How exactly have I made it difficult? Instead of ‘approximately’ I take a moment to weigh it and put exactly the same back in - I don’t need ‘approximate’ but have it correct first time and I don’t need to top up, etc. It takes me no more time to do it than the usual method and probably less time, yet somehow you conclude that I’ve made it ‘so difficult’.

I can’t believe people are losing their minds over something so simple and so unimportant… :rolleyes:🤣

No-one cares what you are doing.
Just stop commenting about oil in a thread that is made to be discussed about the master cylinder.

It’s my thread - I asked the question!!

And I didn’t bloody well start this oil change discussion FFS!! I was asked how I do it by NapoleonDomestique while he was doing his usual nonsense!!

And if you don’t care then why bloody comment?!

Good grief… 🫣 Unbloodybelievable…

WTF?

Why would I want to start a thread about it? I wasn’t even interested enough in the subject to start a discussion about it…

Stock 2023 V4R front master cylinder

I have experience in correcting the stock setup. All it took was some good brake fluid and proper bleeding technique. Easy as. Cost me $50 and 15 minutes of my time. Sorry to hear that your lever is flaccid... That long? I hope you are better at bleeding brakes than you are at putting...

And I said I didn’t start the discussion about it… and I didn’t.

You’re really not as smart as you think you are yet, in classic little-man syndrome style, you have to constantly try and prove something and win at internet.

I can’t be bothered to respond further to your nonsense. It will only go over your head…

Which master cylinder have you bought?

Definitely trying the 19x18 billet, because I realised that I’ll need a 19 for my SportClassic build (just decided on the wheels and ordered them), so if this is no good on the V4R then it will be used on the SportClassic as I need a 19 regardless.

If it’s no good then I will get a 17 and I’ll let you know, so you can tell me you told me that 48 pages ago, but at least I won’t have wasted my money because I need a 19 anyway.

The 2 valve Ducati's have the worst intake ports known to man. You can get 30% (seems impossible right) more intake flow by making the port line of sight and cleaning up the seats. And with no enlargement of the minimum cross section (no port velocity loss) so more torque everywhere. Utterly transforms the 2 valves.

That does sound impossible.

The SportClassic is a lot of fun to ride, but it’s going to benefit a lot from lighter wheels, better brakes and a suspension upgrade (probably Bitubo cartridge rather than replacing the forks entirely).

It’s got a bit of a stutter when opening the throttle but I think it’s because the original exhaust and ECU were put back on when it was sold to me without resetting the TPS. I might put the Termignoni back on with the other ECU and see if it sorts itself out. The dealer doesn’t have the kit to reset the TPS on the older bikes…

A built 2 valve (I'm so old I raced 2 valves) as a 944 would make 105-108 wheel HP. You could get them down to about 330 lbs. And a 55 inch wb. Wide spread of torque. If I was going to Deals Gap this is what I would want. Utter weapon in the tight technical stuff.

That weight with that power at the wheel would be entertaining... The stock bike already feels light and nimble and that’s before the heavy stock wheels have been changed for the OZ Gass wheels that I’ve ordered.

It’s more fun on the road than the rather serious V4.
 
In the tight stuff way more fun. On my race bike I took the flywheel off and moved the crank ignition triggers onto the end of the camdrive. No FI, 41mm FCR flatslides. Snap wheelies anyone. Really fun, and flickable (steep and twitchy) and would flip side to side like nothing else I've ever had. But in the end by the time the 916/955's were everywhere everything you gained in the twisty bit's you gave back on the straights. Sorta like a Yamaha in MOTOGP. Put some good tires on that bike and go out and spank a few high end liter bikes with it.

I think it's something specific to Ducati because of the levers and how they (the levers) span over the controls. OEM size is 16mm though. I followed the bleed procedure from the service video which results in a MUCH better lever feel. Highly recommended to do that before upgrading the master.

Okay, why am I now unable to find a video that I have previously watched? Did you provide a link before that has changed for some reason?

There’s not much room between the calipers, forks and wheels to get to the bleed valves… I emptied the oil from the reservoir, swapped in the new master cylinder and then bled the master cylinder until there was no air. Did a bit at the calipers and didn’t see any air, but I’ll have another go tomorrow when I’m sober.

I think we are pretty much there though!
