    '04 GP1300R compression 90-80-100 on autozone tool, 100-90-110 on snap on tool?

    Is it time for the front 2 piston to be redone? I just had the rear piston done 10 hours ago. and my ski cuts in and out @ WOT. ski has 115 hours. front and middle piston never been serviced. im premix, all my plugs are dry black with oily thread.

    well first thing's first. Only trust the snap on gauge. So basically the motor is getting a little tired since the service limit for compression is 91 psi. So it sounds like a set of rings and a hone would do it some good.

    Can't just replace the piston and rings if the wAlls aren't dAmaged and would doing wheelie on jet ski cause this problem ?
