It does not go into 5th unless I am going down hill or on a very flat road abouve 60,I do plan on some gears that are better suited for the motor but I was suprised its drinking gas like it is just running around town. It might not be really using much more since the speedo is not correct but is seems like it and I cant get the speedo corrected untill I get the gears I want to use. I was wondering if a cam with a different profile like a RV grind would help it be more effficient now that the motor is not spinning as fast as it was.
