Well done, a massive achievement, i must say when i saw your crankcase casting i thought the foot type mount was an odd choice for a motorcycle engine but now it makes sense, Your video making is quite impressive as well
This is absolutely awesome! I’m not interested in the machining, as I’m a carpenter, but I love mini bikes! I’m building my seventh right now. (I got me some kids…🤪) I would straight choke a man to get one of those engines to Michigan! It’s amazing to me the knowledge it takes to create an engine from scratch. And you wield it like a seasoned professional! New Sub!👍🏻
Now if you could cast a mirrored head. Allowing the use of a single carburetor , and the exhaust to rear exit on the rear cylinder. This is awesome! Imagine a short block, with the ability to use two Suzuki DR 650 cylinders! A roughly 1300 cc engine. Anything from 900cc to 1400cc-1500 cc😮. In theory, I'm thinking around 1200 would be better, 1180's-1190's cc displacement. Making power a bit higher in the rev range. Make it a bit safer on a mini bike.. a slightly lower bottom end tq! Maybe make replica air craft cylinders at or greater than 2000cc per cylinder, with a 5"-6" bore, like the liberty engine maybe make it a bit more modern shorter stroke , lighter piston. 4340 rods and crank. Cast a light weight piston using old pistons add some more silicon, make a good hypereutectic piston alloy. HD and long rods , get a roughly 8:1 compression, a 4"stroke with a 6" bore, use two 1.95"- 2.0" exhaust valves, two 2.100" intake valve use a custom cam grind made from tool steel with adjustable followers around .600" lift 280° 235-240 @ .050" with 300° on the exhaust use two 38mm carbs, on a plenum that bolts between cylinders. Using safety wire. Use one for idle the second opens at 1/4 throttle. With the pistons having a large dish hemisphere shaped directly under the sparkplug with smooth grooves around the edges to allow the air/fuel to swirl when the piston is reaching tdc. Use bevel gears to drive the cams. Off a 20 tooth sprocket driving a 40 tooth sprocket on a shaft with bevel gears and a oil pump driven from the far end. And a "distributor" on the near end. Actually a dual cdi looking like a distributor. A rotor with two metal bits for the pickups to read, one pickup mounted 1/2" higher than the other so the get their own separate ignition times. Looking like a old style magneto or distributor. With the cdi output going through beaded conduit, to the cylinder tops with a motorcycle coil mounted on the spark plugs the cam covers having fins to appear as a sleeve valve engine. Then scale this down with a 4"bore and 4" stroke for a mini bike , or even a smaller 3.25" bore and 3" stroke using two valves, 1.5" 1.25" intake /exhaust. A 30 mm carburator, have a mini block, small block normal block, then the big block! Sell them as kits finished castings that can require final machine work. If I had a shop with equipment I'd make one hopefully sell them! Definitely build one! ✌️ Awesome work
Other than the fact it makes it unique and my own engine. It would mean a new 3 piece crank which needs machining, hardening and grinding. . . Not to mention the Honda rods are far too short for the narrow V angle.
Thanks for taking an interest. The are more considerations to take into account than are apparent when you view this from the perspective of comparing what I am doing to Le Dan. That would need to be the subject of an entire video on its own. I think there is a difference between making a one off for a video and making something that can be sold and will run reliably.
Check out the video on how I cast the engine. If the pattern is smooth the casting will come out fairly smooth. You can sand and media blast them for an ever smoother surface.
Amazing. Saw the startup on Instagram and my jaw actually dropped haha. Stunning work, it sounds great
Thanks. The fact it sounded so good was icing on the cake.
Well done Jonny. Again, I'm impressed. I'll be in touch soon for a catch-up. Andy
Thanks Andy, sounds good.
That is so cool! I need!

I dig all the random highlighted projects you stage your monologues on…
Awesome watch. Even more satisfying to learn the process after seeing the comments in Tim's videos saying it's AI or fake sound. 😂
Thank you. When I saw those comments I had a little laugh myself.
Great work! The engine looks awesome!
I love everything about this!! Amazing Craftsmanship!
Wow, you're the man! Will these be for sale so we can put them in our own projects?!

New Sub!👍🏻
Thank you
Been watching you a while now, Fantastic to here you're from Palmy. Im just outta town, towards Newbury. Small world man
That's a mini bike you would ride, not just a lawnmower engine with two wheels.
Master!

My question is why use a linked rod and not two separate rods, wouldn’t it be cheaper to use the rods from the single cylinders?

@@OddsandEndsMachining im pretty sure these are the motors le dan likes to use ... in that case you can press the crank apart and combine 2.

easier to make the rods proprietary and use a common gx200 crank
how to make smooth surface on casting

Nice series IIA 109. What year is it?
1967, it’s almost ready for a WOF, it has a Holden 202 swapped into it.
@OddsandEndsMachining WOF? Not familiar.
I want one, how much lol
You’ll have to flick Tim a message as I am not going to be personally selling this particular motor.
It sounds more like bubbleboat bubbleboat than potato potato
