OK, so I read all 22 pages here, and 50 pages on .net and have come up with more questions;
While most 450R/CRF/CR master cylinders are using an 11mm or 3/8" piston, they are operating with a single piston caliper.
The 250R uses a 14mm piston, and a dual piston caliper.
No one mentions any incompatibility with the caliper vs. flow needed to apply a dial piston caliper vs. a single piston caliper.
I do not want to increase pedal travel by using a smaller based master cylinder or worse, run out of flow due to piston travel/pressure because of same.....................
Anyone have any answers or input
