- This 1975 Yamaha RD250 had been sitting since 1989..As long as I've been alive lol! It didn't take much to get this beast up and running, also now riding. I've definitely fallen in love with the RD's platform, from engine & transmission package to frame design, these things are pretty amazing not to mention they are big bike slayers. More to come on this and the rest of the collection in the future so be sure to sub for more content like this!

I'm glad I found this video! I have a 74 that hasn't been on the road since 78' . I needed some inspiration to get back working on mine.
That's awesome, Happy to hear another one will be back on the road! These Yamaha twins are way too fun to let sit around..Good luck with the build.🤘
My first street bike at 16 was a blue RD250, not a model you see much on.
Love it, love the sound, it brought back some memories.
Thanks,
Nice! I don't believe I've seen a blue one yet, glad you liked the video. There will be more videos coming soon for this bike, the rd350, and YDS7 250 we have!
@@WreckedRevivalThe “Butterfly blue” one was the 1973 model that still had the front drum brake.
Your best bet is the Vape CDI ignition. Everyone who's anyone with an RD runs these ignitions. Set it, forget it, and enjoy a real stator ignition.
Do they work on the 200s as well?
I’m not too sure if the rd200s have the same cam style ignition but I believe if it does Yambits website would have it listed as an option. ✌️
Using on RD 350 going well
Run the Vape on my '75 RD350B and '77 RD400. Best decision I ever made. Strong spark at the right time, every time across the entire RPM curve. Starts easier, more power, better combustion, less smoke. No longer have to rely on 40+ year old stock ignitions to get me home. For the everyday rider like me it's awesome.
Those RD's were strong running bikes. I never had one but always wanted one.
I've taken it on a few rides now love the sound and it's a quick bike, definitely surprised me! Crazy fun & it's been turning heads everywhere lol.
I had 2 or 3 of these back in the early 1980s. They were quick but a death trap. It was common for them to suddenly seize up at speed.
@@felixalbionNice! I hadn't heard about problems with them seizing, appreciate the input! Have heard quite a few stories about them having speed wobble issues though.
Nice bikes!
The YDS7 seems to have YR5 barrels on it . Have you measured the bore ? 350cc barrels generally have two extra wider cooling fins at the top of the barrels.
Funny I was just talking about 350 barrels for it yesterday! I haven't had time to look into the YDS7 much yet but actually just got back to working on it. Will definitely look into that, Appreciate the info!
I worked at a high volume Yamaha dealer in the 70s and got to pre-delivery service a lot of RD350s and 250s Every once in awhile I’d service and test ride a 250 that was just as fast as a 350 on my short test ride. Maybe one in 10 or so would just feel really crisp, responsive and a better ride than a 350. I never figured out a reason but it might have been a combination of cylinder sleeve alignment and piston clearance or who knows but those 250s were nice. Too bad we didn’t get the later 1976 through 79 250s that Europe and Canada got with the later style cylinders, electronic ignition and RD400 chassis improvements.
That’s awesome! I can’t imagine what it would’ve been like working at a moto dealership in the 70s, I’m sure it was like a little slice of heaven most days for a two stroke enthusiast lol.
@@WreckedRevivalIt was fun and a lot of work as some days we would sell 15 or more bikes a day in the early 70s. Lots of crash damage work to go along with regular service too but I think it was a golden age of motorcycling in the US. I bought a DS7 second hand, modified it and went racing in WERA with some success so that bike has a sweet spot in my heart. 🏁
Had a RZ 250 ypvs in the 80s...they should release that 2 stroke scent as a cologne...odour de Grand Prix!...
Nice! Would love to get a liquid cooled RZ250 or 350 one day, imagine they are pretty dreamy for a 2 stroke enthusiast lol!
In the final process of rebuilding a 72' R5 with new top end Wiseco set, 1st overbore, carb overhaul. tires/tubes, lights, points/condensers, chain/sprockets, seat, battery..was in pretty good condition otherwise with 9,097 miles
Nice! Our rd250 was definitely the easiest one to get roadworthy & it’s still going strong. Happy to hear another Yamaha two cycle twin will be back on the road!
@@WreckedRevival update, got it running nice,,,,but......no 2nd gear, had to remove engine and split cases, bad shift fork, two worn gears....put it all back together again, but now shifts great!
@@richarddegen6184 good to hear! Not so much about the shift fork and gears but cool that it’s running and back on road again now. Congrats on reviving a fun bike to rip around town on, sure it’ll be turning some heads!
also replaced 2 bearings in trans and all seals, crank and gearbox
@@richarddegen6184 nice! Just got the rd350 crank rebuilt with tz350 rods new bearings and it’ll be getting all new seals and everything as well. 🤘
impressive bikes, Where does the exhaust of the 350 comes from ?
We aren't too sure & actually curious ourself. Looks similar to DG expansions chambers that someone changed the silencer/stinger on
@@WreckedRevival thanks for your quick response. Once I´ve asked JL ( Jim Lomas ) if their pipes fixe on the RD250 too ( respectively are too big because made for the RD 350 ), but still waiting for response. Yamaha once made special exhausts for their TD 250 Racing machine, but they are not anymore available.
Hey wrecked did you end up using those orange dog ears ? I need a set if you are not using and want to get rid of them. I have couple of parts not using
No I didn’t use them, they’re in a box of my spare RD parts. They aren’t perfect, is some small rust/pitting but I’d be willing to get rid of them. I’ve got an email in my about me section if you want to send me a message there.
