Brake master cylinder
« on: December 29, 2013, 12:41:11 PM »
So I want to change out the stock master cylinder on my '72 CB450 K5 and I was wondering if I could swap it with this: http://www.ebay.com/itm/310818155939?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649

I know they're some ratios that you need to keep in mind (master cylinder bore >> Caliper bore, etc.) but I can't remember. I'll still be running the stock caliper. Suggestions?

And yes, I'm sorry its a DOHC in a SOHC forum but I can't get answers elsewhere.
