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 ...

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...
