Yay! And all for less than 4 litres of “Motorcycle specific” (ripoff) oil!

Yes sirreebob!! A steal @ nz$50 total.

The guy a the counter stated Castrol was on special when I went to pay for the three pack. I replied "No thanks this is better!"

Goat the XF650 oil/filter change is due in around a 1000kms.

Darkys the CB555F oil/filter change is due in 1400kms. I changed the recommended 3000km oil change and 6000km oil/filter change to 4000kms oil/filter change a few decades ago with no problems at all since then. Usually have to do a few small top ups over that time which is no biggie. Darky is still on standard sized pistons after 164,000plus kms,is still starting first pop and running very well throughout the whole rev range.

I lock wired the choke lever permanently open non the CB because around town I was knocking it closed while wearing riding boots or gumboots.. Quite embarrassing when at stop lights and other intersections or going around a corner when she stalls.

terrys threads always go like this mate.

It's nice to have a thread without anyone getting hot under the collar.

Ha ha, well I started the thread to ask where I could get a 48 T sprocket for a CB500 Lester rear wheel and Wilbur posted a link on page 1, that proved perfect, I've ordered a custom sprocket and am just waiting for it to arrive.

Now that's out of the way, I don't really care where this thread goes, oil, handlebars, tyres (tires) ignitions, cams, you name it, we can chat about it. Have at it!

I wondered, momentarily why you'd be riding in gumboots, then I remembered that you're from NZ, so obviously they're the appropriate attire for taking your "wooly girls" for date nights on Darky.........

Originally 20w50 was in a blue 4ltr pack.When it changed to black it had me confused for a while.

When I'm riding Darky I carry a plastic quart container of oil in my shoulder bag along with chain lube in case I decide to go on an extended ride. Which happens quite a lot if I'm in the right mood no matter how bad the weather gets.

He He lol. I wore steel cap gumboots for riding for about 8 years or so until they started cracking. Can wear more socks during winter

Before that it was combat boots until I ruined all the rubber soles from being too close to m/c rally bonfires after consuming far too much Green Ginger Wine.

Ah the old Stones "Green Whinging Grime" was mandatory "Jack Rations" for old soldiers like me back in the 70's and 80's. I did a day navigation exercise in 1989 and was teamed up with an ex Commando Vietnam vet. We wandered around the bush aimlessly for several hours, when I realised I'd drunk all my water, so I asked him if he had any spare.

He passed me one of his water bottles and I took a big swig, and almost choked, it was GWG! I asked him if he had any water, and he gave me a steely look and said, "Never drink water mate, don't you know that fishes fcuk in it?" Well he had a good point, so we staggered off together and I finished the litre of GWG along the way. Great days.........

When I was posted at Hobsonville we had some US ground crew on P3 Orion exercises visit the junior ranks club. We introduced them to Purple Death. lol it was so funny. Because PB is sooo easy to drink they over did it and were in no fit state to work on the fight line the next day he he. Needless to say their unit commander wasn't very happy.

Well there you go mate, another parallel, I was on the ILS`team for Air7000 in 2015-2017 to replace the P3 with the new P8 "Poseidon".

I always remarked that the ILS project for the new aircraft was quite the "Adventure" but the RAAFies never got my joke, or perhaps didn't want to ask, in case I spent the rest of the day thrilling them them with witty anecdotes......

You're most likely a brother from another mother lol! Never really found out what Dad got up to in his younger days

I finished up in the RNZAF after being in for 23years. That was enough. When I got out I ddn't want to have anything to do with military related stuff. Cut off the umbilical cord completely so to speak, I'm glad I did. Military pension has kicked in and has helped out quite a lot. So life is quite relaxed now. No hurry to get anywhere fast....

***** † OIL † ******
What about cam wear with such new API spec oil as SL?
(Low level of phospherous.)

Crank bearings get som tough moves too.
(This is commercial for an oil brand, but can be absolutely right anyway)

https://www.transdiesel.com/blog/passenger-car-motor-oil-blog

"So while API SJ, API SL, API SM and API SN PCMOs are perfect for modern petrol engines, they may not be ideal for older engines, especially those fitted with flat tappet cam followers.

Because of the high sliding load of flat tappet cam followers on the camshaft in older engines, a higher level of anti-wear agent is desirable to prevent cam lobe wear. The perfect anti-wear agent for this job is our old friend ZDDP. And ZDDP at the concentration of previous API SH engine oils. Larger engines also seem to benefit from higher viscosity engine oil, such as an SAE 20W-50."

Been running Darky on it for a long long time without any issues at all. 70,000kms at least.

That's all folks beep! beep!

Terry in Australia · « **Reply #91 on:** March 30, 2021, 08:28:38 PM »

Thanks Per, but the things that need to be remembered is:
1. Any cheap car oil produced today is superior to the oil that was available when our bikes were new. (before there was ever such a thing as "Motorcycle Specific" oil)
2. Over the last 50+ years of operation, all our bike's internals will have "work hardened" so are probably less susceptible to wear, or they're already worn out anyway.
3. Until I built the K0, I ran this oil in all of my CB750's, without issues.
4. All of those "Motorcycle specific" additives somehow makes motorcycle oil cost around twice as much as quality car oil, and
5. I've only had oil issues on CB750's since I started using "Motorcycle specific" oil.

For all of those reasons above, and the fact that I can't think of one good reason to keep spending big bucks on oil that doesn't appear to be doing anything special over the cheap car oil we've been talking about, I'm gonna do an oil change at the 500 mile mark (it's already done around 250 miles since I built that engine) with the cheap car oil and a new filter, and see what, if any, benefits/disadvantages I notice. I'm betting there won't be very much of either.

That is a very eloquent explanation Terry. And to the point

Mine would have been-" From experience I know the cheap slippery brown stuff works."

I've notice it doesn't seem to froth like oils did in the late -70s early -80s and leave milky deposits in the rocker area when doing smaller slower trips.

PeWe · « **Reply #93 on:** March 30, 2021, 08:57:12 PM »

There are also newer motorcycles with catalytic converter that differs from the old CBs needs.
So all Motorcycle oils are not targeted our belowed CB's with most likely wider tolerances in general that need higher viscosity upon the correct antifriction that does not make the wet clutch to slip. Not the starter gear either.

I use race springs that make life harder for rocker pads and lobes. (Heavier stock stemmed valves)

I noticed that engine was easier to rotate by hand when it had the head with 5mm valve stem kit which used softer springs when valves are very light.

I guess the additives in oils have not that long shelf life. It would otherwise be fine to find a NOS oil from the early 80's.

Keeping with the specifications the manufacture has stated is the real key I think and just do regular oil/filter changes.

If I bought a brand new m/c tomorrow the first thing I'd do is cut the filter replacement millage to half what is recommend by the manufacturer.and do the oil at the same time with an oil within the specifications the manufacturer stated.

Personally I think a lot of people get sucked in to using products that they don't necessarily HAVE to use to have the same outcome. but use it anyway due to ads, par-pressure (it happens a lot in forums similar to this one), lack of knowlage/experiance, it sounds cool or quite a number of other thing. Best to go back to first principals-What has the manufacture of that m/c specified?

caluser2000 · « **Reply #95 on:** March 30, 2021, 10:24:20 PM »

Did I mention I loooove oil threads

PeWe · « **Reply #96 on:** March 30, 2021, 10:48:18 PM »

Oil threads are needed.
The oils have changed. A very good modern oil is not always good for our old bikes.

I like (my gearbox and engine like) the semi or full synths for wet clutch with higher dozes of ZZDP.
I have recently used Spectro HD oil (mineral), Eurol Harley Davidson oil (synth), Red Line motorcycle oil (Esther synth).
All 20W-50.

I have some Red Line 20W-60 I ordered 2018 when summer often was over +30C making oil pressure lower when engine was hotter. Oil temp in tank often at 120C.
I use it as a ZZDP additive, max 1/3. Not too much, starter gear slip. (My K6 with CB900 DOHC starter motor, 800W and stronger gear ratio.)

Mixes of all with a cheaper Q8 SBK RACING 10W-50 (synth for modern bikes. Spectro and Red Line oils give spades of ZZDP anyway)

CB750 gearbox feels much smoother with those oils. Finding neutral when hot is another indicator.

I'm sure there are others that can do the trick too.

I might have to try this gulf western stuff.
I have been using Castrol 4T for years but have noticed the last couple of years, that if I don't ride the bikes often, the clutch sticks. It's never been a problem before.

I'd never heard of it until I went to our SuperCheap Autos for an oil filter for my CB750F2D Integra. While I was there I went for a walk around the.oil shelves. Saw the GW 20w50 at their normal retail price and thought it was not a bad price at the time so got a 4ltr pack and used that in the 750s oil/filter change. No problems noted so went in to SCA again and it was on special so I got two 4ltr packs and that was that. Been using it on all my m/c ever since.

All the bikes I had at the time had at least 50.000kms clocked up.. Some a lot more.

I go into Tesco and buy mineral diesel oil and change every 1500 UK MILES with filter every time
