Have a question. Since I'm doing some serious mods to my quad, Wouldn't be smart to get an Edelbrock carb kit? It's easy to adjust. I don't have to rip the dual carbs out and rejet hoping it right. Now using this carb will it sputter out if I race MX? I'm just not sure of this kit. I'm going with the 690 bore kit. With this setup and what I have done to my quad already with this carb how much hp will I get? Any advice or suggestions would be great! Thanks SSG JACOBS
