Cheapest way into trials is certainly not any classic class like twinshocks or pre65.
It used to be, but like many things these bikes are becoming fairly expensive as you have found.
In my opinion the cheapest way into trials is a more modern bike, mid to late 90's and beyond can be bought really cheaply. Spares availability and cost will vary of course.
Hi Bisby I will do what you suggest if nothing else helps, but I wanted to buy or borrow a socket that fits as Stecks suggested I now know its a 3/4 drive socket as 1/2 only go up to 32 mm.
There are plenty of 1/2" drive 36AF sockets available. Try ebay, I would use an impact type with a full hex.
The problem is, mainly of these bikes have had neglected maintainance in this area for decades and these parts can become "as one"
The Inner bushes were not plated from new, nor was the engine mount. Add to that the plating on OEM spindles was dire and you have a recipe for the parts to literally fuse together over the decades.
It's so much less painful to just cut the thing out and change the spindle.
This problem is not restricted to Bultaco's either. Yamahas are prone to it too.
hi all just got a rough 199 to rebuild and am having a nightmare getting the swingarm spindle out .wd40 and a big hammer have just mushroomed the end. am i missing something (brain) or is there a trick to get the bugger out?
Yes there is. By scrapping the spindle. They can corrode so badly to either the rear engine mount or one or both bearing sleeves that it's virtually impossible to salvage the spindle. I have only come accross one single bike where the spindle came out whole.
There are numerous methods to removing the swinging arm in this case. I prefer to drill both ends of the spindle to 1/2" diameter dead central so that the spindle ends can collapse and release the arm. It's then easier to work with just the swinging arm in a vice.
Others saw through the spindle, but whatever you do try not to cause any damage to the rear engine mount as it's width is crucial to the tolerancing of the complete system.
It appears to be a simple Schrader valve in the top cap and we tried this system many years ago. A company called Goki also had a tube that connected the top caps together to equalize pressure between the two forks. The problem lies in the fact that the air heats up in use and exerts greater pressure, however, the fork damping fluid also loses viscosity with temp rise. The decreased fluid viscosity coupled with the greater spring/air rate causes a loss of damping control in fork action.
It's actually a self contained air spring which is used with a shorter compression spring.
I know what you mean most Classic rules prohibit disc brakes too but it is as was available to be bought by me you or anybody else in the late 60's so is it right not to allow it in ?
Tis interesting! Out of interest what year approximately did the clamp on talon disc brake conversions appear? Mid 80's??
I have a Cub on the old coil system and need to add a kill button. I am not the best at electrics, can anyone tell me what and which terminal I should earth for the kill switch? There is no battery by the way.
Jim, Grounding the LT side of the coil should do it. The same wire that goes to your points.
The drive home was 'Interesting', glad I was in my 185,000m Discovery with decent AT tyres... we saw plenty of bashed up cars on the westbound M54,and several people overtook us on the way back to Brum.We chose to stick to about 22mph in the slow lane,
I think there may have been a few oppertunities for you at the show Wayne,seeing the poor quality and high prices on offer at a few of the stands....
I'll be there next year in a different mode
I think the road was clear by about the time we got close to Gloucester. Fairly fast run down to Somerset from there then I had to make my way alone to Dorset.
There was a convoy of Coaches determined to make life hell for car drivers. Forget the name on them but they were driven by inconsiderate morons.
Went more to just look around and meet a few people. Had a good chat with Vesty, Snr Greeves and a few other Spanish friends as well as a brief chat with Big John.
The drive home was a bit hellish! Left at 5pm ish, got back to Dorset 10 past Midnight!
spot on Wayne about a mile up the road..Yate Court.Funny enough I put a "quiz pic" of me in our local gazzette from 1979 (c 30 years ago) at this venue trying to identify the two guys looking on. http://www.wessex-centre-acu.org.uk/ if you want a "rare "shot of me with my feet down..te he..
Nice period photo.
I wish I could remember names from that time but I dont. I lived in Yate for quite a while although I was from Iron Acton originally.
There was a family running a couple cotas who lived the end of Stanshawes drive in Yate. The lady there was my postlady I think! Your video's reminded me of that.
For anybody who wasn't there this was our first Ctr. Champs Trial on no stop rules.....think we got away with it. Many Thanks to Fraser Dicken for getting it done so fast .we hope to have some "comedy" edits for dinner dance and names /captions etc along more vids.
sorry guys this is self evident but the one below works & is next to it.
and a bit of the little ones
Been a long time (nearly 30 years!) since I rode out that way, isn't that nr Yate Rocks?
Help On Front Hub Identification Please?
in Bultaco

Probably a Pursang hub.
