I am looking at getting my first Monster. Im looking for a S4RS, preferably with a Termignoni full system already installed. BIke has 5500 miles. My question is this, what do have to be concerned with on this particular bike. To my understanding from reading your forums even thouhg the Termi systems come with a ECU you still need to recalibrate the throttlebodies due to the fact that the system does away with the o2 snesor. If the previous owner of this bike did not recalibrate what possible engine damage am I looking at and is there a way to test for it before buying? The dealer that has the bike now says it runs great, although they all say that dont they. THanks in advance for any help you can give.
