Title: Venting the Kymco locking gas cap
Post by: CROSSBOLT on April 29, 2024, 11:16:24 PM
Solved my problem with sudden death and slowly  dying scooter engines. Modern setups have a vacuum operated vent valve that sticks shut.

Remove these two screws and have a good grip on this cover and the two catches because they are spring loaded!

Diassemble the parts being very careful the sequence. Place them in a similar, organized fashion for reassembly.

Put it back together!
The key goes into the slot lined up with tiny triangle at the top of the black cover held on with three tiny screws. The key opens the cap with a quarter turn to the right. Make sure this action works like this after you reassemble!

I'm getting old. Any one have an extra black spring? It's in the shop somewhere...

Yeah I've got plenty Karl, behind the garden equipment in my garage somewhere!

Nice work Karl!

I think it was you who had me drilling a hole in my LIKE's gas cap years ago - when it was doing that imitation of a bucking bronco. (as the TPS failed)
Couldn't hurt!

Man - I learned more about taking my LIKE apart and putting it back together in those few weeks of fairly new ownership when that TPS went south!! Still have some "nothing the matter with these orig. parts" in my tool drawers as the forum recommendations rolled in! ! (fuel pump, coil, plug cap, plugs, plug wire, injector, etc.)

Then you loaned me your KYMCO diag. tool! And we got it solved.

There was a request for this from an owner of a 2011 DT300i. I knew it would be quicker to do the photos than to find the original post.

Yes, Neil, I have the same spot in my shop! Har, har!

Stig, that was the eyeopener to how disinterested dealers and their techs were in learning their product.

I put a non locking cap on my super 8 150x  from a honda nc700x. Fits perfectly.

FOUND THE SPRING! It is back in the gas cap!

Karl lost that spring in 1987. It was a Tuesday.
This man never gives up!
