Leaking Rizoma's
I have Rizoma Master Cylinder Reservoirs fitted to the GT.
Every time I get home from a ride there is fluid on the outsides.
They are not overfull or leaking from the hoses.
Has anybody come across this problem, and if so how did you fix it?

Where exactly? Both leak? is it near the top? Maybe a pic?

Actually, if the fluid is any higher than the top of the window, you ARE overfilling them. The pressure builds and it weeps out the caps.

I've had the same problem for years.. it's just a slight weeping from the top of the reservoirs, most noticibly on the clutch side. it looks like it's weeping from the top but it only happens after aggressive riding. Maybe the bellows don't compress enough to allow for the expanding hot fluid returning to the reservoir and pressure pumps just the slightest bit of fluid out around the cap seal?

Thanks mate.
This sounds about right I think. Always there, but much worse after a blast. I will try reducing the level as far as possible and see what happens.

Ditto prev posts - my riz res did the same until I found the right max fluid level. Once set correctly they've never leaked since (for years)

It really is a function of having the level correct. And once you have it high and get fluid up into the threads, you really have to work to clean it out of the threads even when you lower the level. Brake fluid is a pain and will seep for many rides once you've had it overfull - I would clean the fine threads of the cap and reservoir with rubbing alcohol and let them dry before I put the cap back on.
