i had similar problems mid range until i fitted a 15 pilot

Singles / Re: B31 oil leaks
« on: 01 July, 2020, 22:46:39 »
if you can keep the primary drive oil leak proof you could use that as a catch tank from the breather and in a top corner run a breather pipe to the rear mudguard. it was the method race teams used. however the engine oil seal will have to seal against the chaincase as with triumph units.

 hi mark, i ve been using a 12volt dynamo armature and stator without faults for a couple of years now. dynamo must be earthed properly but otherwise fit and forget. like many others i tried elect ign on an a10 but the maggie is more in character. mr wolfs k2f armature and remagnatism sorted out my magneto.
