RE: what sprokets do you guys have?
Yup. It's a DID 530 chain. "5" is the linear pitch (length between roller pins) and "30" is the lateral pitch (width) which is 30/80ths or 3/8". So a 520 conversion is the same linear pitch but a 20/80 or 1/4" width and weighs 2 lbs less (on average) than a 530 chain. Weaker, so if you go 520 conversion you move up to the DID 520ERV race chain since it has higher tensile strength to resist premature chain stretch or potential breakage.
I leave my 929RR track bike (retired AMA/AFM race bike) with 15/45 gearing which is best for me since it works at most tracks we run and this built 929 has decent enough power than I can just roll on to keep up with most students at our schools.
As mentioned above, I would stay away from a 14T on a liter bike. Each tooth you drop up front is about 6% more torque to the rear wheel, where each tooth out back is about 2.5% (approx.). So 15/45 is about 11% more torque at the rear wheel, 15/46 would be about 13.5%, and so on.

Think of a 1/4" tool versus a 3/8" tool. The 3/8" will last longer because it's stronger.
So no, the 520 will not last as long, and depending on a LOT of variables each person's results will vary. Personally I don't suggest a 520 conversion unless the bike is ridden hard in the canyons or on the track. For most street riders, just the gearing change while sticking with 530 pitch chain will be the boost they need.
