Project Z750 part 4

I thought that the injectors were probably gummed up, so I put some injector cleaner into the fuel hose and left that for a few days to see if it could get through and unclog the injectors.
So after more than a few days (i.e. when I remembered) I put the tank back on the bike and hooked up a battery. I crossed all of my fingers this time (waited until after I'd connected the battery) and pressed the starter.

Was my luck holding? No of course not. it's never quite that easy, so I poured a little fuel into the injector line fuel hose, hoping enough would get through to at least hear the engine try to fire. still no luck.

Now I already understood how carburetors work, by allowing fuel and air mixture through. I hadn't realised that fuel injectors don't just let fuel through, but fire it through under pressure (yeah, I know it's kinda obvious, but my brain must have been having a holiday).

My wife suggested that the fuel pump could have gone through the alarm and so the wires that I had crossed my fingers and attached to each other might not be quite right. okay that's a good idea, so what next.

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...

Creating a Watch Face for Android Wear OS 2

Step 1 - Setup my watch for development I have wanted to create a watch face for android wear for a while, but as no new watches were being released my old Moto 360 watch running wear os 1.0 got out of date and I stopped using it. For Christmas 2018 I got a new wear os watch running wear os 2.2 (android os 8.0.0). it has a round 400 x 400 screen and I decided to finally get round to creating myself a custom watch face for it. The first thing I do with all my android devices is to enable developer options. if you don't know how to do that then you can find the method using a google search. I won't give it hear as it opens up all sorts of options that could make android become slow/unusable. Once I had developer options enabled, I turned on USB debugging. This watch (as opposed to my old Moto 360) has a USB connection to the computer, so I don't have to use WiFi debugging (which has to be set up for each debugging session). now on to the watch face creation. St...

Project Z750 part 5

As my other bike was going in for service I decided to ask them their opinion on the fuel pump getting gummed up with fuel. they said that it's not common, and that the alarm is normally attached to multiple systems common ones being the fuel pump and the tip over sensor (as well as the kill switch) okay, so the next step is to put power to the fuel pump and see if it works. tank off again, up on the bench and create wires to go straight from a battery to the fuel pump connector. once the wires were ready, I attached the ground lead to the fuel pump connector and (making sure I didn't short the battery) touched the live battery wire to the other connector. viola power direct to the pump, but absolutely no sign of life, no humm, no vibration, nothing. okay, are the wires connecting properly? multi-meter from battery terminal to ground wire connection on tank. yep that connection is fine, no resistance. so switch the multi-meter to volts, ground multi-meter probe to same...
