Im looking at buying a Zepplin seat from a local guy in town. He said it worked fine for 3k miles, and he hated it the entire time. It quit working on his last trip, and he finally said screw it and bought a different seat. He said he called the dealer, and they didnt seem concerned like it was a common problem and easy fix. Has anyone else had this problem or heard of it? The pump doesnt work at all he said. Just kind of wondering if it might be an easy fix for a poor do-it-yourselfer like myself. Thanks in advance.
