I have a TRIBSA with a 500 unit twin engine in a B25 frame. The engine does fit, but the rear part of the LH frame loop has to be modified with a hammer. Because it is all so tight in that area, It is imposible to adjust the primary chain tension without taking the engine out of the frame. Not great!
The side stand needs to be very long, the bracket modified or made cunningly cranked.
i used a Triumph high level siamese pipe from Armours (unchromed) and had to have a new RH exhaust tube made up for it as the std version wants to pass through the frame downtube!
The oil in the frame set up gives you more room to package an air filter/battery/assorted electrics in the space behind the engine. You can also buy competition side panels from Rickman which cover up all this junk.
Overall it is a really nice bike for road and trail.
I would add a picture if I knew how to do it!
I am looking for a folding gear lever for my bile - anyone know a supplier?
Trying to re-furbish a set of Ceriani type forks, probably from a Greeves Griffon.Does anyone know the correct spring length and width? Can new ones be bought anywhere? What weight and quantity of fork oil should be used?
It seems likely that the bike's registration number was 127 KUF, but as yet, I can find no information about the owners. Anyone have any ideas? Does anyone have any pictures of this TR5 Trophy in the early fifties?
I am lucky enough to own a (fairly) original 1950 TR5 in 'oily rag' but useable condition. I would love to find its original registration number so that I can research its history fully.
I am informed by the VMCC that it was shipped from the factory in early March 1950 to Redhill motors in Brighton. If it was registered in the East Sussex area before Nov 1950 then it would almost certainly have a
KUF registration. Given the realtive scarcity of these bikes in the UK, there will not be too many with the KUF registration, so it should narrow the field down. I would be eternally grateful to anybody who has any information about a rigid 1950 TR5 Trophy with a KUF reg.
I can't remember who won the 87 championship or on what - Edmunson on the Honda? - but I don't think it was a Yamaha and I don't think Yamaha had any official entries on YZs in enduros. Does anyone know if this bike is genuine or not? It seems a fairly strong claim to make if it isn't true. It's a pity as the bike looks very nice and should sell well on its own merits.
I have acquired a 1986 XT250, which seems sound in wind and limb. It feels nice and sharp in the low gears, starts well hot or cold, but will not pull above 5000 rpm in top which seems to be around 55mph (its a KPH speedo!).
My current theory - it's much cheaper than rebuilding the engone - is that it is overgeared. Does anyone know what standard gearing is? Has anyone tried different gearing? Is it a nice bike or should I have bought a Honda XR or XLS - be gentle wit me!
Found Steve and Marlimar-UK (email - steve@marlimar-uk.wanadoo.co.uk). he was very helpful, sent the bits I needed immediately. Problem solved, bike runs perfectly!!! Wish everything was so simple. Particularly finding the correct rear light for my Bultaco Alpina, which is proving very elusive.
Just acquired what I am led to believe is an Ossa TR77 - a 250cc Ossa of 1978 vintage (Frame No 8-700191). Does anyone know anything about these bikes? and more importantly does anyone have the correct air filter and side panels for this bike? It might also be very useful if someone can remind me how to attach a picture - I can't remember how I did it previously and the help menu doesnt seem to have anything useful to say
Hi Greeves - thanks for your information. Bultaco UK confirm that the engine No and frame No suggest it was made in November 1971 - This is great news in the Uk because it means no road tax is payable (saving
Wow what fantastic service - chatted to Dave Renham of Bultaco UK (Inmotion) yesterday lunchtime - all the bits I wanted are here today and at a sensible price too. The service also includes a certificate of dating, so that I can register the thing
I finally found a Dunlop 19" at www.vintagetyres.com
Tel: 01590 612261. It will get me through an MOT and preserve the bikes originality. I have also acquired an 18" Akront rim through the somewhat eccentric route of buying a knackered Montesa Cota 200 - Anyone interested in some Montesa bits? - I have most things now except the rims!! I've got to get rid of it quickly before the wife finds out.
Thanks for the excellent response. The general concensus is to make an 18" wheel. I have found a genuine Frannie barnett hub which is 36 spoke. Any recommendations for a rim and a wheelbuilder?
It still leaves me the problem of finding any sort of 19" trials tyre for the original wheel - Ill keep on looking
Hi - I'm new to the forum and new to the pre '65 movement. Saw the demo at the Historic motor sport show and it re-awakened old urges. I've acquired an unmolested '59 Francis barnett Trials 83, which needs new tyres. I can't find a 19" trials tyre anywhere. Millers advised me to build a new wheel with an 18" rim. Is this the only way?
