Thanks Steve, much appreciated. ?

Alright lad, I going to go at this from a different angle, as I find your response confusing and I fail to understand it! My dilemma is as follows, I recently purchased a new airbox and when I attempted to bolt the seat on top I cannot get it to fit properly without squashing the tallest snorkel. Many thanks. Pat

Best I ever got out of mine in competition was 38 miles, before I hit reserve.

I'm afraid not nigel me ould pal. Call me thick or what, but there you! As someone with a far better grasp of things said once, " a picture paints a thousand words".

I'm afraid that I don't have either parts book to hand. However based on my knowledge of Bultaco parts books, I can almost be sure that these parts will have different part numbers. Can you be a little more specific? As the hub, brake plate, spokes, rim etc... will all have bike specific part numbers.

Would anyone have a photo of the 199B airbox, showing the snorkels? Thanks

A frustrating evening in the garage! Started off with two "simple" jobs to do this evening and ended up accomplishing neither. Decided to put new swinging arm bushes and inserts into the 199B and ordered the nylon/plastic bushes as I felt they be the easier to fit. The bushings and inserts fitted the swinging arm like a glove, the fun began when I attempted to marry the swinging arm and the frame. Needless to say after many attempts the swinging arm remains unfitted to the frame. Will have to now spread the frame to make it wide enough to accept the swinging arm complete with bushes and inserts, I reckon a car jack should do the trick. Following all that trauma, I deceided to fit the new airbox I received from InMotion. Now all looked well, however I noted that drilling would be required for both attachment to the frame and the fitting of the side panels. I also noted that no side panel gromets are supplied with the airbox. Anyway it is almost fitted at this stage My question is does anyone have a photo of a 199B airbox as I would like to see how the snorkels are arranged on the airbox. Many thanks in advance.

Well after a number of false starts, I finally got the frame away to the powder coaters, collected it today and I'm delighted with the finish. Of course as soon as I got it home I couldn't resist fitting the bash plate that I got from Todotrial. Which fitted perfectly and offers way more protection than the original. Next on the list will be swinging arm bushes and a new airbox.

Out of curiosity, can I ask why you need such a large amount of information? Are you restoring multiple Alpinas or writing a thesis on Bultaco Alpina frame geometry ?

If you want to realise the highest possible price for resale, get it professionally stripped and powder coated.

Bondy, would you have the torque setting for these?

Here is a link to the tank in question. It looks a well made item as I saw one close up at the Telford show back in February. https://www.inmotiontrials.com/product/sherpa-alloy-inner-tank-fiberglass-cover/ Bear in mind its listed for a Sherpa, so it will have a smaller capacity than the original Alpina tank.

Back in the day when I worked for the Bultaco importer in Ireland, we never received a parts manual for the 199B. We used a generic 199 manual for ordering parts. No technical bulletins or spec sheets were ever received either. Unfortunately this was one of the many side effects of the pure chaos that was going on in the factory for 79 to 83.

Amazingly enough the original Marzocchi rear shocks are still on the bike,unsurprisingly they are completely siezed solid. So I got my hands on a set of Betor gas Shocks at Stafford today ?

Thanks andrep I'm looking forward to the build. A selection of parts now ordered from a well known Fantic specialist. Thanks Bob you're a gentlman to deal with. ?

Simply could resist myself! When to look at this one yesterday and thought to myself it won't be up to much, so I didnt bother with the trailer. I was pleasantly suprised at the bike when I saw it and before Iong I was dismantling it to get it into the back of my car.

Some of the early production 199's, did indeed have fibreglass tanks. The factory then switched to poly tanks for the vast majority of the production run. Often thought that the fibreglass tank looked much nicer, as the paint made for a richer finish than the matt red finish of the poly tanks. But I know I much more prefer a poly tank when riding in actual competition, as the fibreglass was prone to damage. Sold a good few replacement red poly tanks back in the day, to let us say, the more "enthusiastic" type rider!

Thanks bullylover, apologies for the slight confusion on my part, as I should have said; "Any advice on the type of Main Bearing to use, ball or roller?"

Have a browse through the following link, a interesting discussion of which oil to use developed during it

Yes, it became a magnificent restoration job by Gilles Escuyer. On my own 199B, I had a good delve into the engine today. It all looks fairly decent, good compression, smooth clean bore etc. I will put in new bearings and seals, as it has been lying up so long. Any advice on the type of bearing to use, ball or roller?

Channel 5, show it on the following Monday evening at 7:00pm

Thanks for the advice nigel dabster. I campaigned a red 199, back in the day and I'm more than fully aware of the difficulties that I encountered firsthand.

Thanks Greg, I have the forks, I'll get them hard chromed but otherwise they're in fairly decent condition . Have the top and bottom yokes as well. Yes, as you say they're a grand simple bike to work on.

Sure each to their own My own direct experience of Bing carbs, were mostly down to rapidly wearing Slides and sticking float valves. Not only on Bultaco's but on Maico MX'ers as well. My respect for Mikuni carbs is borne out of never having go near them through several models of YZ125's and 250's. My reason for favouring the Electronic Ignition system is based on the positive feedback I have encountered from a number of people I know who have fitted it to their own Sherpa's.

Thanks guys for the kind words. Yes, it's in a bit of a state alright, but its all repairable or replaceable. I made good progress today, got my local welder who also happens to be a big Bulto fan, lined up to repair a cracked tube in the frame. Also have the frame, swinging arm and rear engine bracket booked in for medium blasting and painting. I have now got everything catalogued and a list of spares that will be required. Luckily I was just about to start a 199A restoration before the "B" happened along and I had already acquired a lot of spares for that restoration. So now I just basically need is a new airbox, side panels, saddle and a pair of white mudguards. Unfortunately my poor old 199A will have to say in hibernation a bit longer until I've got the "B" up and running. The plan for the moment is to work on the frame and cycle parts, get that all sorted and assembled, then delve into the engine and gearbox. Will definitely go with electronic ignition and use the Mikuni carb I have planned to use on my 199A. Ironically both bikes came to me without carburettors, no loss really as I was never a fan of the Bing carb, way to fragile and finicky in my experience. Will post up photos every once in a while as progress reports.
