Mid 60's Bultaco Matador Project

[stainlesscycle]

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.

Looks good. A little soda blasting of the carb and fire in the hole!

Good job! Looks great!

Where have you been getting your bits from? Esp Engine bits (rings etc...) I have a 68 Pursang I am wanting to restore.

[tenorjazz]

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:



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.



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





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.

Sweet, nice job. BTW what powder coating unit are you using?

[PSchrauber]

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:
