    Engine Alighnment

    HELP... GP1300R - I have a vibration I'm trying to chase down and want to make sure the engine is true, it looks straight from everything I can tell, but whats the best way to measure that the engine is straight?

    ****EDIT***
    PS: Anyone ever had a Harmonic Ballancer/Flywheel come loose? (also thinking vibration), I'd imagine it would make a hell of a racket (noise) if it came loose, so don't think that is my vibration issue).

    thanks in advance.
    Damo.

    Have you had the motor out before?
    Have you checked the pump bearings yet?
    Have you checked the rubber dampner/coupler?

    Yes, Motor came out to put a 3 deg timing key in, Engine mounts were marked and put into the same position as when they came out. Dampner/Coupler seems to look fine.

    Brand new pump bearings (just upgraded to new 05 pump and dynafly). pump seems to be pressed on correctly.

    PS: Also only making 6500rpm... suspect partly due to vibration issue.

    Mods =
    - 3 deg Timing Key
    - Delta VForce II Reeds
    - Wave eater Power Valve Couplers
    - Wave eater Power Valve clips
    - D Plate and Temp sensor chip
    - GP1300R ONE PIECE Flame Arrestor
    - R&D Ride Plate (machined)
    - R&D 1200 Intake grate
    - Pump plug kit
    - 05 pump kit
    - 14/24 Dynafly (yes too high but all I had at themoment)
    - Pump Tunnel re-enforcement.
    - EFI controller

    Was the timing key installed in the proper direction?

    Did you use a small straight edge on the drive couplers on all sides. You probably have the engine correct fwd to aft via the marks but side to side is huge. A cherry picker is a big help. Recheck after tightening. It might take a couple of loosens and tightens to "get her done".
