British Bikes / Smiths speedo as fitted to 73 Bonnie.
« on: July 08, 2018, 07:40:26 PM »
Has anyone stripped a smiths speedometer where the trip knob and shaft come horizontally out of the body. I canít get the internals out of the body because of the shaft. I notice that TMS sell the shaft separately so Iím guessing the shaft should pull out of the body, mine however is refusing to budge with lightish pulling. I donít want to put too much strain on it in case this isnít the correct way to remove it.

British Bikes / Loctite 5990
« on: May 04, 2018, 01:38:29 AM »
Has anyone used Loctite 5990 for sealing Triumph push in exhausts, or had any experience of using it. Is there a better product? There are a few gas fire flue sealing silicone type products which may work. These days there must be something better than Gun Gum which is what I used 20 odd years ago, and only seemed to last a week or so before the exhaust was rattling around in the head causing backfires loud enough to wake the dead.

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.

Identify these bikes! / My dads Beeza

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.

British Bikes / Tyres for '72 oil in frame Bonnie.
« on: April 27, 2017, 08:58:46 AM »
In the next month or so I'll be getting round to fitting tyres to my T120V Bonnie. Can anyone advise, recommend or just say what tyres they have fitted or have experience of. The last tyres I bought were Battleaxes for my Suzuki Bandit a few years ago but doubt they would be suitable!

I'd sooner go for function over form but don't particularly want something that looks ultra modern. The bike won't do many miles so wear rate isn't a problem. It will mainly get used in dry weather but I'd like it to be controllable on wet roads. I believe I left my loonatic days behind when my hair went grey but I'd still like the tyres to be fairly sticky just in case.

Tyre sizes are,front 100X90-19. Rear 110X90-18. Both are on spoked rims so will need to be tubed type.

Thanks in advance for your replies.

British Bikes / T120 Fork slider dilemma.
« on: April 07, 2017, 02:53:34 PM »
I'm currently rebuilding my '72 T120v  Bonneville. I've just rebuilt the fork legs, the left hand slider has an oversize wheel spindle groove in the bottom, approximately 19mm diameter as opposed to 17mm which is what the spindle measures and the studs are on wider spacing. The right hand slider has the correct size groove.

Both sliders were replaced as a pair in the past though I can't remember quite when. I still have the original ones, the spindle grooves are the correct size on these. The three sliders with the correct groove have a letter 'J' stamped whereas the incorrect one doesn't have any markings.

I haven't a clue how I managed to fit the end cap all those years ago or why I didn't notice it then!

Does anyone have any idea what the offending slider may be off. I've rang a few suppliers to try and get another one but so far I haven't been able to get hold of one and no one seems to know why its got a bigger spindle groove in it. Apparently all concical hubs were the same and even the disc braked models had the same size spindle.

British Bikes / oil in frame tank mounting
« on: January 20, 2017, 02:14:21 PM »
Hi new member here but I've been dipping in and out for some time now.

I am rebuilding my '73 T120V, it's been languishing in the back of shed number two for over 20 years and has got into a bit of a state. I've owned it since '76.  Over the years I think I've replaced everything except the frame and seat base. The first thing to go west was the engine, it spat a gudgeon pin out of the crankcase on the way back from a Blue Oyster Cult gig in Leeds! I replaced it with a T140 Jubilee engine, you could pick that sort of stuff up quite easy in those days. The rest was just wear and tear and a couple of prangs.

In An accident at the IoM  TT  in '81 the tank mounting on top of the frame tube was ripped off. I came off worse than the bike, broke my back and spent a good while in Nobles hospital. Any how I made a new bracket welded it on and suffered the consequences of a rush job until now. So I've removed it and I'm in the process of remaking it. However I can't find any dimensions of the bolt or the position it's in on the frame. I've got two measurements in my notes from over 30 years ago. One of 8.5" and another at 9.5" back from the steering head. And I think the bolt is 3/8" UNF.

Could anyone clarify these points for me?

Thanks in advance.

Grunt.
