    Where would I find a wiring diagram for a 79 250 Alpina with a 5 coil mag stator?

    I have owned my m49 for over 8 years and have always liked the way it looks and rides... When I could get it going! It has generally been a right pain. I put this down to the fact it was getting on a bit and one day I would give it a good going over. Well this week that day arrived. A heap of seals, bearings and gaskets beside me, I stripped the engine. I didn't think that there was much wrong with the bottom end apart from an annoying oil leak from between the crankcase's. After replacing all seals and bearings, it was rebuilt. It had a rebore a while back, but hasn't been used much, so I used the same piston, barrel etc. The amal was put in the cupboard and a 24mm oko w…

    I recently picked-up a smallish Bultaco...a Campera, which came equipped with a very old Amal. This fifty year old device just did no do this bike justice. At first I was not sure if the problem was with the ignition of the carburetor. Since the carburetor was obviously well past its prime, I opted to look for an oriental replacement. Enter the Chinese Mikuni. Attaching this carburetor to the Bultaco was relatively simple...once you figure out where to get the pieces. It transforms the motorcycle. It now idles, accelerates without hesitation, and runs cleanly at all speeds. However, it is reluctant to start...either when it's cold or hot, so I still have some work to do.…

    Was doing a bit of a clear out over the Christmas and New Year, basically making room for some ongoing projects. So amongst all the usual bits and pieces I unearthed my original Owners Manual from my very first Trials bike, my 199 Sherpa T. So I put it aside carefully and said I'll have a good at that later. So I'm leafing through it last night and what do I find only the original Certificate of Date of Sale, which I didn't know was even in it. As you can see the bike was originally sold in Oct 1977, I bought the bike from the original owner in 1979 and kept it until 1985, current whereabouts unknown. As you can see from the photos below, it's a very early Sher…

  6. Hello! I have two old Sherpa T's that are in very nice shape and as far as the body work goes, and as such I would like to pull the original body work and preserve it while ridding with non original body work, but both tanks would be in need of repair to be functional as one has a crack and the other is missing one logo and has a hole. so my questions are, would the tanks be worth preserving at this point? I have all of the original paperwork, tools, bags, accessories, etc with them and can see how even having the original tanks would be a plus, but with the damage would any reasonable person here share that view at all? If not I'm inclined to simply repair the tanks an…

    I learned to ride on a TL125 and have had various twin shock trials bikes over the years,but never really trialed seriously.I,ve done maybe 7 or 8 trials in the past 15 years.I have never thought that the suspension was real important on my trials bikes.I want to get a bit more serious about it (twin shock) so I,ve been trying to learn as much as possible. I saw the two Santigosa Classic trials clips today and noticed the black Sherp T. I,m sure a lot of it was the rider as he seemed to be very good,but it looked like his Puma Sherpa worked really well,especially the suspension in the rocks.It seemed to me to work better than most the other bikes. Oh,and for those who…

    There seems to be a lot of photos showing very clean Bultacos on engine stands. Nows the chance to prove you get 'em dirty! Lets see your action shots. I'll kick off with a couple from last weekends Jersey Classic & Modern Trials Club 2Day. Which incidentally was an extremely well organised event, with top names including Steve Saunders, Mick Grant, Becky Talbot nee Cook & Ross Danby.

    Hello, I’m trying to adjust the clutch on my bultaco sherpa model 92. When I try and screw and nut they’re very tight, but also the whole clutch system spins with it. How can I hold it all still so I can loosen these and re set them in the right location.

  12. Hi all, I wonder if you could help me with my 2 questions below... 1) I am currently finishing the full restoration of a model 150 Sherpa T 250 and got the engine running today after installing the (new style) electronic ignition from Dave at Bultaco UK. The bike starts, idles, revs and runs really nicely - the problem is that when i blip the throttle the revs don't drop back to idle as quickly as i would expect. After each blip, the revs drop gradually, slowly settling back to normal idle - it may only take 1-2 seconds, but it doesn't seem quite right to me. - I have had the engine fully re-built by the guys at Bultaco UK, so it should all be sound - The throttle se…

    First of all----- It runs!. Put the new OKO on tonight and started first prod. Seems to be set up OK but I guess I need to ride it to really find out. The real question is what can I use to seal the air box to cover in the 183 model ? The original rubber is rotted away and I can't find a suitable replacement, any suggestions ?

    Can anyone suggest a source of some appropriate tubing that will bend from my airbox to my carb? I've had a mikuni on the bike for a while and I'm using a generic small filter but I'd like to fit the airbox, as I have it.

    I just inspected the clutch on my 199A and found that the clutch plates use no friction material, just steel on steel. They were in pretty good shape so I put it back together with 75wt synthetic gear oil and it works well. I'm just wondering if that is the original type clutch and if there are any special oil recomendations for it. I know you guys will know.
