Water box failure 2004 GP1300R
Just found (well hopefully) the problem on my ski where it would not pull past 1/2 throttle and would top out at 50. Well it would pull past this for say 2 seconds but would then bog down to about 50 MPH.
2004 GP 1300R with all the normal sort of mods, VF3, 3 deg key, heads, 2005+ pump, EFI controller D plate, etc etc.
Well as there were no error codes assumed that the problem was mechanical so checked compression and pulled the heads which were all good. So now the brain had to think a bit so pulled the exhaust and was wondering if it was a blocked exhaust. But as the ski had a D plate I could think what it could be. So I put my hand in the water box to check it and turn my hand uck black with 200 hours worth of oily carbon. From the pic you will see what I found.
Has anyone seen this problem before?
Looks like it was blocking the water box once the exhaust preasure got up and the lump of tubing worked its way to the outlet in the water box.
The ski gets ridden in rough coastal waters, so has a hard life.
One good thing is that I've had the Jetworks mod on for approx 150 hours and 4 years so the water box doesn't get flushed from salt water and no visable bad corrosion.
