Potential Riva powerfilter issue
Just got in from a 60+ mile offshore ride and I am washing the engine compartment and find the k&n filter on the Riva powerfilter sitting on the gas tank. It looks like impact from riding off shore caused the whole filter to slide right off. Those who have the powerfilter will notice that the hose clamp that goes around the k&n filter cannot be tightened fully because doing so deforms the powerfilter. Please guys, if you run a powerfilter keep a close eye on it. This could be very dangerous!
It looks like I dodged a bullet because the ski ran great on the hose but I'm not taking any chances. I'm going to pull the plugs and I am also going to fog the engine. Anything in perticular I need to look for?

I knew there was a reason why I didn't buy that thing! can you put a sleeve inside the pipe to make the plastic more rigid? just a thought

is this because your filter moved or has your fuel tank moving around. do you have a pic.

Considering how many of these are in use & this being the first issue I've ever heard, it's not something to panic about. I've had one in my SHO for over 200 hours with lots of pounding from offshore riding without issue. Mike, I wouldn't worry that you did any damage. The opening of that tube is real high in the hull, & the cone element is really just a flame arrestor. If you're not using the pre-filter sock, it's actually not filtering anything at all. Using a second clamp might help if you're worried about it happening again, or you could use a t-bolt clamp with a fatter band. You could also horizontally scuff the end of the plastic tube with a wire brush or some course sand paper to add some grip when the clamp is tightened down.

What about a little silicone sealant before you clamp it...

Anyways, pics tomorrow.
