so, new here, first (second) new to me 03 XP-DI. I love the ski, its totally awesome and runs like a bat out of hell when its running good.. Ive had a few issues though. hope to be able to discuss and get them worked through here..
the ski would normally have a decent holeshot, great midrange, and awesome topend.. it would run about 6850-6900 rpms, Ive been told that is very good.. compression is 150 psi in each cylinder(i believe it had a topend rebuild before i bought it.. ) it runs flawlessly, except for a couple issues which have popped up in the past couple weeks.
- water regulator.. I replaced the diaphragm, and the ski suddenly would only turn a max of 6700-6750 rpms.. and it was sluggish on the bottom end.. the spring nside is so strong, i believe it is keeping the valve open. Ive ordered a new spring, and hope that will help solve the issue. The housing has the non-adjustable cap on it, and ive been seeing where others have adjusted thiers to suit thier tunes.. my main question is, "at what rpms should the valve close? " , or, better yet, how to properly get this setting matched up with the rave valve settings?
- Fuel pump. my dang fuel pump went out.. so i found a replacement on ebay, this could possibly be some of the sluggishness and rpm issues as awell, as it went out as soon as i repaired the water regulator.. strange, coincidence i think.. i also tried to use an automotive filter on the line, but i went ahead and paid the good money for a seadoo assembly.. i think overall for the life of my ownership, this will be a better choice..
- Oil tank.. for some strange reason, the ski seems to be using a lot of oil. like a tank to every two tanks of gas.. this is not normal is it? I am using seadoo xp-sII synthetic.. one of the issues I have here also, is that the oil line will not remain primed above the filter.. I usually prime it, fill up the filter, fill up the line before every time i go out, and after an hour or two, there is air above the filter.. i have ran it like this for an hour or so unknowingly, and it seems that oil is still supplying to the filter, and below the filter between the pump, its always full.. so im not sure whats going on there.. i have ordered a new separator and check valve, and that might help, but i dont think that will solve the issue..
- bilge pump.. how can i check if this is working? is there a float switch somewhere? or is this always on? its still stock, i dont have a problem with water in the hull, unless i take a big wave, but its one more concern that i should limit..
other than that, when the ski is running, its a hell of a lot of fun.. i can carve up the lake like a mad man, jump waves, and accelerate and hit top speed pretty quickly, my speedo is saying 60-62, but i know that is false.. my goals with it are to create a midrange monster that has good holeshot with decent top speed.. the only thing that gets me, is keeping it hooked up in rough water.. I was thinking about an R&D grate, but I think I will wait until im ready to do an impeller.. Ive ordered an Adjust-A-Thrust, so im hoping to get that installed and tuned as soon as i get all repairs made and get the ski worked out..
sorry fo rthe long post, just thought I would get it all over with in one shot!!
