British Bikes / Re: breather pipe
« on: April 14, 2018, 07:25:11 PM »
I canít comment on exhausts but why not use a small filter on the breather and terminate it under the battery somewhere. There are plenty of filters to choose from on EBay. I wouldnít pipe it into the exhaust, though if you wanted you could possibly run it into the air filter somehow.

The Classic Biker Bar / Re: Inner tube valve lock nuts

Iíve got a reply from Michelin.

Thanks for choosing Michelin inner tubes for your bike.
 
The inner tube is installed  with the conical washer sitting between the inner tube and wheel rim.  On a road bike the first lock nut should then be run down to lightly touch the rim, and then backed off by half a turn.   The second lock nut is run down until it meets the first one, then the two nuts should be locked together by using spanners to rotate them in opposite directions.
 
I hope that this helps,

So there you go my intuition came up trumps for once. I fully expected to have to take the tyre off and start again.

I checked the fit of the tube and valve with the washer and nut and just the washer before fitting the tyre. The tube looked the most comfortable when fitted with just the washer.

I donít see the point of clamping the tube to the rim with the nuts. If your relying on them to stop movement of the tube then surely you should be fitting tyre clamps.

I have tubes fitted to my landrover the valve stems on these are rubber and apart from size they are identical to tubeless valves made of rubber with no thread. And no means of clamping the tube to the rim even though they are off road tyres and run at low pressure.

From what Iíve gleaned from the internet. Some use one of the nuts as a locknut against the valve dust cap. If you are in the one nut inside and one out, but not clamping the valve to the rim camp, then the outside nut has to go somewhere and I suppose backing it up to the dust cap is as good a place as any.

Any how Iíve emailed Michelin to see what they say. We might as well get it from the horses mouth.

The Classic Biker Bar / Inner tube valve lock nuts
« on: March 23, 2018, 08:59:08 AM »
Iíve just got round to fitting the tyres and tubes to my Bonnie wheels.

The tubes (Michelin) come with two nuts and a dished washer on the valve stem. To me it seemed obvious that the washer is fitted on the valve stem between the tube and the rim, with the nuts fitted on the outside of the rim to stop the stem pushing back into the rim.

The tube I took off which was fitted way back when I walked briskly and could run up stairs had one lock nut tightened down onto the the washer on the inside of the rim. This was probably fitted professionally.

Having got the front wheel sorted I wondered why two nuts were supplied. So I did an inter web search. The inter web being what it is offered more permutations than Vernons.

The conclusion I have come to is that I have fitted the tube as the manufacturers intended, with only the washer (fitted dished side towards the tube) on the inside. And the two nuts on the outside not tightened down to the rim but locked together mid way up the valve stem, which will allow the stem and tube to flex on the rim without damage, and also to indicate any tyre or tube creep by an angled stem.

So if you still there and havenít nodded off after all that waffle whatís anyone elseís opinion.

Trouble is..... acetone will attack plastic

Good point, I didn't think about that.

Any how it still makes a good release fluid and if you're lucky enough to have a Land Rover Defender the used ATF from gearbox oil changes is free as is thinners from cleaning your spray gun if you do any paint spraying. Dunno if turps would work as well but it could be worth a try and it shouldn't melt your plastic bits.

Here's another photo. It does look like it's hand change. I doubt they would have been able to afford a Norton, assuming they would be more expensive than a BSA. Incidentally they were obviously in the Lake District they had travelled from Hull. I'm not sure I'd fancy doing that on a modern 'small' bike with all the refinements we have now.

Thanks for all the replies.
Heres a couple more pics from the same album taken at the same time.

It was my mum that always said it was a BSA, but she's not around to ask anymore. I did have my doubts but never broadened my search from BSA. I have another photo at home (we're away with family for the weekend) it's taken from the front and may give a bit more information.

Can anyone put a model name to this, it was taken in 1952.

Sorry pics a bit rubbish but I'm away at the moment and the posted photo is a photo of a photo in an album my sister has brought with her. That does make sense... I think.

A good home made release fluid is 50% ATF and 50% acetone or paint thinners. Gentle heat i.e. Immersing in Boiling water, and then freezing the part and repeating this process can work as well and shouldn't harm any plastic parts. All you need to do is to get the two parts to expand and contract at different rates to brake the bond between them. Gentle and persistent is better than in a hurry with a hammer.

Thanks Murdo I think that's what I'll be going for. Just got to decide whether to get them cheap on line or more expensive and have them supplied and fitted.

I've got a Dunlop ally WM3 rim fitted which measures 2.17 wide at the bottom of the flanges and only just gets insideAvons tolerances. Tyre width should be ok, in the past I had to deflate it to get the wheel out.

Thanks for the link L.A.B I must have been looking in the wrong place. Probably had cheese on my mind.

I notice your '?' Is that what you've got fitted. I've google them looking for feedback but not found much.

Tyres, oil, Indian Red....it's like asking what cheese is best!

That's a ridiculous comparison....Cheddar, preferably extra strong, is without question the best cheese.
Dolcelatte Pah.

I did use to run a K70 on the back with a Road Runner on the front, or vice versa, I traded my memory for grey hair. I reckoned this gave the best handling. But with the way tyre compounds have improved since then I was wondering what the modern day equivalent is. I'm fully expecting someone to say Maxxis are a good buy, to my mind they were the equivalent of the Kamikazi Skid Masters of the 70's.
