That new Vtwin Harley is exquisite, but I've bought a lot lately and as they say Now for Something Completely Different. Getting an engine tomorrow, single cylinder, but BIG (quarter ton) and OLD (near 100 yrs) it will be fun.

That might be stretching it, but i love your enthusiasm!

Glad you enjoyed it. Welcome to the comments section - I like the sound of vacuum engines vs closed-system, stirling hot air engines

Hey Engineman! Keep making vids. ...I was running my H75 today, it always starts and is always satisfying! Yeah the vtwins are a special lineup. Also Microcosm (Becoming OKM ?) srating to paint some models is a great move I think. Keep in touch man

@ThomasPCGuruENGINES Hey Thomas , thanks for your support! Their engines are brilliant . Yeah, a rebranding is on its way for their independent shop. Lots of awesome engines are on the horizon from them 😎👌

"Glow" engines are now called "nitro" engines as the fuel has added nitro for bang. On my channel is my 60-year old "diesel" aircraft engine running. God I loved that as a kid...

@@ThomasPCGuruENGINES my brother and i had motors sizes of .010, .020, .049 and a really big one that i think was .35 i think. we flew control line planes and free flight planes but as kids we could not afford r/c type planes and back in the early 60's were not very numerous with kids more like adults had them.

I have never heard anyone got the R90S to run decently, just frustration, so good on you. Is "Fuelite" lighter fluid too?? I had some "fuelite" from Bunnings which the engines ran happily on but gave it up because I read the octane is lower than petrol and this was when I only had hit-n-miss engines; I wanted biggest hit. (sidebar - It evaporates REALLY quickly. Perfect for evaporative carb - eg used it for their 1896 Benz project locally.) I like an engine to go from "works ok" to "works perfect" rather than "pig" to "pig in lipstick" Cison v twin I'm looking at you here. That's probably a bit harsh, but I'm a bit over it...

@@ThomasPCGuruENGINES I think they are the same thing, zippo and likes of it work really good on R90s. It's been so frustrating to say the least. But I think I made it to run as close as to the real engine after it's warmed up. Had to make major mods to get it work like that. I think the high octane fuel is useful when the intake crossing hot surfaces, or the cylinders have very high compression. As each engine they make is different in design, assembly and quality, it is matter of trial for fuel.

Yep that's the prototype for this model. I'd love to have a 50-100cc vtwin powered minibike for fun in the park...that might happen in the next year. Chinese manufacturers are just realising how much us westerners love 45 degree v twin 4 strokes, hopefully one of the many minibike engine manufacturers will create a small v twin for us, eh? Actual Harley is a bit out of my price range and I'm an absolute beginner, probably safer hooning in my MX5

Right on! You bet Dave :)

The ignition in these sparks both cylinders at the same time, but only one is compressed and fuelled. Then the other. Take a plug out or both and test it for spark a you turn the flywheel. there arent timing marks that ive found, use a toothpick in the sparkplug hole to feel tdc

Great point! "Oil leak...very realistic" ha ha yeah...

Yep and these V twins are not simple to take apart and reassemble with your own gaskets...

@@ThomasPCGuruENGINES Don't need to replace the gaskets. The engine leaks are apart of the experience

Short and clear comment...and I agree.

Context???

Maybe, I'm having a hard time getting them running well

I'd agree...I've never measured it properly in practise though...

The Cison???
