My dad had this bike since the 70s, and I have memories have him taking me around the block on this bike. Now that I'm of driving age, I've been wanting a bike of my own, but don't have money or a license for one, so I decided to get the Yamaha running. I started this a month or so again, but I figured someone might be somewhat interested, and I figured this would be decent way to document progress. This isn't so much of a "build," but more of me getting it running and I'm safe driving condition.
So, this is my dad's 1978 Yamaha DT400, street legal dirt bike.
Since it hasn't started I'm 3 years, I took the carb off and brought it to a buddy at work that is good with dirt bikes. He was pretty amazed at how dirty it was, and was more surprised at how well it cleaned up. He got bored and took it apart at work and filled the bowl with carb cleaner, and this was the result.
I threw the carb on and my dad tried kicking it over to see if that'd be enough to start, unsurprisingly, it wasn't. We noticed the filter wasn't getting any fuel, and decided the petcock was clogged. I had to replace the fuel system on my truck, so the bike was on the back burner for a while.
Yes, I know I need a belt, but these were just some work clothes, and my appearance wasn't really a concern
Now that the truck is running, though, I orders a new petcock, and took the old one off. That was definitely the problem.

Clogged strainer
While I have everything off, I'm going to take the fuel lines and filter to Napa to get replacements. Also on the list are new tires, the originals are still on it, new spark plug, battery, and possibly a carb rebuild. It probably should be rebuilt regardless, but I'm going to see how it runs first.
