No chance of the new old master cylinder arriving till tomorrow so I’m going to get on with the following:
- Change coolant
- Increase coolant pressure release from 1.1 to 1.2 bar
- The expansion tank is constantly empty. This used to happen on my GPZ900R back in the 1870s and I cured it by upping the pressure release. Let’s hope it doesn’t cause a catastrophic fluid release instead.
- Get Scott oiler working
- Check spark plugs
- Actually, I’ll be very tempted to replace them with iridium ones, anyway. There are many reasons to do this but, for me, the main reason is that the iridium we use in spark plugs is harvested from asteroids!!!!!
- Improve wiring of ancillaries
All of this requires me to quickly whip off the fuel tank… (pauses for effect) ha ha ha ha. Tiger fuel tank is a big plastic Tupperware thing sculpted to fill every available cubic millimetre between the engine and frame. And around the headstock. Some of it manages to wheedle its way under the battery holder.
Later…
Spark Plugs

Why do we still carry these things? When was the last time you extracted a spark plug at the roadside? I’m leaving this out of my tool kit from now on.
I can’t get them out. I’ve been carting the usual box spanner type thing around with me but it’s too short. Come to think of it, I think there used to be a hefty allen key that acted as an extension. I need to either find something similar or use a socket set.
Scott Oiler
Scott oiler has a split piece where the vacuum hose meets the injectors. They sell Scott oilers at Polo Motorrad, just down the road, so I’ll go there tomorrow, grunt a bit, and thrust it in the guy’s face. My German isn’t very good.
