Hi Joel, ok i am also no $$ person, so i use cheap stuff for my
bike. U must think lor, we TZR is 10 year old bike, semi synthetic
stuffs are good anough lah.
Engine oil i normally use normal one i can find lor, i change it
only when i think my changing of gears are very very rough... which
is about 2-3 months.
Plugs i use those $2.50 can oredi. NGK one.
2T i use Esso Phase Green one, even cheaper than your Silver bottle
one, hehe
Your carb please wash it every 6 months. Coz TZR fuel tank, it will
enter water on rainy days. That time i never service carb whole
year, that day cannot start, carb and fuel tank stucked with too
much rain water...
Always bring an extra spark plug, some tools, alan keys, small
spanner and screwdriver, just in case lah, u never know when it
burns out lor. 
For petrol wise, ours is old bike, so using Octane 92 petrol will
be better. Also can use 95 and above fuel, just depends on what u
like lor.
I ITE time everyday use Shell XO. But now i everyday use Shell
Fushion 92. hehe
And also pls check your radiator everyday. Open up and see if
inside got water. TZR have a common problem, gets overheated
easily. 
hmm rest i oso dono, if u have problem just gimme a call.
