R100 master cylinder

Hi

Probably been done to death but could anyone help with best size master cylinder for r100 twin Brembo .Have 15 mm at present but would like more feel.
I know 14 is the recommended upgrade but wondering if anybody is using a 13 mm .

Cheers

Some folks suggest that a ratio of around 30 to 1 is good, particularly with shortish levers like the BMW ones.
So the nearer you can get to this the better - Guzzi dealers will probably have a 11mm which will work well.
Forget the olds wife's tales of long lever movement, fitted and bled correctly you wont notice the difference after a few applications.
You could also try the soft and flexible Teflon brake lines if you haven't already done so - they will give much more feel than the rigid rubber ones.

Hi
Thank you for reply.
Am simply amazed at the lack of replies.
Have replaced old rubber lines with braided, but on you advice will go for 13 mm
Cheers
