Hey guys, can anyone tell me what the stock front master cylinder piston bore size is for a 1977 GS750 single disc?
The bike came with aftermarket levers and i think they're a 14mm master cylinder.
Ive had semi squishy brakes since i got the bikes. I rebuilt both the front and rear calipers today. The rear grabs great. The front grabs buts its definitely soft. I made sure to bleed them correctly. At first it fought me a little. I had an air bubble at the splitter block. I got that all sqaured away and its definitely soft. The rebuild kits went in great, i dont believe i have any issues there, however what I'm guessing is that the master cylinder bore might be a touch too small. Can anyone confirm stock bore size? Itd help me narrow down this issue.
