Singles / A10 shoes in M20 drum?
« on: 10 October, 2017, 21:35:20 »
I have no brake shoes for my WM20 and they are very hard to firnd. I have a spare set of 7" A10 shoes that fit but the ends of the shoes are somewhat narroer than the cam and fulcrum pin. Would this cause problems?

Bantam / Plug issue?
« on: 28 July, 2017, 17:32:27 »
I treated my D1/D14 to a new spark plug and this fixed her performance problem but the other night on the way to a Club meeting she started intermittently missing. The problem disappeared after a couple of miles. I had exactly the same symptoms on the trip home.
I was wondering if a hotter plug might be indicated? Current plug is an NGK B7ES.
Perhaps she developed a need for a bit of choke until warmed up. Although has not previously.

The Star and Garter / Just got back.....

...from a very enjoyable South Derbyshire Camp.  Nice campsite in the grounds of a very pleasant and welcoming pub with good food.
A lovely rideout on Saturday through some wonderful Derbyshire Dales countryside a pretty some villages. Good company and met old and made new friends. What more could you ask for.
Huge thanks to Mark and Giles for all the effort in making this such a succesful weekend. Giles preparation work in planning the ride-out route deserves special mention.

Congrats to Norfolk Branch for a wonderful camp weekend.
Lovely site, great rideout via ferry and glorious Norfolk countryside to a very interesting transport museum.
Great BBQ and some interesting prizes among the many won by the rafflers. They even arranged some glorious weather
Well done to Rob and helpers for making this such a success.
Thank you!

Bantam / Er, er she's started hesitating.
« on: 03 June, 2017, 17:27:28 »
My Bantam (D14 engine) has recentky developed a hesitation at wider throttle openings. I suspected I'd messed the petroil mix but I've drained the tanks and replenished with fresh 25:1 fuel. Draining via the tap meant I could check fuel flow and its fine. Have stripped and cleaned the carb, which was clean when I looked inside. So, the hesitation is not likely to be fuel/carb related.
I have made no changes prior to the developement of the hesitation issue cropping up.
I'll check the plug and points tomorrow but in the meantime has anyone any ideas?

... from a really enjoyable Open Day weekend. I met up with old friends met some new and can now put faces to some 'virtual' mates from here.
Its been some year since I've done an Open Day (Field Day) so my first at this venue but I think it works well with a nice camping and great facilities.
Lizzy is thrilled with her rosette and it's going in her treasures cabinet.
A big thanks to all those who put in the graft in advance and during the weekend to make this so successful.

kindest
Dean

PS I never did find the float needle but that will teach me to impulsively decide to strip the carb in a grass feild!

Pre War / Wayward headrace
« on: 14 May, 2017, 20:01:21 »
I have been running in the Sloper and when done was planning to fit the sidecar so my wife could join me at this year's International.
Well, its turned into one step forward and two back. Firstly the end stop on the straight pull twistgrip went awol. Eventually I'll have to get one made as they appear unobtainable but i've sorted a bodge for now.
But the second problem is the killer. The upper steering race decided to work its way out of the headstock and nowt I can do will get it to stay in. A previous owner had obviously had similar problems if the dimples in the race are anything to go by. It looks like he'd ready applied some force to the steering top nut!
Just make life more challenging I have not been able to find  replacement bearings. Nor am I sue they will not also work loose.
Any ideas or suggestions welcome.

Singles / WM20 paint
« on: 05 May, 2017, 08:51:32 »
I am thinking of painting the WM20 myself with out the aid of spray kit. I once painted a complete Beagle by hand in the spare bedroom and nobody ever guessed it was a brush job, so i know what I'm letting myself in for.

So, does anybody know a source for approapriate paints to get an authentic colour finish for WW2 British military green than can be applied by brush and aerosol?

Singles / How many rings in an M20 piston
« on: 25 April, 2017, 09:35:39 »
I've got a piston but needed rings. I can only find the usual three ring sets yet the piston I have has 4 ring grooves. The top (extra) one is thinner than the other, non oil ring. Having just got a NOS BSA replacement piston this also has 4 grooves but came with rings fiited, but only three. the top groove has no ring. Perhaps the top groove is not a ring groove but serves some other purpose. I've not come across this before so can anybody explain what's going on?

Sidecars / A bit in the side
« on: 13 April, 2017, 19:48:34 »
I can't recall why but some time ago I decided I would fit a sidecar to the Sloper. So I found a period chassis and braked wheel locally and sorted out the fittings. Boxing day 2015 I got bored so started building a body. I had alreday decided on a replica BSA Model 7 as I only needed a single seater.

Only then did I think about gearing down the engine to cope with the extra load. I was a bit of a twit really not to make sure I could sort this before all the effort to on the chair. The Sloper owners' handbook is very helpful in explaning how to set up a sidecar and the engine gearing options. But could I find an engine sprocket for a 29 Sloper...not  a chance. I even visited a local gear manufacturer who offered to have a go at making one. 150 if it worked, no charge of it didn't, whcih is decent of him but an expensive way of getting a sprocket especially as I would be guessing at the size to go for.

Then as it happens I obtained an M20 engine sprocket this week (it came with the bits of an almost entire bike) so I thought I'd might as well try my luck and see how close a fit is was on the Sloper. Its fits!!!!! So, I have an 18 tooth sprocket on order as I type (19 plus postage). Oh happy man ;D

Only trouble is that when I fit the sidecar I have no space left to store it, which is probaly why its taken me nearly three years to get the job done >:(
Another begging letter in the local newsletter asking for storage space will be appearing soon.

Twins / Gearbox squeal!
« on: 07 April, 2017, 09:05:38 »
I  took the Super Rocket out yesterday for its MOT. As I pulled away there was a loud squeal from the gearbox (in gear and clutch engaged, ie driving). I recall it did similar last time I had her out in November. She tends to stand around most of the year waiting to be used. The squeal goes after a few seconds but might re-appear once or twice in the first few hundred yards and then clear

I am thinking bush spinning? Time to get the gearbox out and stripped.

Any thoughts?

(this will teach me to call her the bike that's all sorted and just for using!)

Twins / Adjusting a TLS brake
« on: 19 March, 2017, 11:45:06 »
I am now ready to assemble the TLS on my A10. The machining and welding is done so lets hope it all lines up!

For now though I need to know how to adjust the brake arms to be sure its operating as a TLS and get optimal performance.
Intuitively I am assuming that with the rod that links both brake arms disconnected I operate both brake arms fully manually untill then and with my third and fourth hands adjust the linking rod.

Does anyone know of a better approach or the BSA recommended method?

The Star and Garter / Handy hint
« on: 20 February, 2017, 18:06:38 »
Never asume you will remember how parts went together months down the line when it comes to reassembly.
Photos are really helpful but video can be even better especially as you can make verbal notes.

PS does anyone know which way round the steel brake shoe plates should inserted in a TLS brake plate  :-[ :-[
