I'm taking some parts off my bike for paint, and one of them is the gas cap. Couple questions:
[ol][*]Will leaving it off for a couple days damage anything as far as fuel quality/air pressure/etc?[*]How long can I leave it off without causing any harm?[*]What do you suggest covering it with? [/ol]
I didn't know if it would do anything other than the gas evaporating more quickly because of air contact/less pressure? I'm planning on sealing it up tight with plastic and duct tape.

Thoughts?

 

You're definitely going to have gas evaporate as soon as you have the tank open, so my advice is to ride it till it's almost empty or drain it if you can... also, you can just put some plastic over the tank and use painters tape to go all around the opening and try to get it as air tight as possible to keep it as sealed... that'll keep anything from falling in or getting any dirt or dust in the tank... that could be aweful for the engine

 

That's what I did immediately. I didn't want any debri or dust gathering up or getting into the tank. I cut a sheet of plastic to overlap the hole, then duct-taped the crap out of it sealing it down and filling the whole cap recession. On top of that, I keep that covered with a moto cover at all times.

Is that my only worry then? Debris and losing money on gas because of evap?

 

+1 to what VP said.. you will be fine.. but duct tape on paint.. ehhh

 

Yeah, Ididn't duct tape the paint on the "visible" tank. Only duct tape inside the well the cap covers.

 

o alright

 

if it leaves any adhesive you can definitely just use goo gone to get it off... that's cool though if you've got it covered up really well you should be okay.

 

just stuff a sock in there and ride the hell out of it.
