I have followed this forum for quite some time and through searches, I've been able to get answers to all of my ZX-14 related questions. I have recently purchased a fairly new 2017 ZX-14R. I already own a 2008 ZX14 that is a work in progress. The 2017 has 3640 miles on it and will be under factory warranty until Mid March. The previous owner had to sell it quickly because of financial problems and I was able to get it whopping $5K. The bike had been sitting for a couple of months when I bought it and the battery was completely dead. The previous owner had also low-sided the bike so it has some rash on the left upper fairing and on the fins. All of this made me not believe the financial problems story as much but I decided to gamble anyway knowing that there may be something wrong with the bike past what he was telling me. The bike itself has a Dual Brock's CT Full System and the ECU was flashed by Brock's with the along with the PCV Mapping. This concerns me because i have read that warranty could be voided because of the flash. I am even more concerned because after I was able to get the bike started there was an intermittent rattle coming from the motor. After blipping the throttle the rattle goes away momentarily and it returns. Blipping the throttle again makes it go away again.
For the experts I'd like to know what that could be and if it is an expensive fix. I blew the motor on my ZX-11 years ago and know what that looks and sounds like and this doesn't seem to be that. My other concern is will dealership take bike in for warranty work that has rash on it. (plan to replace plastics soon). I'm hoping that I don't get burned on this deal so I have my fingers crossed!!!! Thank you guys in advance for any insight, information, or guidance you may be able to provide. I have added pics of my bikes and below is a link to the YouTube page of the Gen 2 running with the rattle. Please forgive my horrible voice over.
