The main thing on master cylinders is that you get the same 14 mm piston bore size as the Valk so braking isnt effected.
Good info. Thank you.
Looks like the CTX1300 front brake master cylinder uses the same piston set as the original Valkyrie, the new Valkyrie uses a similar but different part number. However, the clutch master cylinder piston set for the CTX and the new Valkyries have a different part number than the original Valkyrie. I honestly don't know if it would make a difference on the clutch or not. You can't buy the piston itself separately, so the difference in part numbers could just be due different bushings, boots, or springs. It could also mean a different piston of the same size, a different size piston, or any other combination. I would think that if it works for the 1800 clutch it would work for the 1500 clutch, but I don't know what I don't know.... I could buy a piston set from the newer bikes and measure if necessary.
I'd appreciate your thoughts. Thanks.
