master cylinder options

[Norm Keller]

If you check the piston size where it protrudes from the open end of the cylinder, that should give a reasonable measurement. FWIW, I have one of these on my bike: http://www.ebay.com/itm/7-8-Front-Right-Brake-Lever-Master-Cylinder-for-Kawasaki-Ninja-250-500-R-ZX10R-/370886528553?hash=item565a8f4e29 I shimmed the lever where the two sections connect and placed two dimes onto the end of the piston, between piston and lever. The end of the cylinder prevents the dimes from falling out and a dab of RTV silicone insures that they can't. If you do shim and use RTV, likely best to bungee cord the lever until the RTV is dry so you don't introduce a compression bumper into the lever. The 250 Ninja is a 10 mm master complete with reservoir and brake light switch. For $25.00 it's not an expensive experiment to see that you like the effect. It's worth keeping in mind that the reduced displacement from the smaller piston makes engagement more critical, which is why the shimming was required. I don't know if the smaller master would be satisfactory with stock rubber front brake hose. I could pull the lever to the bar with the stock one so it required fitting to provide enough displacement with the smaller one. ------ Original Message ------ From: "zoot" To: DSN_KLR650@yahoogroups.com; "Norm Keller" Sent: 2015-01-25 8:40:55 PM Subject: Re: [DSN_KLR650] Re: Master Cylinder options
