    Gp1300 rough idle and low top speed.

    I did the d-plate and chip, power valve keepers, and some other maintenance to this 1300 early this year. It seems the idle is too low and top speed was only in the low 50's. Plugs show a good color, compression is good, no fault codes, pv motor cycling,anybody have any ideas??

    Thought I'd update this. It got a bit worse about the idle. This time I could feel something not right with the throttle. Turns out the cable was frayed and coming apart right where it splits into 2. All fixed now!

    Did the low idle increase to what it should be after replacing the cable?

    Yes, idle sounds much better now. It was low and sounded like it was missing before.
