UPDATE: You dont have to remove the coil packs, engine cover brackets or the cam sensor to do this. Takes about 5 minutes off the bill. :)
Here is short video I made on the process of visually inspecting your Yamaha 1.8 liter timing chain. The process only takes about 15 minutes to do. As most of you know, the 2014 and 2015 SVHO skis have had some timing chains breaking. If your ski is currently operable, I suggest periodically inspecting the timing chain. The timing chains aren't generally snapping immediately. They are breaking a link or two before going into complete failure. This inspection process may give you the ability to catch it in advance.
Note: You don't actually have to remove the coils.
