Well, my original return was a wide pedal crank kit. I ordered one without the conversion. Once received, I realized I needed the conversion kit. They don't sell just the conversion kit. So I ordered another complete crank kit with conversion, and wanted to return the first one!
But they require a return authorization prior to sending an item back. I attempted to call several times, but all I get was elevator music, and no voice mail.
Today, I finally got through to a real person, and was denied a return because I received the items on 6/16/15, and today is 7/9/15.
I opened a paypal dispute, and I believe paypal has my back!
So to answer your question....
I originally wanted to return a wide crank kit without conversion, but NOW Im going to return everything I have purchased from them more recently! This includes the crank kit, rubber mounts, chain tensioner, expansion chamber, another expansion chamber, X-port exhaust port, velocity stack, Air intake manifold, Stainless screw set, etc.
And no more anything from gasbike.net
Here is a thread detailing my experience with them, as well as other forum members that experienced poor customer service from gasbike.net:
