Project Z750 part 31


Right, new braided brake hoses have arrived, so all I have to do is drain the brake fluid, replace the hoses and bleed new fluid through again.

The new hoses went on without a hitch. the kit I ordered (from HEL) had everything it needed; new banjo bolts and crush washers as well as the hoses. It made everything simple.

So I put it all back together, fill up the master reservoir. brake bleed hose onto the nearest calipers bleed nipple and start slowly pumping the brake lever. As I pump the brake lever, lots and lots of bubble appear in the reservoir.

After about an hour of pumping the brake lever (and opening and closing the bleed nipple) I'm getting nowhere. Either this is going to take days, or I'm doing something wrong.

My vote; I'm doing something wrong. So "To the Internet". very few people drain the brake system and then fill up from scratch. Or at least very few post about it. There are some people who use a syringe and push the fluid up from the bleed nipple. But I don't have a syringe. I did find a video of someone using a vacuum bleeder, which made it look really easy, and logically it should work as it sucks the air out of the system through the bleed nipple and it's replaced by fluid from the reservoir.

so off to amazon and one vacuum brake bleed kit ordered.

fingers crossed, it works as easily as the guy in the video made it look.

Project Z750 part 18

I have done a bit of reading on how to clean brake caliper pistons, and found an article that said you could use fine wet and dry to clean corrosion off them [ http://www.motorcyclenews.com/new-rider/choosing-kit/2006/november/jan26-05-how-to-service-brake-calipers/ ]. as it suggested using 1500 grit wet and dry, I decided to be cautious and start with 3000 grit. I cut the wet and dry into strips about an inch in width. I put some wd40 onto a strip and started polishing the rear piston. After quite a while I started to notice the difference. it was getting cleaner. well, it was working, but it was going to take a long time. well, I was patient and I really didn't want to rush it and ruin the pistons. Over the next couple of weeks, I polished all of the pistons using the 3000 grit wet and dry. As it seemed it was going to take the rest of my life using 3000 grit wet and dry, I decided to take a risk and bought some 2000 grit. yep I was really pushing my luck here. I cut the 20...

Project Z750 part 3

I realised that this was going to be a little bit more involved than simply attaching a new battery and firing it up. I guessed that the alarm could be stopping the ignition circuit and that is when I found that the alarm remotes had non-replaceable batteries. I also read that if the alarm sits for extended periods with no power then it can be toast. So my next step was to remove the alarm. another Hmmmmm moment. I have never removed or fitted an alarm. I've never even looked into how they work and what they do, so this was quite a daunting task. I took the insulation off the cables that attach to the alarm. now we've all seen nice electrical systems with all of the different colour wires to make it easy to see what goes where, well this thatcham alarm had a very large bundle of cables and all of them were black. No help there. So I had a look at how they were wired into the bike's loom. there was a bundle of wires going to the rear, which I guessed were for the i...

I'm a Triathlete (again)

So, I've finally done it. I'm a Triathlete again. First a bit of background. In the 90's I used to work at Xerox in Hertfordshire. I used to run with the work club some lunchtimes, swim with friends on the other lunchtimes and cycle to work some days. Xerox had a small gym on site with a resident fitness instructor. Approximately every six months I would have a fitness test to see if I was getting fitter. it was a stationary bike test and they measured fat percent and blood pressure (probably a bit more, but it was a long time ago now). During one of these fitness tests the instructor asked what exercise I did, and told him, and he suggested that I have a go at triathlons. So I looked for magazines (This was actually before Google. Yes there was a time before Google existed). I found a magazine called "220 Triathlon" and read through it to learn more about triathlon and look for races. I'm not sure how I found out about it, but I was told about the ...
