Hi I have a Gp800R and it has been bogging down on the get-up and it can only hit 6000 rpm on a full tank. top speed is 43mph when I am close to empty it will jump up to 48mph both tested with GPS but both Speed runs bog down when it hits top speed. I did a compression test and it was really strange 110-120 on the front and 150-160 on the back but both go to 160 when I pour a bit of oil in it. I think it could be the piston rings because it rattles and knock like crazy. but it could also be the power valve I don't know that's just what I was told by my friend. I got the ski for free from a neighbor but I don't have any history of what they've done everything seems to be stock it was an older couple. any help would be great.
