Moving down the highway, I often look for that 6th gear my 02FLHT doesn’t have. Not that I'm screaming, but it would be nice to just lower the RPM a tad. A quick back of the envelope check looks like I'd like a 15% reduction in the overall gear ratio, bringing 5th to something like 2.73. Would the 15% reduction on 1st hurt? I spend very little time in stop & go traffic, and this change would bring first down to 8.75, about mid way between the original 10.11 and 6.96 1st & 2nd. Does anyone know what options, if any are available to achieve this, or do I just have to part with the bucks and get a 6 speed?
