[Vintage DT250MX]

I am an Englishman in Poland. I know that PS tuning in Holland can make it for me but I don't have a pattern for him to use. If anyone has a 77/8 DT250 exhaust that he could use as a pattern, that would be an option.

Otherwise I guess that the only other option will be to wait until the bike is back together and take it to him on a trailer

[Dt250MX exhaust systems - fancy a new one?]

Does anyone know if the DT400 exhaust is the same shape as the DT 250?

According to the parts manual they have different pat numbers

I have spoken with Peter at PS Tuning and he has a pattern for the DT 400 but not for the DT 250.

Otherwise if there is anyone in Holland/Germany who has a '77/8 DT exhaust that Peter could borrow to use as a pattern, that could be another option.

I would appreciate any help offered.

['77 DT250MX airbox cover]

I am renovating a '77 DT250MX which was one of just 450 specials supplied to the Danish army.

It has uprated front forks and an extended fuel tank as you can see from the picture.

I have been able to source most parts that I need but two items are yet to be found, namely a complete exhaust system and the side cover for the airbox which when it is available is at an astronomical price due probably to their scarcity. So I have decided to try and make one.

I have the air filter end cover which is held onto the airbox with 3 screws but what I need is a clear picture showing how the outer cover is attached  to this inner cover. It looks as if it was with some sort of rubber hinge but I would like to have details of this. So if anyone can take pictures and either post or send to me direct it would be greatly appreciated.

Here is a picture of my bike as is and another of how I hope it will look when finished

Would anyone  know of a source or manufacturer of a complete replacement exhaust system made to original shape for a 1977 DT250MX??

Your thoughts gentlemen or even can you point me in the direction of someone who is already doing this so i can place an order for one. It way well have been done before and i di not want to reinvent the wheel

 

Ok then. I may well have found someone who would manufacture a system for the DT250. I have looked long and hard on fleabay and literally 100's of sites for the system to no avail, they really do seem to be as rare as rocking horse poo. Assuming i am not as dumb as a box orf rocks and there is someone sitting (uncomfortably) on a pile of dt 'spannies' and silencers and i am the only one who does not know about them then;

 

Q1: If i could get someone to manufacture a pattern system based on the stock system would anyone be interested. Likely the more people interested then cheaper that will be.

Q2 If i could get someone to manufacture a performance system (fresco-a-like) would this be of interest.

Q3:What would people be prepared to pay? I am not looking to make money out of this but do know what value people would place in a new system v.s the cost to manufacture. I understand that realistically the first /prototype will be the expensive one and then the following ones will be just time and materials. I think getting together an order of 20 or so would make it worth while and cost effective - that is a back of a fag packet guestimate.

 

Well Zohan, did you ever find a source of an exhaust system for your DT250MX??

I have a '77 ex Danish army model and I need the complete exhaust for my project. I don't even have a pattern except a stainless pipe that someone made for it sometime. 

I want to restore to original so I have to find one somewhere.
