    Can someone tell me what cams I've got in my 2008 Nightster, all I have come up with on the net from bike reviews is that they are high performance "w" grind but no specs...I'm looking at a possible stage II upgrade to bolt in cams but without knowing what I'm upgrading I'm stumped.
    Stage 1 so far SE pro heavy breather, V&H sideshots, V&H Fuelpak
    Any recommendations for ignition modules compatible with the 1200N would be appreciated...:naughty

    My tech has told me the nightster rev limiter kicks in at about 7000rpm (feels less) same as the XR 1200, 500rpm more should be enough or will I need more taking into account I'll be fitting new cams.
    I knew I should have gone with the PC III...:(

    Don't know about that 7K rev limit, but I wouldn't spin any harley engine much over 5500-6000 if that. Engine longevity is directly related to the way it is ridden.

    I told him that my rev limiter was kicking in at about 5500rpm and I wanted to up it to 6000rpm, he told me the nightster rev limiter is set at 7000rpm, when I questioned this he showed me the rev counter on an XR and sure enough red line is between 7k - 9k, say's the engines are the same...
    I've now found out that the V&H fuelpak will not allow you to change the rev limiter, it only adds or decreases fuel...:coffee

    And that was the head HD mechanic at my dealership that told me that...:wall

    That's why you come here to find out the truth. Hobbit will give you the straight scoop that you can trust.

    was it the "head mechanic"?, or the "Service M:55:nager" Service manager are about as honest as a lawyer IMO

    That's the one "Service M:devilnager...
    So what about a Screamin' Eagle Performance Ignition System, or is there an ECM flash fix to bypass the rev limiter...I only want another 500rpm or so...:51:

    I believe the stage one download brings the rev limiter up to 6200......I think think.:D or you could put on a SERT or a thunder max. A higher rev limit isn't needed for IMO.

    In low gears since the stage one mods the bike lifts off on acceleration then bogs when it reaches the limiter, just a whisker from hitting the sweet spot, and the boltin XL cams work better at higher revs also, so just a tad higher with the rev's and I'll have the low/mid/high range bases all covered...:yahoo
