what exactly is my bike model and year, and is it genuine? #1
My 2 sons recently bought me a restoration project, it was advertised as a US barn find DT1 DT250 1973. When it arrived I discovered that the Frame number was DT1F -22088 and the Engine number was DT1- 22088. It has no wiring loom at all, no lights, indicators, ignition or even a battery. My dilemma is that I don't know what model or official year my bike is, so I can't start to buy any spares because I don't know if they will be correct. Does anybody have any advice. Many thanks Middy63

The text of the advert makes me think that you are in the UK? Welcome! from another Brit if you are - a few of us here now.

I have attached a link to what you need below - looks like you have a 1971 DT1E. A lot of the UK importers mis-describe what they're selling - nothing malicious, they just don't know!

Loads of manuals in the Tech Library and worth a couple of hours of your time browsing and searching through the forum for info and tips.

Also, post some photos of what you've got! :Useless :Useless

There are a couple of things that don't add up, the frame and engine should have the same number both should have the DT1F prefix.
It sounds like you may have a '71 model DT1E Badge tank model Mandarin Orange Serial DT1F-20101 to 45120

If so it will be a piston port induction model with no reed valves

I agree that it may well be a 1971 DT1E.

Apologies if you know some or all of this already, but here are a few tips for sourcing parts:-

Familiarise yourself with what the parts actually look like by viewing as many photos of original bikes, brochures etc as you can. A fair few vendors don’t actually know what they’re selling and so often mis-describe them. Also, new old stock (nos) parts may have been taken out of their original packaging, but put back in a different, incorrectly labelled one.

Don’t limit your search just to parts for your own model. A lot of generic parts (eg indicators) were used on a load of different models. CMSNL (in Holland) and Partzilla (in the US) are good websites for both buying parts and seeing which other models used that part. On either site, if you click on the part number and scroll down, you can see which other bikes that part was fitted to. The slight limitation on this is that their databases are limited to US models.

If you intend putting the bike back on to the road, seriously consider fitting a 6v voltage regulator. I have attached the Yamaha Bulletin on this subject below.

Some forum members are able to supply new original or high quality reproduction parts – eg DEET has, amongst many other items, replacement silver/grey sheething that covers the wiring, 6v regulators and I believe that he also makes brand new complete wiring harnesses/looms. Therefore don’t be afraid to ask here for any parts that you need.

All the best.

Alan

I am in Northamptonshire. I will put up some photos of bike once I've worked out how to do it. Cheers David
