Ok, so the past couple days I have gone out on the XP after work just to try and enjoy as much of the summer that is left as I can.
I have had 2 issues, one severe and one not so severe.
The first has occurred just after startup and idling out of the no wake zone. Basically I idle fine at about 1400 rpm until I roll into the throttle, once at about 2400 rpm the engine shakes and sputteres, it feels almost exactly like a REV limiter. During the strange behavior I see the RPM on my Trail Tech Tach jumping all alround 1400, 900, 2000, 1700. I am able to release the throttle and bring it back to idle and return to the dock.
I have tried RES and ON on the fuel selector and they have made no difference. Once I go back to the dock, pull the seat scratch my head and put the trailer back in the water it runs great (with one exception, see below). It is almost as though the engine responds to the threat of being put back on the trailer and decides to cooperate.
The second issue has only been noticable since I have started riding in the early evenings. During this time the winds have died down and the water is GLASS smooth, because the water is so smooth I have been doing a lot more part throttle cruising and with no disruptions from waves or reasons to change engine speed I have heard/felt the following. As I am cruising say about 50% throttle the engine sounds like this:
Its a tiny little hiccup, but it is noticeable if I am riding at WOT and carving and jumping it isn't an issue. But when I am just taking it easy at 40mph or so it is disconcerting.
I think these 2 problems are related but I wanted the SDF brain trust to give me their opinion.
