I have a set of bender pipes coming for my Viper S. Does anyone know how to set up the sled for reliability. What head should I get, or should I just get the head mod done? I'm thinking an aftermarket head would be better in the long run. What jets should I use? Is there a carb adjustment needed to run the pipes? I heard something about moving a clip to adjust idle mixture, or is it for something els? The stock clutch works very good now. Power is alway's there, no backshift problem. Will I have to do clutch work to get optimum power? If so, what do you guy's reccomend? I want to go as fast as possible in a 1/4 mile and still have a good backshift. I was considering sending the primary clutch to a pro, or is this something I can do myself? Engine work is no problem. Carbs seem pretty straight forward. But I have never taken apart a primary clutch. Any advise is appreciated. Thanks.
