Yamaha Parallel Twin?

Maybe out-of-remit, since although it was definately a motorcycle engine. it wasn't actually IN a car or motorcycle (or jetski), but in a scrapyard.

Mildly idly curious, since I can't remember seeing a Yam parallel twin here? Looked quite big so I guess could have been from an (illegally imported?) TX650/750

It's a Yamaha 2-stroke twin with reed valve induction which makes it from the Rd series. Judging from the shape of the cooling fins I'd say it was a 250, 350 or 400cc model, but they all look so similar it would take a close up of the cylinder base flange to identify it further. From the looks of it I'd guess it might be useful as an anchor for a small boat.

Prolly a 250. So many more of them than the larger ones. I used to have a 250 with 350 barrels. Chewed oil, smoked a lot when cold, but popped wheelies off the lights very easily unless you slipped the clutch a lot. Bags of fun and taught me to handle bikes that did not want to go where you pointed them (frame like a wet noodle).

Too many people! Almost all of the world's problems are due to overpopulation. The rest are due to religion.

Sandblast it down, powder coat it and sell it as a door-stop or a window display.

Wasn't planning on doing anything with it, its probably irreperable anyway (and its the wrong shape for a boat anchor). I just wondered what it was.

Surprised its a 2-stroke though, especially if it could be a 400.

Given the number of times people on here have lamented the abscence of big 2-strokes I'd have expected to hear more about these if they were around in any quantity, so I guess they aint.

Wonder if it would fit in any generally available frames. SR150?

They were standard issue when I was a teenager. Great, great bikes. EVERYONE and his uncle got a used RD250 as their first bike, sold it on after a few months and got an RD400. Fucking fast! There was also the track version that I raced for a few years that was a 350 and much faster than the 400. Glory days!

I'd read of the RD350 (often described as a "giant killer in its day") but I probably wouldn't have noticed one before coming here.

The existence of the engine might suggest there might be one or two intact bikes around, but I don't think I've seen one.

According to Wikipedia an RD350B was made in India until about 1990, and there is still a spares supply chain operational there.

It was indeed a giant-killer in it's day. The existence or not of a complete bike is pretty irrelevant since the chances of one having a legal registration are basically zero.
