Wonderful to see "Alan Millard" has inspired someone to take up the craft. but you must have missed the part where AM puts all the parts in his BBQ to preheat the castings looking forward to seeing the project progress Right on Man
The Rd 350 was a technically advanced motorcycle at that time. It stood out above all it,s competitors. The Kawasaki 3 cylinder always had problems with the cooling of the middle cylinder. It is a good idea to remove cooling ribs 2,3 and 4 from the cylinder and weld the circumference closed and use it for water cooling. It,s conne be 500cc pure Wow-ness and of the charts sound. Can,t wait for the next video.
I see what you were doing. My question is ,why didn't you just put the two halves together. You could have had a four cylinder insano machine, with so much less work. Of course, then the frame would have had to have been hacked all to pieces to fit it in. Still this is incredible work. There is a British guy who does this kind of motorcycle Dr. Frankenstein work. Like you, his bikes are just incredible works of art. This should be really fun to watch. I look forward to the next videos. I just watched a video on RU-vid of two motorcycle guys talking about the Yamaha TZ750 two stroke race bike. In that comments section there was a guy who actually raced the TZ750 two stroke race bike. He said the most dangerous time for those bikes was coming out of high revs on a track like Daytona and closing the throttle all the way. This is because at high revs, when you drop off the throttle, you close the air and fuel coming out the carbs. Well there is oil in that gas that lubricated the engine too. He said he blew an engine and woke up in the hospital two days later. The accident ended his motorcycle racing career. He had had a great career too, judging by his accomplishments he listed. I don't expect you will ever be doing full speed, sixth gear, divebombing runs on this bike, but I am passing on that information to anyone with a street two stroke legacy bike now. Especially those two strokes without a two stroke oil tank and pump like Suzuki had. That was a fun comment section to read. Alot of love for the triple cylinder two stroke Yamaha. Great luck with the build. Subscribed.
Nicely done so far, though in hindsight, I would've kept the outside left gearbox casing (milled/skimmed in lpaces on its inner face, to reduce road crud catching,( to act as an outrigger support for an extended gearbox output shaft & sprocket;.. ...since the motor as a whole isn't much wider, and the the over all looks and balance is kept fairly equal - plus having a long extension shart for the sprocket to be placed where needed, means the engine can be remounted central to the frame, and still allow spacing for the rear wheel and drive chain to be placed at an offset distance, without undue additional torque loadings upon an unsported stock output shaft would face with an adhoc offset sprocket.

This reminded me that 3 cylinder racing Yamaha's were first created in the the 70's, Ted Broad the English tuner and sponsor was probably the first to do so in 1972 and later on around 1976 by Ferry Bower a Dutch tuner that had a close relationship with Yamaha, there is also a present day guy who built a 4 cylinder engine : ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-UONSUq2faRA.html Needless to say I admire your project well done.
I'm not sure what amazes me more 🤔 Building a 3 Cylinder Engine or someone who can use a Hacksaw 😅 A great project to build when you have time to think about what your doing. And of course enough time to cut anything with a Hacksaw 👍👍
Excellent work mate, will definitely be looking forward to seeing more of this build.I am also on the journey of making a Kawasaki 4 cylinder from two H1 500 engines here in Australia . Were are you?
This is fabulous work. Engineering skills to look up to. But I thought that two new bikes could have come into being rather than sacrificing one engine for one cylinder and the leftovers are for the scrap bin.
