  • Coils/Stator 1999-2004/2005-2007

    Hi,
    I have a 1999 roadstar 1600XV.
    I'm looking to upgade my stator (21 amps) to the 2005-2007 stator (32amps). I understand the upgrade is bolt on. I also understand you should go with OEM only on these components who I found Partzilla cheapest for online so far for OEM parts. Any other recommendations? So for anyone else doing this upgrade her are the OEM part numbers, and YES, you need to upgrade your voltage reg when doing the stator assembly. Don't let anyone else tell you different.

    1999-2004 OEM part numbers
    stator # 4WM-81410-01-00
    Rectifier # 5BN-81960-00-00

    2005-2007
    stator - 5VN-81450-00-00
    Rectifier- 5VN-81960-00-00

    Any other suggestions or comments? What about coils? My bike keeps eating coils, i have a set of Dyna coils but don't like the mounting mods as well as I don't like the way the connections sit on them.... are they that much better? I could relocate but prefer to keep them where they are and not have to modify wiring etc....

    i hope this helps others as well.

    I think you have some bad info on the stator output numbers you posted. Also Before I put a new set of coils on the bike I would find out why you are burning up coils. What exactly do you mean when you say "eating coils"??? That is a very unusual issue. Do you still have the resistors in the spark plug cap? Or did someone bypass them with a pc of 2ga copper cable??? Are your plugs gaped correctly?

      +1 on the cap resistors. People wonder why the bike has resistor coils and plugs both. Take a look at the coil resistance. Easy to hammer low resistance coils. Might not be the issue, but worth looking at. I’ve heard of at least 3 99 owners complaining of “eating coils”. Never heard of it with any other year. I have to wonder if there is something being missed in diagnosis.


      Wherever you go in life, ride there if at all possible.

        I’ve gotten the output numbers off previous roadstar forums- I’ll confirm with yamah specs Tuesday. I’ve put in new plugs with proper gap, checked resistance of coils, wiring, and cap resistors... all stock and within spec, I’ve replaced all components with stock new as a precaution (electronics can fail intermittently when they get hot) - doesn’t leave much to go over left
