You work on the bike, spend the money on a book.

the tank you made is fine that is there as extra. the thermostat problem easy fix, type this into your google search.... koso water temp sensor adapter .... this is a adapter that goes in the water line it's self. simply cut the radiator hose and put in the adapter then screw in the temp sensor and run wires.
Send me some pictures of the bike. I love the smaller bike I'm working on a bandit 400 and a gt 250.
Good luck

check your air filter...trust me...

I don't know what you have in New Zealand, but you probabley will want to use the premium (best grade) fuel. You can fix the current tank full by adding an octane booster available from a local auto parts store.
You could do some math and figure out if it's worth useing octane booster with cheaper fuel..

Make sure your fan is working correctly.If it is check your thermostat. Hope this helps

It is better to replace it with a performance version. K&N filters sells them on-line and you will be very pleased with the results. Changing your spark plugs to Denso Iridiums will also provide a little power boost (HP up) and improve fuel economy.

does the engine turn over but not start or does it not turn over at all

you should have a header tank some where on the bike you fill this to add water to the rad.

If you mean the bottom of the tank then one goes to the carb and one is just a breather/overflow that gets ran down out of the way and doesn't connect to anything. If you are talking about the carbs then one goes to tank and one goes to the vacuum
