Post by: argent brick on February 06, 2012, 08:33:13 PM
Can anyone tell me what year and model K75 fuel tanks will fit each other ?

To start with, any K75RT tank is out as they use K100 tanks.

I don't know the exact details but according to the parts catalog something changed in production month 1/93 so if you're looking for a tank for a 95 then you'll want to get a model year 93-95 tank from a K75 or K75S. (K75Cs were out of production by then.)

Jumping in with a fuel tank related question:  What's the difference between a Bridge-Mounted tank and a Plug-Mounted tank?  Most specifically, which version would a 95 K75RT have?  The repair manual gives a different torque sequence for the frame bolts, depending upon the style of tank.

Separate metal stamping (9) that "bridges" the frame rails and secures the tank using a single screw (8) through a tang on the tank.

Welded brackets on the frame accept 2 plugs, integrated with the tank and located on either side.  A rubber ring (14) in each bracket acts as vibration damper and "C" clips (15) firmly secure the tank to the frame.

Only early model K-bikes used the bridge mount. A '95 K75RT would use the plug mounts.
