Are you overseas, bloke-types familiar with Hugh's Bultaco in New York?

He has a huge stock of NOS and used parts.

He scours the world for this stuff.

I remember selling him a pickup truck load of Bultacos and parts about 12 years ago for $200. Aaaahhhh...the good old days!

I guess trials stuff is always scarce, though.

I always has lots of Alpina and Sherpa S stuff.

Nice for a change not to be replieing on ACU matters. perhaps I should concentrate more on things like this. I have specialised in ecerything Bultaco for some 30 +years

re - plastic tanks.

Paint : Some of he guys I sell Bultaco bits for in Australia tell me that the trick is to coat the inside of the tanks with one of the resin basd products ( not sure which one - will try to find out) - that are used mainly to stop leaks. This then sort of seals the tanks - and the spray job on outside works far better.

I have several of these tanks - all blue)- do not really wish to sell the good ones - but may have a few with the tap damage that Nigel reffered too. Will try to have a sort out soon ( sounds easy but we have literally tons of Bultaco spares)

I too spent many an hour fixing these - and eventually came up with quite a good method.

I do have one I would sell - but the idiots remedy for tap repair was to cut out a large ( and I mean large) section of the bottom of the tank.

i put it to one side in case a welding technique ever came up to repair ( about 6 inch by 1 inch cut out)

Will post some info when I have seen exactly what we have.

Tap turnaround was one of the mods we always did regardless of metal or plastic tank. The other 73 mods I will post when I get the list out.

The plastic tank mod we did was a little mre sophisticated and involves a metal plate replacing the captive nuts inserted through the tank filler cap, works well.

Agree with Nigel - always best to turn the tap around - try to remember on/off is opposite way - before you head hell for leather up a big hill!

Re - repair. I usd to make a plate - to fit into inside out of metal about 3mm thick. Cut and file slot in middle to allow tap centre/filter to pass through - Drill 2 6mm holes in screw position - and then either tap 6mm - or better still braze 2 6mm nuts ontop of holes. You should now be able to attach your tap to your plate and see if everything lines up - and screws thread in correctly - use slightly longer screws.

To fit plate I used to attach it to a welding rod - lightly - and then use the rod to manouvre it inside the tank - until it lined up with holes etc - I aslo made a gasket to fit on outside ( you could use O rings - but I prefer gasket and some sealer. Once lined up - insert and tighten screws - then wiggle the welding rod which will soon snap off plate - and job is done.

Lately Y kave had a few problems with Gas Gas tanks - but have not tried the above on them yet - but fear it may be soon

John Collins: I am assuming you drill out the existing nuts and plastic "humps" the nuts fit into? I have a good friend with a '79 Sherpa T and have attepted repairs with hot glue to no avail. This metal plate fix is definitely in my future so any further tips would be appreciated. Thanks, Jay Lael

Sorry bob can't lay my hands on it but give me an area of the bike you aren't happy with and I'll try to remember a few, as a stopgap.

Jay, did you get the package ok?

I used 6mm plate aluminum, followed johns method and passed the plate down on a stiff wire filler cap to tap hole.

Holes drilled of course. 1 bolt into plate,2nd bolt through tap into plate then 1st through tap into plate and tighten. From memory used the o ring, as they seemed to seal ok.

Any help? :D

Thanks Nigel! Yes it's clear to me now. Yes I got the package. Many thanks. What I have done is placed the T&MX news in the loo at work. Get to read all about far away and exotic locations while on the, er well indisposed. I especially like the brochure from the stadium trial. The photo of Mark Friexa looks almost like me.

... next step will be to find a set of the extra long works shocks (I think Lane L started the trend and I think they were Fox shocks - by the way where is Lane these days?

anyone have a pic of these shocks? Just bought a 199b that's very high at the back??? shocks are anodised red with no logos or markings- very plush too

have a look at this - http://www.motocra.com/Bultaco.htm

could this man have any tanks ??
