Answer 2

10w30 motor oil or it may require 'non detergent' 10w30. You can find straight 30 weight non detergent motor oil at any auto parts store.

Answer 3

Use Type "F" ATF,,,aka Ford-type automatic transmission fluid.

Or,,if you can find it  & wanna spend the money...

BelRay Gear Saver 75w .

is hard to beat.

Hard to beleive here in the 21st century,,,

people are still being told to pour Engine Oil into Transmissions.

If you prefer to  continue using Engine oil,,,

keep in mind that oil has changed a bit since 1950's  when the j**s started using it because thats all they had.

Lots of oils are bad news for modern clutch friction compounds.

Careful which one you use.

ATF is "Extreme Duty  Clutch Oil",,,always has been.

Thats what its designed for,

So,,,any ATF is Clutch-Safe

Answer 4

yamahas own 10/40 will do...by the way the tzr50 doesnt have ''gearbox oil'' as such...its engine oil....as for the performance NO motor oil will make it go faster...remove restrictions from the exsaust pipe,carb and ecu....then it will ''fly''...well as much as a 50cc bike can that is...
