Kind of an interesting zombie thread. So a guy buys a new NT and has major issues at 2200 miles and 5 months and it wasnt fixed under warrenty? Did I get that right? It does sound like the engine ingested something.....no matter....If I bought a new bike and it had major issues that kept it off the road for months, I would be on the phone to Honda.....
These kinds of issues on 2010 and after Hondas (and indeed well before) are very very rare..... especially when they are isolated....not like the 2014 Subaru Oil ring problem at all.
