FX SVHO loose exhaust bolts.
Just a heads up for everyone, even though my problem might be an isolated one... With less than ten hours on the ski I found the six bolts fastening the flange on the exhaust manifold to the watercooled exhaust loose resulting in the spraying of water into the hull. It took nearly a full turn for the bolts to start taking up, but it's not possible to correctly torque them in situ due to accessibility issues. When the bolts were nipped up it was still weeping at idle on the hose, probably due to passage of higher pressure water at WOT compromising the gasket. Clamps at the other end of exhaust on flexible coupling to water box were also loose.
These items were not touched during the hull repaint, nonetheless the shop (Excite Motorsports) got straight onto it. The service manager came in on a Sunday morning (when they are normally closed) to take the ski off my hands as it was convenient for me, and had it fixed in time for me to collect on the way back from work a few days later. They took off the exhaust manifold, changed the offending gasket and re torqued the header to manifold, then refitted the manifold with a new gasket as well, all gratis...
They contacted Yamaha who have conceded it's likely to be an assembly line issue. That doesn't mean that it has happened to anyone else but I thought I'd mention it in case there is someone getting unexplained water in the hull. Mine would weep on the hose at idle and start spraying by 2000 rpm. Might be a good practice to periodically lift the seat and look for anything untoward when flushing...

Lol! There is always something loose with these new svho.
Mine had the exhaust coupler to water box loose. Also the charge pipe going to the intercooler from the blower.
I hope the fly wheel isn't loose too :/

Mine was the charge hose. The clamp was completely loose on the throttle body.

My FZR spit out the divider out of the intercooler within 15 minutes. If the flywheel comes off so will the ski off the trailer. I'll park it on the dealer's lot. What's with Yamaha this year? My 2013 FZS has been flawless.
