Rear Master Cylinder Inlet Diameter

[Gweenz]

Hey everyone I have the HRC rear reservoir delete kit, doesn't fit on my Hawk the inlet is too big. Kit appears to be 5/16" inner diameter and the Hawk appears to have a 1/2" fitting. I thought the Hawk had a 5/16"?? Am I wrong or is this not the original MC, appears to be a stock Hawk one labeled "1/2".

This kit is specifically labelled for:

CBR 1000 RR Fireblade R1 R1M R6 GSXR

My delete kit is a piece of hose and a bolt. Works Great.

7/16" hose? I have 1/2" here but it's not very tight.

I used 7/16" ID hose with a cap purchased from the local Ace Hardware store and clamps on both ends.
Also purchased a HRC delete kit and the hose ID was too small,

Thanks! Just going to grab some 7/16" hose and go that route. The HRC kit tube is just colored vinyl anyway.
