This takes me back to my youth, not only did I keep my own pommy bike running like it should but many friends bikes, these BSA, TRIUMPH & NORTON motorcycles were a bike part of my life..
I love unit construction Triumph's and BSA's, been working on both since the early 70's. At the moment I have an A65 Lightning, with a 750cc conversion, and a T140v . I have built both from basket cases and have made a lot of special tools to do the jobs.
These English motorcycles were a gift to humanity, fun to ride there low down grunt, they went in to corners by just thinking about it, I would spend hours getting them to run right, it became an obsession, The Commando was my favourite(750) the best wheel stand motorcycle, the BSA lighting was also beautiful, my friends used to say to me, how come you get the good bikes, I would say I make them good, in the end I got sick of working on friends bikes, The electrics of these 60s Pommy bikes were shit, regulator was a zenor diode a simple four diode for AC to DC but it kind of worked, Thanks for the memories..
Hi I will be doing a top end rebuild very soon and getting mine rebored I'll be using Hastings pistons and rings now my question is when I do assemble should I do dry assembly or should I lubricate the rings and bores I'm not sure as iv hear using oil can glaze the rings and they will never seal then what's your thoughts Cheers
Here is a tip for all of you, after a rebuild or long hibernation. After firing up the bike place your finger over the oil return. If you have a clear plastic hose feeding the rocker you will see the oil shooting up to the head. Going to where it is needed sooner than later. 😀 Happy engine.
Great video, I'm going to be restoring my '67 T120 Bonneville. It was handed down to me through my family. I've determined that it has a seized piston. Any advice? Where do you order your parts from?
Una ves busque para una 350, como es el funcionamiento del tiempo en los piñones de distribucion, y encontré que las marcas de sincronía de tiempo solo vuelven a alinear a las 95 vueltas, esa moto no pudimos encenderla por qué en algún taller le modificaron piezas al no ver qué esos piñones no alieneaban como en otras motos. Es cierto esto?
I'm doing a top end on my 71' triumph and noticed it still had an oil leak, I believe it's coming from the split case. Do you have videos on how to seal it? Engine looks complicated for me. is there an easy way to seal it
I still just quite understand why the Triumph engine designers decided to make the engine with a 360 degree crankshaft configuration. That is a lot of mass going up and down, speeding up to TDC, stopping and going to BDC. It may as well be classified as a "Thumper', but despite this I think it is one of the greatest motorcycles ever produced!
I set my ring end gap @ 0.001 tighter than mfg specs. When the idle got slightly rough, I shut it down till completly cool. Then repeated many times. This is not reccomended for beginners in mechanics. It takes a special FEEL.
Im looking for a build on one of these motors, my dad has one in a chopper that hasn't been run in awhile and I want to get it going again. Is it something a person with decent mechanical skill can do? If not average cost for someone to go through the motor back and running.
I would love to use ring compressors, but, since I make my living fixing these things.......I learn to make do. I once had to do rings on a Honda CBX....once.
