Have tried the battery as that was flat but still will not start with a recharged battery. The bike was running before I put it up on a stand and took the tyres off to get a new set. Since fitting the tyres back on it just will not start.

check for short circuits. it can be stripped wire that makes contact with the bike chassis. This can drain the battery. Also, Charging circuit may be dead (alternator and regulator).

Yuasa batteries are expensive but with good reason. They are extremely high quality and follow the old adage 'you get what you pay for'.
Cheap batteries appear initial good 'value' but the extra investment will pay dividends long-term, if properly maintained, your Yuasa will last many years.
If you suspect the liquid is acid, neutralize it with some baking soda just to be sure. You don't want that dripping onto anything metal or pain, causing damage.
Once you have it neutralized, wash it out with water.
It sounds like you ride infrequently and bike may have periods of serveral weeks on occasion without being ridden.
My recommendation would be to install a quality replacement (like the OEM Yuasa) then purchase a battery maintainer that you can plug in while bike is not being used. Good maintainers are Optimate and Battery Tender. (I have both myself - I really like the Optimate 4.) Both of these come with a waterproof 'pigtail' harness that you can permanently connect to the battery - then when you put the bike away, you can simply connect up to it without having to remove anything.
Hope this is helpful.
Good Luck!!

Alex ,
the battery is not your problem . it sound more like the starter motor giving you grief or alternator or regulator .
The electronic system on these are Bosch which are very sensitive to fluctuations of power .
Now when your starter draw power it really sucks power out of your battery and hopefully you have enough for the rest of the appliances .
the hard line of all this is that the battery may look good and hold the charge for a while but once the starter motor draw power to start the bike , you have very little power left to service the rest of power needed for the electronics . Make sure the alternator give you enough charge , test it while running , it should give you between 13.5 V to 14.8 V output or see if you accelerate the bike the headlight becomes brighter . If the light stays dole or dimms while giving a bit of gas , your alternator or regulator has a problem and will have to be tested and replaced .
have a look at all this and let me know how you go

No, very unlikely that the battery has anything to do with this problem
When you changed out the battery, did you remove the fuel tank completely or just prop it up??
There are two fuel lines (supply,return) and an electrical connector for the fuel pump that must be disconnected when you remove the tank.
I would suggest taking a close look on the RHS of the tank near the seat and ensure that the fuel pump connector is properly seated and that the fuel lines are properly connected.
Good Luck!
