Project Z750 part 29

So, I've got the fork legs back with the new stanchions, seals and oil. putting hem back onto the bike went easier than expected. I pushed one then the other through the yokes and lightly gripped them with the yoke bolts (making sure I could still move the forks up/down and twist so that I could adjust them as necessary).

Then I attached the mudguard. my reasoning was that it would make sure that both fork legs were the same height and rotated correctly (plus it had to be put on before the wheel anyway).

I then checked the top of the fork legs to make sure that they were the same height as before I took them off. I then put the wheel on which went on easily enough, but I can't torque it up as I don't have the right allen bits (more tools to order, oh dear!).

Once the wheel was on (which also reassured me that the forks were aligned correctly), I tightened all of the yoke bolts to the correct torque and dropped the bike off of the lift.

It's looking like a bike again, finally.

Next step was to attach the two front calipers and get some brake fluid into it.

Once I'd worked out which caliper went on which side of the wheel, I bolted them in place and attached the brake hoses. Next I filled up the master reservoir, attached a brake bleeder to one caliper, made sure all of the bleed nipples and hose connectors were tight and started bleeding the new fluid through the hoses.

it seemed to take forever to start getting any liquid out of the bleed nipple, but eventually, it started coming through. and yes, I did remember to keep topping up the reservoir (although it did get quite close to empty a few times).

once I'd got the fluid in one caliper, I moved to the other one and did the same. again, it was quite a while before liquid started coming through, but it did get there, and then I kept going until no more little bubbles were appearing out of the bleed nipple.

then I went back to the first caliper and bled it until no more bubbles appeared.

So, I'm done. Except that there was no bite to the brakes. OK, I tied the front brake lever in and left it overnight as this is supposed to allow any air trapped in the hose to flow up to the reservoir and be released when you release the lever.

Next morning, I untied the lever, and bled both calipers a few times. Still no bite at all. I could push the bike with the front brake applied and it would move.

So, off to the internet and after a bit of searching, I read some people saying that as the brake hose goes over the mudguard it can get air trapped in it (as the hose loop is higher than either caliper).

I also read that brake hoses should be changed after around four years, and as these ones were about ten years old, I decided to order a new set of hoses from HEL. the new hoses go from the master cylinder direct to each caliper, so removing the over the mudguard hose and the bleeding issue.

so another wait for parts.

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 ...

First race of 2019

As I am aiming for a middle distance triathlon in September, I want to make sure that I can complete it before shelling out the (rather high) entry fee. my main concern is that my knees cope with the run section which will be 21 Km (a half marathon). In the past, I have had a bit of trouble with my knees playing up. I thought it was because I had run too much (increased my training too quickly, too many races close together, that sort of thing). So for the last 8 months, I have been trying to acclimatise my knees by running around 5km three times a week To take stock of how my knees are with running, I decided to enter a 10K race. The race I entered was the Bristol Race For Chocolate 10K. It sounded like a fun race and was on 27th January, which would give me plenty of time to train for my main race in September. I wanted a 10K as it is just under half the distance of my target middle distance and if my knees cope with that then I have plenty of time to increase the distance...

Wales 500 Post 2

Day -1 (of the rally) So, tomorrow, Patrick and I will be riding up to set up our campsite ready for two days of (not quite off) roading. I've got my camping gear packed, but I've been getting confused about how to pack things that I will want whilst riding vs stuff to leave at camp. Then I realised that I've never done that before. whenever we've gone on a trip we've always stayed a night and then moved on to the next place. Only once have we set up and stayed in the same place for more than one night, and that was at Assen to watch the MotoGP. Guess I'll get it sorted today. I think I've got everything I need, except a way to pump up my tyres if I have a puncture. I have a puncture repair kit, but no pump. hmmm, will have to think on that. I think I will be taking a rucksack so that I can carry stuff out on the rides with me, but I may try to attach it to the back of the bike instead of wearing it as it might get too hot. Today is wet and rainy...
