I have back to back weekend trips to the UP coming up and I haven't got much ride time in yet, With all the talk about bad rods on new motor just wondering how many mile everyone has on it with out trouble.
 

Just rolled over 1400km this weekend. Pulls to over 100mph with ease. Saw 170 kph at about 8700 rpm. I got scared and let off.

No issues at all whatsoever. Just ride it and enjoy it.
 
A good friend of mine has a LTX LE with MPI trail turbo (and updated fuel programmer) and the motor blew apart with less than 400mi on it this weekend. Yamaha sounds like they are going to be very good about the whole thing so far.
 
Sitting with 200 miles on mine so far and no problems.
 
i have 1600 miles on mine now. absolutely zero issues. my buddy has 1000 miles zero issues
the people having issues are the ones that drove them with the wrong boost controllers. MPI sent out wrong controllers (they were putting out 10lbs of boost instead of 6)in all of the 2016 sea level turbo kits shipped . this was found out after the fact by an incredible dealer in Mich that actually tests each one after install that probably saved yamaha several motors. luckily there wasnt much snow in early dec. so thank goodness for that
or it is from guys running more boost than Yamaha recommends
If you have the updated boost controller you will be fine. just verify with your dealer you have the correct boost controller and hopefully they installed a boost gauge so you can moniter. if at any time you push over 6 lbs. let off throttle and contact your dealer. but Any dealer that installs a turbo withour a boost guage is foolish.
. dont worry about it just ride it !!!!!!!!!!!!!!!!! its a yamaha. and be preparred cuz it pulls like a freight train
be careful cuz these things wake up after 150 miles and again after 1000 miles.

Ride it now while the heat is on for Yamaha to fix it. They may not be as wiling next season...

And it sure would not hurt to have a backup plan in case the worst happens.
 
About 600 miles on my LTX-LE and no problems.

Had the EABC controller reflashed to the correct program back in December.

Sure seems to come alive after 300 miles or so.
 
I have 570 miles logged so far 2016 new motor with Mpi Turbo. first 400 miles with EABC unplugged, last 270 with EABC reprogrammed. Its a totally different machine with EABC finally puts a smile on my face.
 
I rolled over 3500KM last weekend at the Manitoba TY ride. We had some good and long fast lake runs. I agree it works better with the EABC back on. It also is a way different machine when its very cold out. :)
 
Hey InRBigness, what are you seeing for boost readings. I swear with EABC unplugged I read 5psi on boost and with EBAC I see 6 psi (maybe I just didn't hold it WOT long enough with it unplugged for it to get to 6 psi). Wondering if lengthing my waste gate rod will effect anything given the EBAC is installed (may call MPI and ask). My AFR's are really rich 9's on WOT so not concerned about seeing also riding around 1300-2000 altitude. Haven't gotten my clutching dialed in yet so only a few WOT runs so far (bumping rev limiter bad).
 
Without I got 3.5- the odd 5. With the EABC I am able to get solid 5's on cold days with WOT. The EABC deals with pressure changes in reality, not altitude however they are related. I am at 700' above sea level so any pulls to past 6 will involve a system rolling through or as I found out, a really cold day. I think the EABC over rules the mechanical waste gate if I am correct. My AFR almost never goes into the 9's. It is mostly in the low 10's to 12's. At WOT if I remember its in the high 11's. I will endeavor to take a closer look. Mostly when I am going hard I am looking where I am going or glancing at speed/RPM.

From what I've read online from people with failures. There was a lot that had the updated eabc. Hurricane has proven that some rods are not heat treated properly.

Your absolutely right. I've been higher altitude and -20 c. I've seen well over 6 psi. Design is to control the same hp on thinner air.
