Recently threw a rod in one of my two RN19s and I was wondering if I could get some insight. I have an entire r1 sitting in my garage excluding an engine and that stings for sure. I found a 2007 FZ1 engine on Craigslist for about $500 with ~20,000 miles on it and it is in pretty good condition. I was wondering since it is also a 4C8 engine. If the swap would be seamless. I always heard that the old fazers were "detuned", but what exactly does that consist of? Is it mostly electronic? Thanks for the help in advance.
