Need Help on Waverunner VX Air Intake Restrictor Removal

I have a 2014 VX and am having a very hard time removing the air intake Ribbon/Restrictor/Flame Arrestor. I have pried around the edges with a standard screw driver as per some of the Youtube vids but its really not doing that much. After one hour I gave up. I'm now considering removing the intake manifold to gain better access to it and drilling it out, but I don't know how to remove the intake manifold. I've removed the fuel rod and the 2 manifold bolts on the underneath side, but I just can't get a tool on the 2 hose clamps per cylinder that seem to be holding the manifold on. Do I need some kind of special tool? Also, it I appears that the lower of the 2 hose clamps is only accessible from underneath. How the heck do you reach it?

Any help would be greatly appreciated,

Rick

I finally was able to remove the intake manifold and drill out the flame arrestor/ribbon. To get the manifold off, I needed an open-ended 7/32 wrench to remove the hose clamps on the top and a 7/32 socket for the bottom clamps, then manifold came right off. In the end, it was such a pain to remove the flame arrestor that I don't think I would do it again. It's certainly not as easy as the youtube videos show. You can't just pry it out (I tried that for over 2 hours without much progress). I've read that the gains aren't much without the ribbon so, I'm not expecting much. I use the ski for long distance touring and I'm trying to optimize mpg rather than top-end speed or quickness out of the hole. We'll see if it helps. I'm also adding an air filter on the intake throttle body and am reworking the old air box to serve as an additional storage compartment. The next and probably last mod will be a solas prop. I've read mixed reviews on changing the ride plate to somthing like Riva's.

Hope this helps someone considering removing the ribbon on a VX.

Glad you figured it out. I've never worked on one, so I couldn't have helped. Ride plate will stabilize and add a bit to top speed. More of a handling addition. You will get the most bang for your buck with a Solas impeller, and make sure the clearance is at the bottom of the tolerance. You could even deburr the pump to get rid of any sharp edges and roughness that the water runs into and across.
