    My personal No. 1 street Bultaco, F A N T A S T I C color scheme! :clap

    Only OK to mint, seat doesent fit, gaps, no logos, ...

    No. 2 street Bultaco, because the color scheme shown in first pic is better!

    Nice but not first when it come to Bultaco cirt-bikes:

    [/QUOTE]

    Bultaco Sherpa Kit Campion A model 80 I believe this is my personal No. 2 of the dirt-bike's from Bultaco, a real beauty.


    Also nice a little earlier or may be aSherpa model 80 too, but without the Kit Campion", I'am not so keen on the early ones. A nice bike but not number 1 somewhere between 5 to 3.

    Sadly my personal No. 1 is missing the 198b or 199b, (first series build only in 1981 not the later ones that where assembled using the left over spare parts after the bankrupty of Bultaco)

    [​IMG]

    This is the only bike IMHO that can wear the blue white color scheme, sadly the lamp mask is missing and the rear shock is something else then original. Here is one with a lot of scratches but in original used status:

    It's interesting to read PSchrauber's comments about the various bikes pictured here, but I don't understand the comment: "not number 1 somewhere between 5 to 3".

    It makes me wonder what other opinions are about restoration or rebuild projects in general.

    There are marks for restauration, but the marks I submitted where more personal. (*)

    With somewhere between 3 and 5, I only wnted to express it's not my personal number 1 not even number 2 depending the dirt bikes Bultaco made. In my personal order it comes between 3 and five. There are others that a

    Or in my personal view dirt bikes Bultaco:

    #01 model 199b amd 198b
    #02 model 80 with kit campion
    #03
    ... the other Dirt Bike Bultaco is somewhere here
    #05

    I probaly have a certain connection or tie wehn it comes to numbers, (has to do with my profession I think, (not so interesting in this matter and therefor not worth here to mention)).

    (*) Restauration Marks in Europe, (in short, I will not get lyric here:
    1 like new, in running and perfect technical order, (very very hard to get)
    2 minor visible used marks, in running and perfect technical order
    3 visible used marks, some small corrosian, in running and good technical order but nothing worn out or missing
    4 corrosion marks, some parts missing, some technical failures but still running
    5 below 4

    To my opinons in reatauration this is difficult, here I personally divide the old bike world between street and all purpuse or light enduros and real dirt-bikes that where made for motorsport.

    Where patina is great for street and all purpuse ...

    You have dificulties to restore them to sporty dirt bikes.

    In my opinion sporty dirt bikes will be used to their limits they are build to be competive so all parts and components are build to get out the maximum of speed, power, suspension, weightloss, ...

    These bikes are not build to last they are build to win and to be regular maintained, there has to parts swapped, ...

    When these machines getting old and are not competive anymore many of them get abused, no maintance, .... just ridden until something breaks down and the bike does not work anymore.

    Then it will be stored somewhere until a fool like me comes and try to get that thing running again. If you ant to get it in a good running status than you have to change out so many parts that again it is nearly like new.

    With road bikes there are not so many differencies between new machines and yesterday beside the older one's are not so fast, don't break so good and the suspension is also only as good as the old bike accelerate. But still you get from A to B.

    (In short I hope this is somehow understandable)

    my faves are all the race bikes...
    pursangs, astros, sherpa s...
    the later sherpa t's (like 198's) were their best trials bikes...
    the frontera's were probably their best enduros...
    i still have a bunch more to build - i'm in the middle of a 134 project, but have to build an early lobito 125 that i'm putting a 167 motor in and making a street bike out of it...should be a rocket... and i have 2 more 67's and 2 68's to do.. i'm always looking for parts bikes to cobble together...

    Well that Lobito should be a neat bike! I would caution that if the bike has a rubber bushing in the swing arm the handling can get a bit exciting when ridden in "maximum attack" mode. In normal riding the bikes are excellent handling machines. With the 250cc motor my guess is you should be able to pull away from anything on a tight twisty road!

    The weather has been cold and wet, but today it was beautiful.

    I got my piston installed and mounted the cylinder and head. Then got the magneto cleaned up and pretty much got everything together.

    Here's how the motor is looking:

    I need to clean up the carburetor and get it installed, and that should just about do it for the motor parts.

    I need a couple of clear days to sand blast and powder coat the frame, because I have to do it outside. So I'm going to hold off on the carb for a the next couple of days and see if I can get the frame done.

    I sand blasted it this afternoon and will clean it up and prep it for the powder coating in the morning. Hopefully I'll have it done tomorrow.

    You should be able to get what ever you need from Bultaco.com or BultacoParts.com. But you can get things like seals and bearings locally or on the internet. One place someone mentioned was www.vxb.com, they seem to have just about any kind of bearing you could think of.

    I powder coated the frame yesterday and it came out good. Here's a couple of pictures:

    Loks very very good, it's astonishing in which good status overall your carb still is. It looks like there is only little wear at the slide, this is very astonishing too me. The carbs I found mounted to my old bikes where
    mostly wrecks. slides worn out, screw heads damaged. The carb full with whitch gas layer, ...

    The powder coating looks got to, where do you "burn in" the powder, do you have your own room for heating up?

    That Carb is a national treasure! I saw it on a shelf when I picked up the bike and casually asked if I could have it. The owner hesitated then asked if I knew what it was worth. I replied about $300. He said take it, you will need it! Score! I checked out the work today and all looks very nice.

    I've been a potter for almost 40 years and I use one of my pottery kilns. With it's "computer" control, it is perfect for curing powder coating and the temperature you have to go to is nothing for a pottery kiln.

    Worked on the shocks today and also powder coated the tool box.

    The Bultaco shocks I have are not in very good shape. I'm going to work on them later to see if I can rebuild them, but for now I'm going with these shocks from a 1970 BMW. Here's what they looked like when I started:

    [​IMG]

    I was hoping I could open them up and powder coat the main cylinder, but these are permanently sealed. So I cleaned them up the best I could and powder coated the spring. I still want to powder coat the end and the adjuster black.

    [​IMG]

    There is still a little clip I need to do on the tool box, but this is what I have done so far.

    [​IMG]

    [​IMG]

    I was curious how things might look together so I kind of set things up. Looks like I got the carb throat on upside down, but I didn't think it would clear the tool box the other way around. I'l reinstall tomorrow and see if that works.

    I just took a look at your front sprocket it looks a little bit worn befor you assamble a new chain, you should change the sprocket too. You get them from Talon in Britain. (And don't forget the security plate).

    To your positioning problem, I 'am not very sure but Bultaco's had already very early a rubber tube between the intake and the carburator mounted,
    maybe your intake is a very good "add - on" from any virtuous machanic.

    My Sherpa has this gooseneck type intake that allows the carb to be mounted higher, with a rubber tube between and upright too.

    But as already stated I 'am more keen on later Bultaco models, from the begiining 70's to the end.

    Just found out that your intake must be right.

    This two year younger Matador had the goose-neck intake:

    The 66 model here has the same intake:
