Anything done to the engine performance-wise? 5000 sounds very high, but it really depends on your ratio. We've built clutches for the 250s and 450s through a jackshaft, but the engagement was in the low to mid 3,000 rpms. ----- Thanks and God bless, Brian Carlson Carlson Racing Engines Vector Cutz www.CarlsonMotorsports.com Carlson Motorsports on Facebook 32 years of service to the karting industry Linden, IN 765-339-4407 bcarlson@CarlsonMotorsports.com
