i have been working on this for a bit, but must knock on now so thought i would show a few bits i done..

As you can see, some of these i have not done them as well as i could, and the reason for this is the bike is going to be my first go at trials, so its going to get abused and on top of that i did't want a bike i would be scared to use.

The bike is all there just needs bearings and a tidy up as well as a bit of welding and its on to the paint.

Doing the forks at work in the next few days and will hopfuly put a pick up.. next is the swing are which i have removed the bearing and need to get new ones. then paint for that and the frame..

forgot to say the bike is a sherpa t model 150 slimline 250. the year is 1975

The top and bottom yokes are painted because they was in a bad state and to polish them would have took to much off them. The bottom of the forks was pitted and had deep groves in them. Also i want to use and abuse the bike, and the paint on there being aero/space will stick most anything and any weather. The brackets started of black as i was going to do the bike in the red and black paint job. . only because i could get the paint for free... but looking at the bike again i desided to do it in the same silver and blue with most of the ally anodised..

In all i cant follow the rules and make it how it was, as it has lots that need doing.. but i can still make it a very nice and tidy sherpa that i'm not afrade to use. A few years back i had a gsxr 7/11 streetfighter which had all its ally polished, and to be honest it was a nightmare.

I do all my own painting and anodising so just a good loooking bike will do me for my first time at trials.

Hope this helps anyone that has been looking and if anyone needs to know anything feel free to ask

still doing bits and bobs as you can see. bars and rims are going to be black anodised

for the time being. The wheel spindles have been treated and plated and the threads have been coated in

dry film lube. the rest of it it just tarting up the paintwork.. still waiting for the

swing arm to be sorted. then its that and the frame..

still trying to get as much done as pose. this is the air filter as it was, bit rusty

and the paint was flaking off, the spring and plate was rusty and the sponge was breaking up.

This was done today.. been blasted and had a few coats off primer and loads of paint,The plate under the filter sponge, and the spring have been stripped and plated as well.

i could see these getting covered in mud all the time so both paint and plating are

over the top as protection, and a new sponge was added.

hope this might help. i have only stripped the bike and do not know the history or anything about it. the engine and chassis numbers are the same, and its a 1975 model, 150.. 250 slimline. and thats all i know realy. its not a bad bike and i got it cheap to do up and to use for my first trials.

The more i look at this now the more i think i'lll change it. Would't be over hard to make a T piece

and a bar from the T piece that would bolt to the head and a bar to go from the head to the frame..

Have to leave this one with me for a bit...

hi again i dont think you have the right fram for the engin seems weirod theres somthing wrong somwere there is only to typs of headsteadys one for the 350 witch i have .and one for the 250 both look same but there not the to holes witch fasten to the head are diffrent closer together on the 250. and wider on the 350 the lenth is the same i think not 100% sure but if your saying the frame. and engin numbers match it must be the right frame. hope this is of help

i just sorted out the paper work and the engine and chassis number are the same. as well as checking the frame and engine.. It's not a great problem as i'm keeping the bike for myself. as long as its 90% i'll be happy with it, and the few bits that i have done i'm happy with.. so i'll keep building and improving it.

i'm working on making a new engine steady this week, and the frame does need work, so the little changes i'll be happy with.

if anyone can tell me how long the head steady should be i would be grateful..

Hello zoolord, If the headstay you have fits you should just measure it, it will be the correct length. There were many lengths of headstays on Bultaco`s as the Pursang ones were different from the Sherpa`s of the same year. Different models had different lengths. Bully Lover.
