Thanks for showing me what my Dad was doing to his Panther in the kitchen when I was a little lad in the '50's. He's been gone almost 35 yrs. now and just watching your demonstration has brought him back to me a little bit. 👍👍👍
Back in 1979 I imported to the USA a M120 with Busmar DA chair. It was well used to say the least !! I had to rebuild the bottom end and fit a new piston. Luckily a spare bottom end was included with the bike. As I worked in auto parts spares trade I was able to find a suitable automotive piston to use from a Toyota 18RC engine as I recall. The only mod I needed to make was open the piston bin bore in the piston a few thou. Ran it for several years here in the Arizona desert heat in the summer 40-45 C temperatures are normal in the summer. And remember I was pulling that big DA chair along also. Got a lot of strange looks with the left-hand mounted chair !!! I adapted more than one car engine part to a bike .
For some reason I started to watch this and I was hooked. What a life enhancing pleasure. I drove Japanese infallibles but this is eye opening. Can't wait for part two. Thank you.
Thank for the video. I’m a POC member with 2 Panthers from Australia. I’m currently making a 1916 Thor engine from scratch. Looking forward to more videos.
Excellent video. I restored a 1950 model 100 in 1982. It was being judged by Phil Irving at a show in 1984. He quietly advised me to block off one of the exhaust ports with a brass bung, suggesting it would add to performance. He was quite right. Phil was a genius engineer and admired the Panther design.
An interesting story Christopher. I too am a fan of Irving, with several of his works in my collection. He has the knack of explaining complex principles in simple terms. It's pretty clear that the big Panther's twin-port head was about appearance, not performance. P&M did produce single port heads but they are few and far between.
Thanks I have been building Japanese engines for years I am about to rebuild a panther 100 it was very helpful to watch a rebuild before starting My bike was rebuilt in the 70s but never finished but was so badly done I have had to start from scratch (ring gap 178.th) Many thanks Dean
Thanks Dean. I have learnt so much from UA-cam posts and it's good to give a little back. With your general engine build experience I'm sure you'll have no trouble. Just remember, valve guides to worn-out clearances!
Excellent assembly class, I watched with great satisfaction. Well designed machine. Careful assembly. Moments when it looked like surgery, everything guarded against possible infections. It will work with great reliability. It will be a pleasure to see this motorcycle running. Congratulations St. Jones!
@@PantherOwnersClub1 I had known Panther's story for a long time. I had a mechanic and electrician friend, who passed away, who had a 250cc with air injection in the front telescopes. However, I was unaware of any more technical details of the interior of the machine. I was surprised by the projects and how much this bike is able to withstand long trajectories without frequent stops. I really admire the spirit of tradition of the English people as a whole. It is a good thing that they left this globalist European bloc. In the beginning it will be difficult due to rising living costs. However, England will adapt quickly to the new state of freedom. I was unable to discover the functioning of the oil pump in its entirety. Genius idea. I wish you a 2021 full of good projects at this level. I really enjoyed the two-stroke. Brave in acceleration. Reminds me of the no less famous and classic James. Very nice place or your home. Follow a useful link, if necessary: www.brufnut.de/WORKSHOP/LUCAS/lucas.htm
Enjoyable and instructive, with a few new tips to me - Thanks. But I don't understand, "We encourage it to move at this stage" ? Where can I get the book, "Motor Cycles and how to damage them" ? (sorry - old joke)
Thanks 99nadroj. That comment referred to the crankpin moving in the flywheel. You can pull up the nut to its final torque before truing but I find the mallet force then required harder to control. Try both methods, see which suits you. I picked up pre-war 26th and post-war 33rd editions of the book which taught many of us the proper way to attack a motorcycle so I'd be surprised not to find something with a Google of the title.
Imagine that engine with an aluminium barrel and head with 4 valves to give it a bit more pep - say 36 hp at 5,000 rev/min - still lazy but more able to sustain 70mph with top 85+ What do you think?

Was thinking about a book I saw *many* years ago, entitled, “the book of the Panther” - and then he pulls out a copy of that book!

I’ve always wanted a Panther...although I live in Bradford near to where they were built I rarely see one on the road
Thank you very much for that, educational and entertaining in equal measure.
Thanks, enjoyed that. Always wanted a heavyweight. I am on the hunt for one soon as lockdown allows!

crank fitting is a very skillful work
I could watch this for hours. Better than a film.
Had a 1955 M100 bobber, loved it, lovely therapeutic video.
excellent build JJ..I know who to come to now

Glad you enjoyed it. Always a risk to put ones head far above the parapet when there are so many accomplished engine builders out there:-}

Nice work.
Great film, very good narration.
Fantastic gem of a video, many thanks
Well done JJ, nice one!
And thank you Laurie for the collected knowledge in your excellent book; a life-saver for Panther builders.
Great video very different than the harley engines i have built but the crank truing is the same!
Them webs must be about the heaviest in a motorcycle,
Another excellent video. How do you clean your cases?
Its a long time since i seen one o those torque wrenches 😂🤣👍
Get UA-cam to show you the panther 1300😁
Did I detect a PO No1 screwdriver in use?
Spot on Gordon. I am delighted to award you this weeks 'Tool Nerd' prize!
@@PantherOwnersClub1 I still have a good selection of mine from 40 odd years back.
