EFE fuel cap

[Dezmeister]

May sound like a Dumb question bud does anyone know if the tank vents thru the key slot.as the cap whistles like a kettle once ive been out.ps bikes turboed.any remedies or cap replacements appreciated.

Yes it vents through the cap but not actually via the key bit.

From memory:

Under the small hole under the flip up lid of the cap; there is a rubber mushroom shaped bit acting as the actual vent

That might be slightly disformed.

I had a similar problem years back when I was young and even more stupid than I am today, with my old efe fuel cap. At high revs the motor was bogging down so dopey here, to test my vent blockage theory decides to remove the cap flat out on a long bumpy straight local to where I lived.

I was rewarded for my stupidity ( as anybody whose ridden these with standard running gear will testify) with an almighty tank slapper followed by a good head to foot dousing of petrol, when I finally got the fucker stopped I spent the next twenty minutes looking through the undergrowth for the offending cap. Lesson learned!
