Hi Mark,
No need to change anything. LiFePO4 batteries's max-charge voltage is actually slightly higher than lead-acid, so using it with factory RR will result in slight undercharging. I've been using small 4-cell battery on my race bike for past 3-years. Still working just fine.
Word of caution, many of these batteries do not have over-discharge protection, so leaving lights on for more than 5-10min after stopping will damage them.
