can i drain the 'float' screws if i dont turn off the tank based petcock. Or should I turn off the tank petcock first..

I need to drain the tank too.

I want to remove teh float bowl thinge so i can change teh jets.

I am working on the bike as i am doing typing.

Why do you need to drain the tank?
turn it off at the bottom of the tank, then drain the carb bowls... i would leave the gas in there unless it was bad

If you disconnect the tank you can drain the carbs.

[TheGoodGuy]

okay so i do have to turn of tank petcock.

blah i need a 2nd hand.

[cheesy]

plus if your gas is nasty you dont want to push it down into the carbs

You can drain the float bowls without turning off the tank petcock as long as you're in the ON or REServe postions.  If you turn the petcock to PRIme, then the tank will drain slowly, but  completely.
