Not unless your gas cap is connected to your 5th gear...
...
We need you to study your symptoms... instead of just firing off random possible solutions...
Also,.. some general info would help...
Where are you located?...
Are you male or female?...
Do you have any mechanical experience?...
What year is your bike,.. and how many miles?...
What mods does the bike have?...
...and could you post us a pic of your bike so we can get an idea of it's overall state of modification and condition?...
Until you give us some details... you'll just be chasing your tail...
Which is what's been going on here for 3 pages...
