Singles / M33 shock absorber
« on: 01 August, 2021, 11:44:02 »
In a similar fashion to my clutch problem, https://www.bsaownersclub.co.uk/bsaoc_forum/index.php?topic=12461.msg66633#msg66633 I've found that my shock absorber nut was loose. Just like the clutch, the problem is that the splines on the crankshaft do not protrude from the face of the cush drive bearing sleeve; the lockwasher has nothing to secure it.

If (similar to last time) the clutch bearing sleeve is the wrong one, replacements are very thin on the ground; it doesn't look like I'll be riding the bike any time soon unless I can come up with an alternative fix (The correct clutch sleeve is also thin on the ground). So, is using thread locking compound an acceptable substitute for the clutch and shock absorber locknuts? If so, any particular one? The engine and clutch sprockets are out of line by about 1/8th"; what's the maximum amount they should be out of line?

Singles / Bike moving off problem
« on: 11 July, 2021, 21:24:59 »
When I start my M33 moving I have two problems. One is that as I start to move off, the bike is hardly driving until the last bit of clutch lever movement, when it comes in all at once. The other problem seems linked; until the bike is travelling at more than about three miles an hour it moves forward in jumps, then once it's going it seems fine. It started doing both these thing recently with no previous symptoms, and seems to get worse the further I go on any given ride. Of course it isn't conducive to safe moving out at junctions, or doing 'U' turns on country roads.

Any ideas?

Singles / Fork oil to see on an M33
« on: 19 April, 2021, 18:08:00 »
I've just changed the fork oil on my M33. Once the new oil is in, should I be able to see the oil or should it be out of sight down the 'ole? I put 5 oz in each fork leg. I changed the oil for two reasons: the forks were a bit underdamped, and I couldn't see any oil when I took the top caps off and looked inside so I wasn't sure if the level was a bit low.

By the way, the 1:1 mixture of 40W engine oil and 15W fork oil I used is just right. Here's a photo of the fork legs in case they are not the standard items:

Singles / M33 noisy tappets, or...
« on: 04 April, 2021, 12:30:23 »
No matter how many times I try to adjust my tappets, there's a noisy tappet sound in the head. I've been advised to support the weight of the pushrod, via the inspection cover in the head when setting them, but it seemed to make no difference. Is there something I'm doing wrong, or could something else be the problem?

The Star and Garter / Vintage Screws
« on: 16 March, 2021, 11:01:16 »
I just ordered a couple of Whitworth bolts; I needed a 3/8" coach bolt to fix a launderette tumble dryer. The bolts arrived quickly and are nicely made with rolled threads and a nicely made square nut. I'm thinking the firm's products might be useful for owners of sidecars so here's the website:

They also do machine screws.

Singles / A crack in the cover
« on: 04 March, 2021, 12:52:16 »
I have a crack in the timing cover of my M33. It seems that the screw that retains the oil valve ball and spring has been over tightened, and the boss around it has cracked. When the engine is running, a little oil weeps out.

I've considered using JB Weld to make a repair, but I'm not convinced it will hold under the oil pressure. Perhaps getting it welded would be better, but I'm concerned that the case may then become warped. What should I do?

The Star and Garter / Insurance renewal; who to go for?
« on: 12 January, 2021, 17:47:32 »
After a distasteful experience last year with the claims handling "department" of Carole Nash, I'm looking to move to another company. The department is actually a separate company who tried very hard to get me to hire a bike, and wanted to pick my bike up and take it away. It's an old Japanese bike that been very reliable; but because it isn't worth very much it would have been written off and I doubt I would ever have seen it again.

So who to go for? I've seen some recommendations in old posts, but is this advice still good? The names that came up were Footman James, and (I think) Peter James.

If you have had to make a claim with any company, how were you treated?

The Star and Garter / Where are the handbooks?
« on: 08 December, 2020, 10:15:40 »
I went to look at the handbook for my M33, but it's not on the website. I'm sure I've seen it there before, so what is going on, please? Am I looking in the wrong place?

The Star and Garter / A 1955 road safety film
« on: 17 November, 2020, 17:57:16 »
This is a road safety film made by the Liverpool Motorcycle dealership Victor Horsmans in 1955. As a rider of a 1953 BSA, I found it full of good advice and very entertaining.

Singles / Wiring under the rear mudguard, how is it secured?
« on: 15 November, 2020, 22:41:43 »
How do I secure cables that run on the underside of the rear mudguard on my M33? There's a clip near where the cables dive through the mudguard to reach the back of the rear light, but that's it. The result of course is that the tyre has worn through one of the cables. There are no cable clips that I can see.

My mudguard has a broken hinge, and the mudguard is secured with a plate bolted to both halves. Is the rear of the mudguard supposed to be detachable when hinges up, or does it just hinge? I need to consider how to run the cables, to allow for getting the hinge fixed in the future.

Singles / M33 engine case screws
« on: 04 October, 2020, 16:58:59 »
I want to replace the primary drive cover and timing cover screws on my M33. I'm after Allen screws which is what I've already got, but some of the sockets in the heads have worn round, and the screws in the timing cover are too short. I've seen several places where a kit of these screws is for sale, but they refer to them as Whitworth screws. This doesn't seem right to me; surely at 26 tpi (I checked with a thread gauge) they should be cycle thread. So my questions are:
1)
Where can I get a set of screws that will fit?
2)
What nominal diameter are the screws in the timing case? I measured one of the screws that was in there, and it's between 7/32 and 1/4"; I want to buy a tap to clean the threads out, but I'm not sure of the size.

The Star and Garter / Anybody up for a ride out? North Bucks
« on: 17 July, 2020, 19:29:01 »
Anybody going out on Sunday rides near me? I'm in North Bucks, or more accurately the South part of Milton Keynes. I'm on an M33. There's also the lighter week day evenings, at least for a few more weeks.

Forum Problems / Old forum posts link
« on: 12 July, 2020, 21:25:30 »
Hi, the link to the old forum doesn't seem to work. The only thing on it that does anything is a link back to the main BSAOC site.

The Star and Garter / Road speed in the 1950s
« on: 06 July, 2020, 13:33:18 »
What was a typical speed for most traffic on good roads, in the 1950s? I'm trying to relate the performance of my M33 to general road speeds and cruising speeds, when it was built in 1953.
