when i built mine i had it in mind that i would be riding longer distances,definetly look into a aftermarket gas tank i went all in with the clark tank 5.5 gallons nothing like almost never having to worry about gas when your out there my favorite sand hills and trails are a 4 mile ride there and another 4 back and i usually run out of gas before the shee does, my engine is a 421 cheetah with powervalves, the powervalves are great when your in the trails you dont have to shift as much when your up and down in speed, any nice aftermarket shock with do just great on the trials, i run custom noss head 20cc domes +4 timing, oh and crank is 4 mill i love the set up for the trials around here
