FZR SVHO 2014 : Chain Broke Problem
Heard that lots of people faced this issue. Now, it's my turn, my 2 FZRs faced the same problem !
One FZR @ 15 hrs and another FZR @ 6 hrs which damaged vales and top of pistons as shown in
the pics. Both are stock.
Any suggestion how to solve this problem ? How to upgrade the chain ? Have aftermarket chain ?
Thank you for your advice !

Maybe buy one for the older model, or cyrogenic freeze treat chain.....it a shame you spend so much money for that to happen to yoir investment

Wow both of them??? What were the build dates on each of the motors (date on valve cover). I do not know of any stronger chains produced either at this time. I have been told by more than one reputable source that all the chains are being made from same supplier for Yamaha pwc division

the small dings in the pistons wont hurt anything, but thats the least of youre problems, 1st, whats the piece stuck under the oil pump pick up ??? 2nd, replacing all the valves, theres a good chance all you will have to do it lightly lap the new valves in and reassemble the head, valve lash should fall right into spec. 3rd, look to see if the cam may have seized in the head, ive seen it happen, we had one seize enough to just jump the timing about 90 degrees, bent all the exhaust valves 4th, make sure it didnt damage the teeth on the crank or break the chain guide support, if so, ether or youre screwed, a good welder can repair the block, but the crank will be a paper weight. good luck!!!

I wouldn't even let the dealer rebuild.. Better replace that full longblock with something fresh out of the crate.

Wonder what's going to happen to the first guy to get a timing chain snap fresh out of warranty? Spent 13k+ for a ski to have a potential chain snap out of warranty won't be pretty to fix out of pocket for the typical guy expecting Yamaha dependability.

I know only one svho here in Italy.
and he broke his chain at 44 hour. ski is stock + riva gen 2 IC, SCOM, ribbon delete, new prop.
yamaha cover all under warranty.
I hope yamaha has solved this issue....
