Quite a few sites mention 145-150 cc.
I did wonder if there were variations in volumes due to any change in the design of the fork internals.
Can't rely on the fluid I removed as a measurement as one side was very low.
I'm intending to use 10W fork oil.

I read that Honda used ATF in the early days - which of the many ATF grades did you use Dexron 2 ?

I used it in the car aswell
If you have an auto box in the car,
Change the oil!!
The box will last much longer

I've run an automatic car for over 30 odd years now John - I always used to do the double oil change, the second one being a 100 miles or so after the first one to allow for the Torque convertor. Sadly they started to make changing your own transmission oil difficult or impossible initially by the removal of a dipstick, so they can only be done by machine via the drain plugs on newer vehicles. I was a stickler for changing the pan filter as well. Never had an auto box go faulty.
As is the way I gave away the last of my ATF stock a couple of years ago.

I read that in the very early days Honda used fish oil in the forks!
Just the plaice for it I'd imagine.
I'm sorry, I just have no sole :o

Quantity, not super critical in these. Enough to keep damper valuing covered through the whole fork travel and not too much that the oil hit the top cap under full compression to give hydraulic locking. Hence the reduced volume on refill to take account of residual quantity left inside when drained.
Heard the fish oil stories before, but don't recall reading definitive confirmation, sounds like it was quite smelly by all accounts.
I use specific fork/damper oil currently to n help with bush and stanchion friction reduction.

Back onto the subject......I had 10w grade in the Norton forks but was told to use 20w grade so I drained the old oil out and replaced it, I couldn't tell the difference! Maybe it was just old technology used in the construction of the dampers etc?
Post by: K2-K6 on December 18, 2023, 10:12:35 AM
Yes to some of the older dampers having very little in the way of accurate valuing or control in hydraulic terms to be very responsive. Many didn't have much compression or none at all, just some on rebound to stop it being really bouncy, that's as I understand it. Some logic to that, but not to what we expect nowadays.
Anyone familiar with old Morris (BMC etc) type lever arm dampers will know that they got there much before Suzuki made their "killer" V-twin rotary damper, reputation destroying chassis ;D you could use beef dripping in those Morris type :) (that's a joke delta :) ) and find improvement by leaving the minced beef in there too ;D

VW ID3 rear brakes, for example, are drums....closely resembling "minifins" if you used them.
Quite large diameter and so fairly high braking torque, they dont in reality need much heat management with regen braking strategy on them. Also advantageous is that they dont go rusty from lack of use, especially in Scandinavian climatic road conditions where rusting disc etc appear to be a vulnerability within a modestly driven vehicle.

Top Tip
Obvious to the experienced - if changing oil in situ do one side at a time - otherwise the front wheel dips as the springs are pushed out so fitting the caps is more difficult. I actually used a large rubber cork & jammed it between the right fork top & the master cylinder to hold the suspension down as I fitted the left cap.
