So I have about 42k miles on my 16' RR and of course the front servo flapper thing is leaking. Has been for a while and would quite up once the bike got warm but its gotten to a point of annoyance. I have a set of akra headers I'm gonna install cause they were MUCH cheaper than replacing the factory pipes. My question is, since my mileage is gonna sky rocket here in the next year and since I have the headers off. Would it be worth just throwing a new set of 02 sensors on? Clean the old ones? Just put the old ones back in? My automotive side says put the old ones back in. My motorcycle side says replace. I don't know how long these 02 sensors last so I'd hate to have them crap out and leave me stranded.
