660 questions

Ok, letís start by I bought the dreaded 2001 660 for my daughters and me. Gone through starter clutch and unplugging the park brake and basic tune up. What else do I need to worry about. Mine has 11:1 stage 2 cam Yoshi pipe and GYT clutch pro filter kit daughters have M10100 piston stage 1 cam, new clutch sets all have gecko tires. Question daughters are scary fast on mine but I weigh 240 vs 130 and it falls off cam on long hills. So if change to Skat Trak 8 will this help me keep rpms up on long pulls. Transmissions have been changed so do I still need to worry about 2nd gear.
