Our small local track has blown up averaging about 50 racers a week. we run a stage 1 predator class with the only things being allowed are governor removal, air filter adapter, and header. We specify that replacement springs can be used however they must me 10.8 springs, not 18lbs, no stretching, no shimming. My question is what are the best ways to tech a valve spring to ensure that they are using a 10.8 spring, i realize a red 10.8 will be slightly more. we have a go no go tool for the carb, and can easily check the flywheel to make sure it isn't billet. the main things we want to tech are the springs, head gasket, flywheel, and timing key. Does anyone have any tips on any tools that would help us with this, or any other pointers on what to look for? we have some karts that have all of a sudden gotten alot faster and are pulling away from the field in the past 3 weeks, which is unusual in this class on a small track.
Thanks for the help!
