Does everyone know if the 1977 DT100 came with a emissions sticker. The research I’ve found is the the government didn’t do emissions for the DT100 till 1978. If there is one. Where would it be?
Is there any documentation/pics of a original 1977 Yamaha DT100. I’m looking for detailed pics from front to back. I’ve looked at all the documentation, assembly and parts manuals. And I think I’ve watched every YouTube video on the DT100. I’d like to restore my bike back to original as possible…
I agree with everything you’ve said. Maybe this would be a good time for anyone that has a ‘77 DT100 to post pictures of their bike. I’ll post a few before I start working on it…
Does anyone know where the crankcase breather hose is routed too??
Found the breather on both sides. I’ll get some tubing and get them hooked up. Thank you for the pics and info Devin…

That is correct. No emissions sticker was used on the 1977 Yamaha DT100D. They did however use the battery sticker, located on the rear fender, under the seat. that sticker can be purchased here on the website or on the eBay store. We also have the emission sticker you mentioned for the 1978 Yamaha DT100E for sale on site/Ebay. All of the DT100 emission stickers from 1978-1983 were located on the rear fender next to the battery sticker.
In 1969, Yamaha released the 125 and 175 enduros. Those models were released in the USA every year, until 1977. Due to the new EPA regulations no 125 or 175 Enduros, were released that year, in the USA.
The USA GT/DT80 80 models were made from 1973-1983, but just like the 125 and 175 enduros, they dropped the enduro 80 model in 1977 only, due to the new EPA regulations.
