You made me laugh when the old oil spilled out after being knocked of the thingy. I had poured out a glass of Rosse's lime juice 29 mins before. My housecoat caught the tray handle and over it went all over the counter top and soaked the tea caddy the kitchen tissue roll holder, a can of rice, the coffee jar etc etc etc ! Whilst murmurmuring very rude words I managed to say "Now thats God's punishment" quite what for I don't have a clue, but you made me laugh. Good handling of the fork's oil though :)
G'day Paul, well done, l have always refilled from the top off the forks, knowing me l better have plenty of fork oil on hand, also you could put a couple of rubber "O" rings on the oil pump arm and roll them up to the filler hole to stem the loss around the sides, cheers mate, Neil 🤠.
Good idea! I shouldn’t worry too much about some oil dripping out as, in my experience, there’s normally about 20-25ml left clinging to the internals when you drain them in situ. In other words, putting a full 190 in (through the top or bottom) will inevitably over fill them unless the forks have been inverted, pumped out and left upside down over night. It is of course, not an exact science!
you can actually get Syinges large enough, I have one with a pressure guage on the top for doing Motorcross forks I think its nearly 200 cc But you are right about checking fork oil ...I assume my enfield has oil ... and u know about assuming !
Nice idea but I don't think it works as well as you think. The air in the fork has to go somewhere as you pump in oil from below....so it blowouts too much as you are filling. Maybe with a zerk/grease nipple type check valve in place of the drain plug, loosening the top caps to let air out? With a zerk, you can also fit a bit of hose on a 50cc/200cc syringe to get er done easier.
Would it be quicker to make an adaptor to fit the drain hole which would take a piece of tube, then using a big syringe to push the oil in, in one go? I have a syringe touted for garage use, available on line for about a tenner.
I have found sometimes the forks don't drain completely unless the top caps are removed. It is also a good idea to measure the amount of oil that comes out: were the legs equally filled? Was there enough oil? If the oil quantity seems OK then you can replenish the same amount to avoid overfilling e.g. if 190cc is called for and 180 cc comes out then assume that 10 cc is sticking to the insides and refill with 180.

I imagine it wouldn't be too difficult to make a tool for that but I like your practical approach.
Paul, pump your oil can till it stops pumping then add 190 cc of oil and repeat, save all that counting! Great idea though.
Great point!

The stuff that came out was surprisingly clean. Looks as if this bike has been well looked after. Forks are so often overlooked.
I would loose count, i know i would.
Me too!
The 10 second jump forward made it a quick job. 😉

I pumped the forks with the drain plugs removed until oil stopped coming out and only air came from them.
Genius
Did you try loosening the handlebar clamps and just turn the handlebar upwards a bit to clear the fork top nuts?
I thought about it, but decided to try the way seen here for the first time
Now Paul just pour it in the top of the forks or am I missing something love your channel by the way
Sometimes that is not so sraight forward, which is why in this case I did it as you can see here.
Maybe a disc brake bleed nipple fitted in the drain hole.
Does the front brake drum with the cooling / lightning holes as standard ?
Yes, on some BSA models.
One trick that works is to put a piece of rag over the spout of the oil can
This will make a seal if you are not spot on with the oil hole
just do it properly ,whats a few bolts to undo,you have no real idea how much went in ,your just presuming each pump is the same volume
Each pump was the same volume, I counted the number of pumps. Job done, thanks.
