Vintage Project - Yamaha DS7 - 250
Vintage Yamaha Project…
So another journey begins. This bike landed in my garage mid 2017. There are a couple connections here that make this more than just another project for me. I’ve shared a couple pictures here and there of this, but I figured I’d get a build thread going to keep track of the project.
Official “Before” picture.
Background. This bike belonged to the father of one of my very good childhood friend. Shawn’s dad, Ray, purchased this bike to use a farm runabout. The story goes that it stopped running one day – sometime in 1976 based on the license plate on it. Ray tinkered with it a bit, then parked it. It has been bounced around in the family the past 40 years, landing eventually in the tool shed on the family farm property that Shawn built his current home on. Ray passed away last year.
Shawn and I had talked about the bike a couple of times, and eventually it ended up on my trailer and in the garage here. It’s a 1972 Yamaha RD250. It has 3614 miles on it. So on top of the sentimental value, it’s my ‘birthday’ bike – it was born the same year as me – 1972. So there you go – birthday bike, that happens to be a Yamaha, that I know (or knew) the owner.
Winter set in here in Michigan and focus turns to projects like this. The bike is amazing complete and unmolested. There is rust. There is dust and dirt, as well as some rot. With a battery booster pack connected, the lights work. The tires hold air for about 10 days before going flat. The switches all seem to work, the motor will turn over with the kicker and the transmission will cycle through the gears up and down.
My first goal is to see if it will fire and run. The motor internals look pretty good – there’s fairly clean oil in the gear case, the oil tank was half full of oil. I’ll order some parts and see where it goes.
Current progress.
Box of parts from EconomyCycle.com arrived with new points, condensers, coils, hose. A battery and spark plugs from Amazon and a throttle / oil pump cable assembly from Ebay. The carbs have been off and gone through a cleaning cycle in an ultrasonic cleaning tank.
I put the carbs back on and have the gas tank filled with vinegar to clean the rust out of it. Curiosity got the best of me the other night. I checked spark in each cylinder and the tester lit up when connected to each spark plug. I grabbed a can of starter fluid and gave it a puff of go juice down each carb with the throttle opened up. Switches on and kicked it over.
It coughed and burned the ether. Holy Shit! Repeated it and same result. I know not to do this anymore without some pre-mixed fuel in it (it is a 2 stroke). I realize this does not guarantee by any means that it will be a runner, but it sure does provide the motivation to press on with it…
More to follow…

Re: Vintage Project - RD250
January 24th, 2018 – update 2 – more progress pictures.
Seat, tank, airbox, battery box, rear fender removed.
Rear fender clean up.
Gas tank clean up. The tank had some rust inside it; most was pretty light. I let it soak with 2 gallons of plain vinegar in it for 2 days. Then rinsed the tank out with a baking soda mix to neutralize the vinegar. Here’s what it looks like now.

Inside of that tank is impressive. Amazing it wasn't far worse than that after sitting all those years. Vintage stuff can be a lot of fun to tinker with. Best of luck o the project!

Re: Vintage Project - RD250
My best friend's dad has an old honda dream 305 in his shed. It needs restored but is all there. Including the factory hard bags and windshield. If i ever get time for a project I'll be asking him about it. Looks like a fun thing to do.

Re: Vintage Project - RD250
Wow! My first bike was an RD400, so I can tell you the two-stroke RD engines are tough as nails. They also propel you and your machine to Mach 1 in about 30 seconds.
Will be following this with great interest!

Re: Vintage Project - RD250
Thanks for following along and the encouragement.
"Honey, why do I smell gas in the laundry room?"
Got ahead of myself tonight. Assembled gas tank and ran fuel lines. dumped a gallon of mixed gas in the tank. 40 year old gaskets do not re-seal once they've been cracked open. Petcock looked like a lawn sprinkler. Red-neck speedy-dry deployed (cat littler) and tank draining in bucket out back.
Petcock gaskets ordered...

Ancient history! You can tell an antique bike because it has an honest-to-goodness RESERVE gas tank.

Even older, this is a non vacuum petcock, so it has "on", "reserve", AND "off" !Uncle Hud wrote:Ancient history! You can tell an antique bike because it has an honest-to-goodness RESERVE gas tank.

Re: RE: Re: Vintage Project - RD250
Is there any other kind? I always hated to walk out to the garage when the petcock hadn't been turned off after the last ride. I also hated to have to turn the petcock to reserve when the CB550 coughed and quit at a 4 way stop...but I guess it's better than having it on reserve the whole time!extrememarine wrote: ↑Fri Jan 26, 2018 11:02 amEven older, this is a non vacuum petcock, so it has "on", "reserve", AND "off" !Uncle Hud wrote:Ancient history!

I also had to explain to my 17 year old GF in 1977 what a petcock was.

Re: RE: Re: Vintage Project - RD250
DRZ has a vacuum petcock - has "on", "reserve", and "prime" - prime bypasses the vacuum shut off.
It's especially great when you set out taking back roads to techday with half a tank of fuel, planning to fill up when you hit reserve. Fast forward to middle of nowhere farm country and bike coughs and stalls; reach down, roll petcock to what should be reserve and nothing happens as you coast to a stop. Further investigation reveals that the last time you filled up, you didn't roll the petcock off reserve. Pushed that thing just a little over a mile to the gas station...

Back in the day we would back up into the ditch to fill the float bowls. Sometimes leaning the bike to the reserve side got where you needed to go.
