I have an 86 vt500c. At highway speeds of around 75 I am running around 5500 to 6000 rPm it has the six speed transmission is there a way I can lower the RPMS at higher speeds it would be nice to cruse around 2500 to 3000 the bike is a shaft drive. Is there an aftermarket transmission or what gears would I need to use to get the results I need. 1st 2nd and 3rd gear are great but if I could increase 4th through 6th that would be awesome. Any advice is greatly appriciated
