I have seen that also. Nice catch!

@@fjdelmonteThe original pipes with the bends when hooked up to the rubber oil hoses made it difficult to have access to the bolt which had to be loosened in order to adjust the primary chain tension.

T-Fitting and vent tubes are stock original parts.

@@fjdelmonte That didn’t answer my question.

1970 Triumphs were "small frame" bikes with separate oil tanks on the right side. 1971 and later Triumphs were (are) large frame bikes with the frame being the oil tank. If your bike has the oil in the frame (OIF) it should have the T-Fitting and the vent lines shown in the video. If it is an OIF bike and does not have the T-Fitting someone has removed it in the past. If it is a small frame bike with a separate oil tank it is a 1970 bike titled as a 1971. F.

Same thing here but you have to be a "real" business to qualify. Home based business, nope.

@@fjdelmonte I'm shocked. I'm a mobile grease monkey working from home. I could apply for and get a UK one. Road testing etc. Different countries and all that. I automatically assumed the USA made stuff easy for entrepreneurs.😞

Yeah, so true. I'm only putting all this time and effort in because I'm totally booooored. It's all uncharged. No cost to the owners. Things will pick up when it gets cooler and everyone will suddenly pull stored bikes out and want to go riding.

@@fjdelmonte I live in Florida where it's hot all year round except for a little bit in the winter in the mornings. I love riding so much it is so much a part of what I am. I have had my Sportster for 25 years now and I have had my Triumph TR6 for 40 years now. I can't imagine selling any of my motorcycles.

Florida hot? Yesterday it was 114 degrees here. Standing outside for just a few minutes the sun actually, physically hurts your skin. If you ride a bike the wind does not cool you down at all. It's like waving your hand around in a hot oven. On the other hand we had a pool party last Christmas day, so there are compensations. Come for a visit next July. I will rent a bike for you. My treat. BTW: My brother lived in Florida until one of your famous four-engine mosquitoes lifted him up and flew away. Haven't seen him since. Sometimes I miss him.

@@fjdelmonte Don't tempt me . I might take you up on your offer. I experienced your kind of heat in the 1980's on my trip act the USA after the Air Force. How it could be so hot during the day and so cold at night l don't understand.

Sparta.

We did a test ride on 6-21-24 and a couple of other rides while looking for oil drips. czcams.com/video/0dwtOhSBY-4/video.html 06-21-24 - 71 Norton - Green FB - Test Ride Success

I agree It's not just the rings The camshaft gets a really hard time under 2000rpm during break in The very last thing you want to do with a commando is let it idle Especially after a rebuild

Darn! I forgot the silent prayer! Thanks.

Yup.

Hi Rob, thanks for watching and thanks for commenting every now and then. Actually, no, I don't charge storage. Usually the client has a pretty good reason for not being able to pick up their bike, so if I have room available I just tell them leave it. But in the fall, winter, spring, when I get overwhelmed with folks wanting to get their bikes into the shop I will "press" a little bit anyone whose bike has been here too long. I'm retired, and run a home based, informal shop, and so I'm pretty easy going with picking up bikes and stuff. If I were a real business, or if leftover bikes were impacting my space, I just might be a bit more strict. Ride On! F.

I think, if I were to be working on a swing arm I would look into the Baxter Cycles www.baxtercycle.com/product/bcr-01-swing-arm-conversion-kit/ or British Cycle Repair at: www.britishcyclerepair.com/rocker-spindle-oil-seal-upgrade

Wipe it off every time you ride.

Yeah, I agree that is a good way to check for proper orientation of the rocker flat. But . . . I (we) had just put the valves and rockers in a few days prior (see the video) and I was pretty sure the flats were forward. Soooo, we pressurized the rockers and got good oil flow out of both ends of the rockers and decided it was OK. The general consensus is that my machinist's client expected to see a lot more oil when he did the same test. Thank you for watching and writing. F.

Hi, I LOVE your plan! It is a great idea for a privately owned bike and I applaud your ability to do the work you describe. (I am completely serious.) But, it would be a radical case of overkill on a client bike. Remember, it took 50 years of riding, and probably a hard fall over to get the side stand screwed up to the point it needed the adapter, and the repair made will give the bike another 50 years as is. But thank you for watching and taking the time to write. Ride On! F.

Thanks. I knew I had seen the filler cap up at the top of the frame neck I just couldn't remember where/what/when. F.

Parts Book 1973 doesn't show the tubes. Parts book 1976, '77 does show them. I don't have Parts books '74, 75. But my '74 Norton came with the same style downward facing intake tubes in the air cleaner and I was told they were "sound suppressing" devices that pointed the "intake noise" down to the ground in order to comply with U.S. sound reducing laws. I expect the tubes in the Triumphs were for the same reason. We always removed the tubes (Triumph and Nortons) as we thought they restricted the intake air flow. They probably didn't, at least not enough to make a noticeable difference, but we were really cool back then and believed everything each other said. Thanks for watching and for writing. F.

Oooops. Clarification. The bikes mufflers are not pea-shooters, but they are not the stockers for this (1972) model. They are stock style as used in earlier Triumph models. Great sound tho!

No. Just stock Triumph mufflers. Search thru the published videos and look for some of the 1971 Green Goddess vids. It has pea shooters. czcams.com/video/-gpBzpNuPp0/video.html 07-12-24 - Oil Leak Checks czcams.com/video/-gpBzpNuPp0/video.html 07-12-24 - Oil Leak Checks czcams.com/video/oLbG-lpMv1A/video.html 07-07-24 - 71 Norton - Green FB - Oil Leak Check czcams.com/video/LUzUO9frfJo/video.html 07-05-24 - 71 Norton - Green FB - Sump Vent Extension

6:48 the small pipe is to vent the oil tank vapour down to the branch fitting, otherwise the oil tank/tube could get pressurised (or is unvented)

​@@fjdelmonteStock mufflers, albeit from earlier in Triumphs production years as a 72 Bonnie should have reversed cone type mufflers.

Yes, correct. Earlier model stockers. The 72 had tapered mufflers and a cross-over tube between the pipes. Thanks.

Hi Frank, I did some research and found the source of my confusion. Apparently lots of people are calling the original "sausage on a stick" mufflers pea shooters. When you see real pea shooters (green goddess) you can see the name fits. Looks like pea shooters are a Norton muffler. Emgo makes them to fit Triumphs.

Wow! I never noticed but the Haynes manual is speaking in British measurements, which means that 5/8ths of a pint should be 12 ounces rather than the 10 ounces I computed. I think. But the British ounce is smaller than the U.S. ounce. So, I just dunno. (Now a days, numbers make my brain hurt.) Anyway, the oil that came out of the primary on this '72 Triumph measured 18 U.S. ounces. It seems like a lot. Thanks for watching and thanks for writing. Now go out and treat yourself to a 16 oz steak dinner. U.S. or British.

I didn’t think there was any significant difference between UK & US fl oz, just a UK pint has 20 of them and a US pint has only 16.

Hmmm. I went thru the parts books from 1966 to 1976. 1966, 67 - No Level Plug. 1968 Thru 1973 - Level Plug. <==== Includes this 1972 1974 - No Level Plug. 1975 - No Level Plug? (Don't have Parts Book for 1975) 1976 - No Level Plug. So, I THINK the 1972 bikes had a Level Plug just because they were still using the leftover (with Level Plug style) primary covers. BSA's and Nortons wet sump because they have rotary oil pumps. BSA's have a ball valve that "usually" stops the oil from leaking down. 1975 Nortons also have a ball valve. Older Nortons can be modified (AMR) to install a ball valve. Triumphs have a twin pump style oil pump with ball valves built in so they don't wet sump. (In my experience). It gets complicated, doesn't it! Thank you for watching and writing. Ride Safe! F.

Ooops! I kept saying "Drain Screw" when I meant "Level Plug." Sorry.

Oooops again. I fixed it.

@@fjdelmonte my T120s & T140s have all wet-sumped despite the twin tube oil pumps and despite tapping (reseating) the ball bearings down. I’ve had 5 of them so I know from smokey, oily experience. I’ve torn down and rebuilt several Triumph twins over 40 years and that still e…… it’s a mystery. Maybe debris gets under the return side ball. My present T140 is a ‘73 build (during the lock-in) according to the engine number registered and sold ‘74 and it has no plug - I’ve just been out to check! I have an external spin-on oil filter on the return side before the oil in-frame tube so hopefully the oil will be cleaner in the reservoir and into the pump.

Thanks. I didn't know Triumphs could wet sump.

Which problem does it not have? A difficult to find oil leak, or the high oil level in the primary case? I'm still puzzled by the 18 ounces of oil in the primary. Can't figure out why that was a good design idea to someone.

It could be original. I don't know. If I have a bike that doesn't charge very well I test the rotor by hanging it from a big box end wrench. If it hangs well and can't be shaken off easily I figure it is still good. That's not very scientific but it's one way to do a quick check. I have seen rotors that would barely support their own weight. Changed them out right away. Thanks for watching.

The breather hose is actually two pieces with a "splice" in the middle. Good idea to check it. I will take a look today. Thanks.

I will continue the search. Next test will be after Kevin returns and does an extended test ride. Then we will let it sit on the sidestand and see what develops. At this point I THINK the big leaks (dinner plate size) the owner photographed were from the Primary Case Timing Access Cover due to the 18 ounces of oil in the primary case resting on the cover. Standby. Time will tell.

Pre units are obvs different but l sort of suspect something is amiss in that vicinity.

Both the Primary case seal and tranny mainshaft seals were replaced when we changed out the clutch assy and I can't find any evidence of oil on the backside of the primary case nor on the front of the tranny behind the sprocket. I will continue the search. Next test will be after Kevin returns and does an extended test ride. Then we will let it sit on the sidestand and see what develops. At this point I THINK the big leaks (dinner plate size) the owner photographed were from the Primary Case Timing Access Cover due to the 18 ounces of oil in the primary case resting on the cover.

@@fjdelmonte Thanks for the reply. I did think I had missed one.👍👍

Brilliant! I always wondered why they changed out that nice big rotor cover and put in that smaller timing hole! I think you are 100% correct.

😂😂😂😂😂👍​@@fjdelmonte

I am so thoroughly retired I also posted the same video twice. The only good thing about being old is being old.
