I had my 1970 Norton 750 engine rebuilt MAINLY because it leaked oil from the case halves after 45 years. After spending $1700 CDN to rebuild the engine ( a 2 cylinder only ! ! ! ) completely right down to main bearings, it does NOT leak from the case halves any more, however, I had to completely remove the top end again and replace the rings as the mechanic broke the oil scraper spring tip off during his repair job rendering the oil scraper useless. It burned so much oil I could not see. The base gasket was also so damaged that the oil poured out of the front of the engine. The combustion chamber on one side had aluminum chips inside and one was stuck to the valve seat causing it to backfire. This mechanic was recommended as being good at rebuilding vintage British bikes by a vintage parts supplier. Just be very careful. Watch out for the dirt floor and the chipmunks running around on the workbench. Never liked poetry very much either. He's much better at that than rebuilding vintage bikes. :-O.
Wow! shows its possible! I plugged a leak around a head bolt ( yes i know it shouldnt leak there ) only for the one on the other side to start leaking, telling me its a lot to do with oil pressure. 😯
Oil drips from British bikes can be fixed,but not without completely dismantling the engine and chamfering the relevant holes (the ones around the oil) also,gasket sealer may be used.
British bikes leak oil because the crankcase bolt holes need chamfering,because,metal is pulled up into the gasket when bolts are tightened, causing leaks,not particularly easy to fix,but if you can dismantle a engine succesfully,it can be done,of course you must put the engine back in running condition.
Interesting about the bolts pulling the surrounding metal up into the gaskets. Never heard that. Makes sense. What was your source for that info? I guess everywhere there is oil, chamfer the bolt holes?
Why do british bikrs leak oil? The gasket between the two crankcase halves gets ruptured by the metal rising from the female side of the crankcase which can be cured by chamfering to prrvent this condition.
Very nice, reminds me of a 64 I had, very much the same. I loved that bike, never should've sold it. Thanks for sharing this, a pleasure to watch.
That sound brings back good memories, an honest Triumph.
Memories for me too. I had a 350cc back in the sixties. Now got a Speed Triple.
My dad had one of those in the early 60s and there's a picture of a 4 year old me sitting on it.
Lovely example. Nothing better in the shed than a sorted 1960s or 1970s triumph twin for the occasional short spin.
Very nice to see. Always good luck on it.
A Triumph in it's natural habitat.

Triumphs benefit from valve guide removal and replacement,particularly the exhaust valve guides; )
I noticed you didn't tickle the carbs. She must have already been warm, right?
Nacelle in 66?
Mine never leaked oil.however my cb550 does

It's battered up a bit but she's still a beauty.
That grin says it all!
Is it for sale
The cool thing about motorcycles is you can ride them on highways,and cross country.
Any way youre selling this?

Don't smoke the tires on a rare classic,just ride it sensibly.
👍
excellent 👍👍👍👌👌🙏
Where are the pillion footpegs?

There is no gasket between the crankcase halves, there is on the chain case though.

There has never been a gasket between the crankcase halves on my T120r. Never seen a gasket on that joint
Motorcycles were really popular back in the day,Nothing to riding them.
Better than a moped!
What a classic!
If it's for sale, hit me up please
The video is four years old
A triumph on English roads,nice.
What a stupid admission of slack assembly; "It does drip a bit of oil like they all do".
Brit bikes have a rep among bikers as being temperamental and leaking oil, so there you go(.
Brain bucket must be mandatory im ol' blighty m
Rare to see a sixties triumph in action, very close to the way it left the factory.
This was filmed in 1983?
Oil leak easy to fix, if you can disassemble a triumph engine and rebuild it to running condition.
Get proper gear. You should know better.....
Wot?! No wheelies? Why are the British so bloody skittish. I'd be laying that tyre down with smoke. Cheers!
