The GPz1100B2 Tank Saga

I’ve written a few posts about my GPz1100B2 over the years, the most successful work has been getting it running with a 6000klm ride to Tasmania and back and the 530 chain conversion after the old 630 chain snapped 30klm from home after that ride! The least successful work has been the rust in the tank. So the saga continues…… …

GPz1100 Tank conversion & Repairs

Trying to find a 1982 GPz1100B2 tank has been harder than finding rocking horse poo. The solution I went down was to use a modified GPz1100B1 tank with the tap relocated. This tank came out of the blue when I started asking around for any solution to my B2 tank shortage problem. When I obtained the tank it was covered …

1977 z650 Wheel Bearings

As I start my Cafe Racer build based on a 1977 z650B1 I discovered that most of the wheel bearings are the same as a classic “Zed”, but the sprocket carrier is different. This led me to start recording minor details like wheel bearing part numbers so I didn’t have to research the same bearing information later. The 1977 z650 B1 …

GPz1100B2 January 2022

ResurectionTime Over the 2021 Christmas break I started to resurrect the GPz1100B2 (which is painted in ELR colours). The bike started first go which was very positive so I took it for a ride around the block a few times to see what it felt like and to check out the 530 chain conversion I did soon after returning from …

Replacing the zx9r Push Rod Seal

For a while now my 1994 zx9r-B1 has been leaving a spot of oil everywhere I parked, in fact it started to leave a lot of oil! The cause has been oil leaking past the oil seal for the clutch push rod. On the B1 the clutch is hydraulic, so there is a slave cylinder similar to the older GPz900R …

Master Cylinder Disassembly

This is my full-proof, gentle and non-destructive way to disassemble a master cylinder (in this case a GPz900R MC). Over time they become seized due to water absorption and oxidation issues. For a project bike I needed a Clutch and Front Brake master cylinder, I have collected a few over the years and they always come in handy. This one …

Replacing Wheel Bearings

Introduction Bearings are subject to wear like any other part of a Motorcycle, however they are under considerably more strain and therefore should be replaced at least every 10 years from my experience. Before you can begin to remove your old worn out wheel bearings and replace them with new ones you need a few basic tools, somewhere clean to …

GPz900R – Wheel and Swingarm Bearings

The GPz900R is a bearing suppliers dream! With Wheel and Swingarm bearings requiring replacement at least once in each bikes lifetime. On a GPz900R you have standard wheel bearings that Kawasaki and most bike manufacturers use and hence they are carried by virtually all quality bearing suppliers. Where the GPz90Rr differs from a lot of early bikes is the shear …

GPz900R No Valve Clearance left?

When I first opened up the cylinder head cover of a GPz900R many years ago I was surprised to see something I first saw in the late 70’s on a Honda CB750… “Rocker Arms” sitting over the camshafts, but with two valve adjustments on them due the the 16 valve head. Having screw adjuster rather than shims makes valve clearance …
