Default Gas Cap Question 08SG

When you guys tighten your gas caps do you turn them till they tighten and click (slip), or stop before they click?
I know it is a pressurized system and the cap needs to be tight, but do you need to turn it till it slips to get the proper seal on the system?

Turn it till it clicks a few times. That way you know you have the proper seal. It will not let you over tighten.

+1 what he said ^. Otherwise when it runs the engine diagnostic when you go to start it if it's not sealed fully it most likely will throw a check engine light code.

Well it may be a pressurized system, but I ran my 08 SG a full tank run without a gas cap and no codes or running issues.Yea I left it on top of the pump.

This thread is right up there with:
  • which bike should I buy?
  • should I use synthetic oil?
    how much air should I put in my tires?


......and last but not least:
  • do these chaps make my a$$ look fat?

"clicker" gas caps have been on cars and trucks for the last umpteen years.

I know it is a pressurized system
Uh. NOPE. If it weren't vented it wouldn't deliver fuel. Where does this 'pressure' come from if it's vented?
