Also if you have that sorted,  see Robert's excellent write-up on the temp sensor resistance http://www.motobrick.com/index.php/topic,11299.0.html
Starting at Reply #108, the coolant temperature sensor discussion was started. Soggz seemed to have tested it with reference to rbm's document, then indicated it passed inspection.

Well, most likely you have a massive air leak on one of the cylinders,  most likely the one, that stalled after hosing down with contact cleaner.  Use a straw and localised puffs of spray to determine,  where is the leak.

Btw an engine lugging, needing a lot of choke and thumping sound like only two cylinders working

Ok,managed to start it up today.Before I did that...
Checked the spark,nice and fat and blue.
Compression readings good. But still running rough.
Sprayed contact cleaner at no.3 carcuss,and it stalled.
Going to check the valves in the next couple of days when I have time.
The revs on it sound ' intermittant'.
Choke only seems to work when it's warmed up a bit too. On start up,throttle needs to be wound up and down a lot,and choke dosnt really work for a while,until about 5 mins in,then goes up to 4 k on full,2k on half.Take it off,and bike stalls. What does this sound like?
Thanks.

In OZ I can go down the road to the local brake shop and get them made up virtually on the spot, at a good price. Half to a third of the price the local motorcycle shop charges.  He'll do a OEM copy in the rubber or steel braided. My neighbor has a mobile business doing any sort of lines fitted to any sort of vehicle.

To save damage to the belly pan you need a front mudflap. These are now thin on the ground and expensive, try this link for a slightly cheaper solution .90 cent . It's coming up to three years old and still going well. I have also worked out how to do a rear mudflap by slightly varying the method but as I don't really want a rear one I haven't tried it yet. If any body is interested I might give it a go when I free up a bit of time.   http://www.motobrick.com/index.php/topic,7914.msg57660.html#msg57660

Wow, $8.80 to ship to you, another $30.60 to cross the border. I'm not in a hurry, still have the original scratched screen, so let's do that.

Szabgab when I first started using the tape it came in three widths 100mm, 50mm and 25mm. I used the 100mm and 50mm on the tank. I don't use the tape on the belly pan any more due to it being labour intensive. It requires a lot of pattern making and cutting and molding with a heat gun and had to be made of three 100mm strips for the front two vertical sides on either side of the pan and one horizontal across the lower edge. The belly had four 100mm strips butted up from front to rear.  The trouble with the tape on the belly pan was that after around 8 years water would eventually work it's way under an edge allowing it to peel. The second time I replaced it was due to damage from a prang and it was still holding well after approx. 7-8 years.The stuff I found  Ali is only 50mm wide, but there is sure to be more around in larger widths it might be worth emailing the supplier of the 50mm strips. If it is still available in OZ it has got to be available overseas  I would try boat and marine supply shops as that is where I found it in three local marine shops. Now there is only one stocking it in black and white in 100mm widths.

Martin,  this is great,  thank you.  I was also thinking getting the belly pan done in truck bedliner,  if it withstands all sorts of stuff being dragged on it many many times,  surely it would survive a stone or two thrown at it by the wheel.  Also in that case it would be paint it once and forget about it forever,  the stuff is basically a thick layer of PU plastic...
