That Giant Piston would act like a Wacker Packer! The Vibration would be Crazy - Cool None the Less

[@jamzholm]

So exciting! It will be fun to see when all the little bugs get worked out, a permanent starter is figured out and the first road test ride!! Loving the videos, great job to all involved!!

[@chasebh89]

My dad used to say Harley's shook themselves apart. Glad to see someone given them some competition!

[@kathrynwhitby9799]

and the flames came out of the right port too! 😁

[@fukhue8226]

They have it jetted a little lean. It causes them to backfire through the carb. It really doesn't matter. This thing will vibrate so bad no one will ride it more than one time or one mile.

[@michaeleckhard763]

Yes Doubleport.

[@beaterbikechannel2538]

5 intake ports, two exhaust but the sleeve only has four cutouts. They line up in the correct way during the cycle it's fascinating how these Bristol engines worked.

[@johncrowley5612]

Tremors felt down here in Aus.! I note that the chain has already surrendered to the impending massive torque load. Congrats and well done.

[@northlandrider5396]

The sprocket bolts shot through in fear as well.

[@julianb.9805]

Absolutely magnificent! Ive been excited for this day to come and now im even more excited to see it running and hopefully going on the road sometime! Great work and enjoy ur drinks!

[@martinw7091]

Such a beautiful piece of engineering. Im here from Facebook! Saw a short of you starting the bike. Saw how simple yet complex your engine design was, and became instantly intrigued. Glad you finally have it started!

[@TheBas1984]

Niiiccee!!! Earth shattering machine!!! You can be really proud!!!!

Last week, me and a bloke put to together a Vulcan 400 with straight pipes.the noise in the shed when we started it was deafening. But now i saw this beast, id say it was rather quiet...😂😂😂 Great job there!

[@AmericanLocomotive1]

Congrats! Hopefully you'll be able to get the starter situation solved without resorting to dropping compression further. Also, I wonder if you need a stronger spring on the compression relief? It seems like it may have been getting sucked open a bit on the intake stroke whenever you closed the throttle.

[@davidaughinbaugh8643]

Well done lads!!!

[@davegibbs403]

Awesome! I just caught up on watching the whole series. When you said £300 for the aluminium to build the new head I nearly sh8t myself. I was shouting "Make one out of something cheap to check if the starter can beat the compression." Of course, you have done it now, but I have piece of nylon if you want it. About a foot across and eight inches thick. Fnaar fnaar. I drive all over the place, frequently near Derby, not a huge problem to get it nearer. (I can't fit in on my lathe and want it to go to a good home.) I will be watching future episodes, just say if you want it, I'm known as Grog.

[@philiphicks9656]

Some seventy years ago -late 1950's / early 1960's I was working in the ERD [ Engine Research Dept ] Patchway works of the then Bristol Aero Engines Limited. We used to run single cylinder sleve valve test engines. Hercules or Centaurus size pots, they ran as far as I can recall with a heavy flywheel. I think this motorcycle application may have had a crankcase etc from one of these units. A sleeve valve crank mechanism would have to be involved. I reckon it would jump up and down a bit without a well balanced crankshaft and maybe a flywheel as well. We ran many separate parts of the whole engines to research and hopefully improve each units performance both piston and jet engines. Piston engine research was just about finished when I was assigned to the ERD.

[@StoneEng]

@@philiphicks9656 interesting! This is our own design, but I'd like to see any old photos of the single cylinder test units. Especially any power graphs - I don't suppose you have any? Our flywheels are 50kg.

[@ephenj]

Forever and ever Even growing up when I was like 12 yrs old I would look for videos of one of these running. Absolutely awesome what you guys have done and it sounds amazing. The Napier sabre engine is artwork always found it amazing how much power it truly could make. Very very cool beyond cool. Subscribed it's so cool.

[@StoneEng]
