Brake master

Can anyone tell me if a 2005 FJR 1300 Brake M/C has a 14mm or a 15mm piston?

15mm.... IIRC  Leon just went thru this. He bought a FJR m/c thinking that it was a 14mm.....I use a 2002 FZ-1 m/c which is a 14mm Pat

Actually Pat, I am using a 2004 FZ6 front brake master cylinder.

I bought a 2003 FJR "clutch" master cylinder, with the thought of running a double clutch spring set-up at some point.

I bought the 2006 FJR master cylinder and it was a 15mm.  I am still using it and it's way better than the 5/8th OEM one.  

Watch out for the brake light switch though, there seems to be some sort of mix up there.  The one I bought from Boats.net works opposite of the FJ's.  Seems that this might be a mix up at the factory in Japan but I could not get a data sheet from Yamaha USA to verify this.  I went to the FJR owners and got a somewhat straight answer from them after much prodding that the switch is built incorrectly.

Seems that the other forums I have joined and then left do not have the same comradeship as the this one.

For those who don't want to do the math, 5/8" = 15.875mm.  So a 15 is a little change, and a 14 a bigger change.

Yep, it was Craig...so much for IIRC

somebody clear this up on the brake masters.

are all fjr masters the same or is there different bores for different years?

I know the handles are different.
