I just completed a restoration on a 1978 Yamaha DT400E "Rumble Bee". I will be deployed and wont be able to do much until 2020 but wanted to make a place holder for my next restoration's.

I saw this bike on Ebay. The bike is really interesting compared to what we had in the U.S. I wont go over all the parts break down but its a combination of 1978-1981 parts and also has some Euro specific parts that we never saw in the U.S. The bikes owner was in Greece, and told me that many were crushed/destroyed, its a shame. Due to overseas shipping I only purchased the frame with matching numbers engine, plastics, rack, swing arm, etc. the rest of the parts I already have.

It was interesting to see that other countries had many different color combinations for the same model (Sometimes up to 4!).

Gr8uncleal late for work again! Oops, that's his boss he's just jumped over!

The car looks like a Ford Cortina mk IV or V (correct me if I'm wrong here fellow Brits) and my dad had a brown one.

For those who can understand German, here is a picture from the German Brochure and what looks like an inspection checklist.

The European and US model shared the same exhaust pipe but the silencer on the USA model was different. The European’s model was not as restrictive, because they did not have to meet the EPA’s emission standards.

Below is the Euro model

In 1978-1981 The pipe business was not supported for these bikes in the USA. Bassani, Hooker, J/R, etc were big in the previous years. There wasn't much you could do to improve the exhaust system other then a sleeper pipe or custom fab your own. In Europe however, a company in Italy offered an aftermarket exhaust system. It is called the "Big One". They did not offer shipping to the US, so it was impossible to get unless you knew someone in Europe who would act as a middle man.

This pipe and silencer is now being sold by Yambits! It took 3 days to arrive and it was shipped with FedEx tracking. The box was very sturdy and it was packaged well. I have included a cost slip, it costs about $255 for both the pipe and silencer shipped to the USA.

Great stuff Devin!

One thing the Euro bikes might not have had was the USFS certified spark arrestor in the muffler that is pretty much required on the trails anywhere in the USA?

Good point Mark, they probably would not allow it. I wonder what they would think about the big one on the trail’s, I would think it would be comparable to the the FMF silencer’s. I heard in California they actually shove a rod in the pipe to check.
