Project Z750 part 2

now I understand that petrol that has been left tends to emulsify and clog up delicate engine parts like fuel injectors and filters and that the piston rings can rust in place and seize the pistons, so the first thing to do is see if I can get the engine to run. I removed the seat, cleaned out all the wildlife that had taken up residence (by the way, did I mention that I really don't like creepy crawlies !) and removed the (dead) battery.

The first thing to do would be to start the engine, but as it had been sitting for a while, I didn't want the piston's moving in old oil. so task one was to change the oil and filter. an easy job.
Well, not on this bike. the sump bolt actually turned easily enough, and I thought it as going to be an easy job then I tried to unscrew the filter. no joy. it was stuck firm. so I gripped it tighter and turned again, it's moving. oh, no its not moving, the grips are moving but not the filter. I was gripping it so hard I tore off the outer body shell, but it still wouldn't turn. so now all I'm left with is about one cm of filter rim and  the thread attached to the bike.

Oh joy, an "easy" oil and filer change was turning into a nightmare. I eventually had to use a screwdriver and hammer it into what was left of the rim of the filter and hammer the thread round, but eventually it did come off, and  without damaging anything (other than the old filter). boy nothing ever turns out as easy as you think. at least I could now fit the new filter and put some new oil in the bike.

with that done, I tried pushing the bike in gear to see if the engine would move, but it didn't seem to work. the rear tyre just skidded along the patio. Next thing to try is some lubricant into the piston barrels, so I removed the tank so that I could get at the spark plugs. I removed two of the plugs and sprayed WD40 into the barrels and left it for a few days spraying a bit more WD40 every now and then.

why remove only two of the spark plugs?. because the layout meant that the outer two spark plugs were easily accessible, but the inner two were partially blocked by the bike frame! great design Kawasaki. I probably could have got them out with a lot of fiddling but at this time I just wanted to see if the engine was free, and I hoped that if I freed two cylinders, the other two would free up as well.

I then tried pushing the bike again, but it still didn't seem to want to move.

Next step was to attach a battery (or two in series to give me some extra capacity) and try to crank the engine over. I put the key in the ignition, turned it and everything lit up as it was suppose to. well that was good news.

I pressed the started and guess what. yep nothing, not a sausage. nothing. the engine didn't even try to turn over. i checked the kill switch, but it was in the correct position. All I'm trying to do is see if the engine is seized or free, why is it so hard!!!

okay, thinking time again.

Triathlon Training in the new year

So, my 2019 training has got off to a good start. I'm running regularly and my knees seem to be holding up. I've got a training plan to get me to a middle distance triathlon in September and I am managing the run distances I have set myself. I need to find some longer cycling routes to work and ones with a few hills too, but that shouldn't be a problem. my weekly cycling distance is okay, I just need to move to get my ebike to be doing less of the work. last week I did use my normal commuter bicycle and managed the whole four days as well as my runs, so that was a really good sign. Swimming won't be an issue, I have always found that to be the easy part of a triathlon (not that I'm fast, but I can keep going, and I did manage to swim the distance within the cut off time when I tried the ironman 70.3 last time) The main worry about going longer is my knees. I've got a 10K booked in late January which will test my knees out and I'm hoping that they hold ...

Windows Subsystem for Linux Internals

Background Windows Subsystem for Linux was developed by Microsoft to enable command line programs compiled for the Linux operating system to be executed on Windows. To explain the architecture I would like to show the evolution of OS design and how that has enabled this subsystem to be built. Dark Ages (or Back in the Day) Microsoft's MS-DOS was quite primitive in its design (compared to today's OS's). It is a single user OS that can execute one process at a time. DOS had an application programming interface to allow user programs to access some hardware in a device independent way, but only for character-based applications. This allowed applications to display graphical elements emulated with text characters as these screenshots of Microsoft word for DOS show: This is Microsoft Word version 1. To use these programs you had to remember key combinations to bring up the menus and used the cursor keys to navigate around the screen. If the a...

Project Z750 part 16

The piston puller has arrived. it looks like a pair of pliers, but works opposite so that when you press the handles the "nose" of the pliers expands. the idea is that you put the nose into the piston, grip very hard and turn and pull the piston so that it comes out. the theory is great, but actually using one isn't. in use you are trying to grip as hard as you can, and at the same time trying to pull the piston out of the caliper (as well as maybe turning it if it's stuck like mine). it took a herculean effort to get one of the pistons out, I was gripping as if my life depended on it, trying to twist the piston and pull it out of the caliper. when it turned (a little) it gave me renewed hope of getting both pistons out, and eventually the piston was out, so just one more left. so now on to the fifth and final brake caliper piston. I put the piston puller tool into the caliper, gripped with all my might (no laughing please) and twisted. Well something mo...
