So i've got an HDJ81 5spd and quite frequently notice my revs are a little high at highway speeds and really kill my mileage for long distances..
i've thought about re-gearing but thats a little $$.
I'm currently running 31" tires and am wondering if anyone has the answer to running a set of 35" tires and not killing the mileage by over working the engine by pushing these tires, but dropping the rpm..
if so, how much would it drop the RPM down by?
at 110kms, my revs are at 3000...if i could do the same speed and cruise at 2500rpm, i would be a happy guy.
Any input helps.
Cheers,
