Rizoma Reservoir Problems

Just wondering if anyone else here has had problems with the Rizoma "Next" Reservoirs? I don't ride much, but almost every single time I do I have to bleed my front brake just one time at the handle bar to get it to work, but now I'm noticing that my clutch lever has become weak and I've had to bleed it as well. I never had these problems with the OEM reservoirs. There are no leaks anywhere that I can see. I have OEM brake calipers front and rear but the clutch slave cylinder is an Oberon. Again, I never hand any issues with bleeding before, but having to do it before every ride is kind of annoying. I realize that the ABS unit might effect the brakes, but I've honestly bled them at least 20 times since changing to the Rizoma tanks, it should be fine now. Using Motul RBF 660.

I must bleed my clutch after every ride. I do have the fancy Rizoma but I’m not sure it would be possible for them to be causing the issue.
Ill stop in my local Ducati dealer in a few days and see what’s up

I’d have the dealer check your slave cylinder and your master cylinder. I’ve had both go bad on my V4S.

So I actually have the Rizoma Wave style reservoirs and there are 2 tips to make sure they do not leak:

1 keep the fluid level lower than you might think

2: tighten them till they are very snug. My dealer put my clutch side reservoir cap on tighter than I would have myself after replacing my clutch slave cylinder.

reservoirs have not leaked one bit since.

however... even after replacing my clutch slave cylinder with the fancy DucaBike one, it’s still spitting out brake fluid from the clutch system and I have to keep bleeding the master cylinde. Maybe it’s time to replace that master cylinder too
