I have read around on many different forums and most people say the best option is an edelbrock carb, but many say that the stock carb is the best. On my 1998 WR400F, I've got the Keihin FCR, which is a trusty carb. I am looking for something that would be more reliable on longer trips, seeing as the FCR is more for racing (correct me if I'm wrong). Anyway, if anyone would be willing to share their opinions, that would be fantastic. Thank you!
