Hey, just looking at doing a sprocket swap on a 99 Magna 750 for a friend. She bought it and the guy geared it for more acceleration, but it is getting horrible mileage now since she rides in out of town a lot. Got a new x ring chain for it, but I see that JT and Sunstar both make a decent selection of sprockets for it. Anyone ever have a bad experience with either? Looks like JT makes a few more options, but I thought Id see who here had some experiences with them on bigger bikes.
