Thank you everyone for all of your helpful information.

Do the Inmotion ones fit correctly, better to stay with the original loose ball bearing type otherwise.

Good luck with your new club and first trial Jon. Website worked ok.

It is a nicely built one off from a 198a in need of renovation.

When looking through posts here in the Bultaco section for information on availability of a bearing kit to fit taper roller head bearings to the Bultaco Sherpa 199a I saw Pyramid parts mentioned as a supplier but when I contacted Pyramid they had no knowledge of the correct bearings or the part number. Presumably the taper roller conversion is a satisfactory improvement. Does anyone have any info on the bearings or a part number for Pyramid please?

I think the swing arm is from a 199b model Bultaco not modified in any way.

To the best of my knowledge all the Beta Rev 200 models were based on the Rev 3 250 engine fitted with a 125 con rod and sleeved down cylinder, the Evo may have been different though.

A friend has fitted the Arrow one to his bike it fitted very well, gives a slightly different I think better sound and definitely increased performance.

Thanks Woody, do you or anyone here on the Bultaco pages know which blue paint is the best colour match to touch up the 199a please.

Thank you Woody

What carb to air box connector is needed to fit an OKO carb to the 199a, is the standard one that connects to the Bing useable?

Inmotion have the correct nut and bolt they are a metric fine.

The VMCC run numerous trials in several areas of the country where you could ride your bike, why not enter those? How about posting a photo of your bike so that we can see the differences between it and those pictured above.

Of course there will be NO damage to the ecology or environment by building HS2.

http://cemoto.tripod.com/bultaco.htm You need to go through the model list above they are all shown.

Use the AJS wheels with their brake plates and alloy rims.

The brake plate goes with the hub, what do you mean?

Bisby in real life George Formby was a motorcycle enthusiast and I believe rode Norton, in the film he called himself George Shuttleworth which is why the bike he supposedly built was called the Shuttleworth Snap, I think it was built around a Triumph Model P. The race bikes doing the most winning around that time were the Marston Sunbeam so Sunbeam became Rainbow in the movie. Charlie on second look the forks are Triumph like so a pre-unit twin from Triumph it could well be?

It possibly depends on which club you will ride with but why not it is a genuine British made hub.

Is that an attached sidecar under the sheet if so it must have been at least 350cc but likely bigger, appears to have a single down tube frame but not much else to go on. It should be you telling us what it was surely?

Which brake lining material did you get from VS for your Bultaco hubs, I am about to send some shoes to them.

Most British and Spanish bikes use 3/8" / 10mm diameter cable nipples while Japanese bikes have 5/16" or 8mm barrel nipples.

Worth remembering though a bike that looks right does not always run right, rebuilding a trials bike is more than a shiny finish if you decide to ride you need one that works properly.

My advise is to keep the parts to each bike completely separate to the other then build one using its own pieces borrowing nothing from the other bike. The knowledge gained from the first can then best be used on bike number two. Are you building them to ride when finished?

Quite agree but buy a good grease gun, these are excellent...http://www.alemite.com/catalog/details.aspx?identifier=guns_standard
