So... I needed to find a Master Cylinder for the SRX that worked with the switch block, had a rear mirror mount and was suitable for the twin disc setup and after lots of searching and comparing caliper sizes etc I found a Ducati Monster SR2 800 Dark Master... and it fits nicely, has a nicely engineered lever with lots of adjustability (as you would expect) but what I am interested in is the Union bolt at the Master. The hole in it is tiny compared to the other couple of masters I have (Japanese units). Now my question to those who are versed in the mysteries of Ducati (or anyone else really) is... does the smaller hole ensure better "feel". It is a Brembo Master and for the $$ was a good buy... I am just interested in the small hole vs probably a 4mm hole in a Yamaha one I have (it wouldnt work with the switchblock).
