Ok so I have a 2001 RXX. I have owned it for a little over a month. The p/o either had the top end redone or did it himself not really sure the compression is 120 both sides. From what he said he broke it in the spring and parked it. I did test it before purchase it was a little sluggish so I started doing research that's how I found this forum. First thing I found out was he was using the wrong oil, and it still had some grey lines on it as well. Since I've owned the ski I have done the following:
Changed every fuel line, the selector,replaced the filter in the water separator verified all check valves are functioning properly.
Rebuilt carbs
Removed and cleaned the oil tank, replaced lines, installed new filter.
Cleaned and reground rave valves (the edges were kind of rough)
Today I took it for a lake test. I think I have the mixture fairly close but I have the following issues.
Vibration from idle to between 2500 and 3k rpm. I looked at the driveshaft there is some movement on the impeller side. The impeller will slide in and out maybe 1/4 to maybe 3/8 of and inch from what I have read on here it sounds like the rubber bumper on the end is gone.
Next issue is there is exhaust leaks where the twin pipes join together. There is no clamp but just O-rings on the inside of each pipe where they couple. My thought is get a silicone coupling like you use for turbo systems and slide it on before joining the pipes. Then put a couple big hose clamps on it.
Next problem is I take on some water at lower speed like in a no wake I'm thinking carbon seal since I need to replace the rubber ends on the shaft I will kill two birds with one stone.
My last issue is coming off WOT some times it will stall if I just drop the rpms maybe 2k to slow down a bit.
This is my main concern I have looked and this is the only issue I haven't found a solution to yet. Please chime in and let me know if I'm going the wrong way on any of my other problems.
Thanks in advance sorry for the long read.
