    I have been following a few threads and of course stealing ideas non-stop:) I have a 1980 650 that I have installed drag bars on, cause I want too......but the stock master cylinder is now not in the optimal position to provide pressure at all times....it should be level most of the time......so I have been looking for some time on a proper fix.

    These look promising:

    Question is, what to do about the switches for the clutch and brake light?? Ideas? Someone must have used these by now.

    Thanks,

    More reading and now I think I should just use a SECA master cylinder with a 14mm bore........thoughts? Which model/ year will do the job?

    Application notes:

    a) because the stock OEM master cylinders on XJ650 Maxim/Midnight Maxim, the 1983 XJ750 Maxim/Midnight Maxim models, and XJ1100 models is designed to be used on the stock curvy "buckhorn" style handlebars, the stock master cylinder reservoir is oriented at a "tilted" (from horizontal) mounting angle. This "tilting" allows the mirror to be properly aligned for the use with the stock buckhorn bars and keeps the reservoir in a relatively level position.

    b) the aftermarket master cylinder HCP1808WO is designed to mounted on "flat" (or, at least, "flatter") style handlebars, such as the ones found originally on all XJ-series bikes (except the XJ650 Maxim/Midnight Maxim, XJ750 Maxim/Midnight Maxim, or the XJ1100 models.....all of thsse models used the curvy buckhorn style bars). All other XJ models use fairly flat handlebars, and thus the replacement HCP1808WO master cylinder will work on those bikes correctly, with no concerns; it will leave the stock mirror mounted in the proper orientation.

    c) thus the aftermarket HCP1808WO master cylinder is going to leave the stock mirror tilted at a rather crazy and semi-useless angle when installed on any model that had those curvy, "buckhorn" style bars, and we do not have a stock-style mirror substitute that "solves" this problem. About the only solution we offer is to use the "bar-end" style mirrors, which attach the mirrors to a mounting stem that fits inside the end of the handlebars (which requires modification of the grips by cutting away the rubber on the ends of them).

    d) Also, on the XJ650 Maxim/Midnight Maxim models, the fluid outlet port (where the brake hose attaches), is facing "inward", towards the centerline of the bike (when the forks are pointed straight forward). The replacement HCP1808WO master cylinders have their fluid outlet port facing straight forward, and therefore your stock brake line has to be contorted to a rather odd angle to make it reach and fit this forward-facing outlet port. We do have available modified rubber or braided stainless steel brake lines for use of the aftermarket master cylinders on these bikes; their end fitting is rotated by the 90-degrees and extended by an appropriate length to allow it to attach to the aftermarket master cylinders properly.

    hope this helps
