    Correct me if I'm wrong but the HD 98 inch kit is a bore kit only. If you want low end torque you need to stroke it not bore it. That means tear it all down an put some wheels in it to get longer than the 4 inch stroke that you have now (and I'm not talking genetics).

    If you want to do it right. Take the 88cy to a 107 cu.
    Then you will never ask for any more power.:gah:

    He needs to build more cylinder pressure to build torque he can do as you said put bigger arms in it or put more cubes in it with a dome pistons and some port work . My choice would be big bore short stroke less mass quicker rpm . Long stroke small bore don't likee . But that's just my way of thinking lots of ways to skin a cat.

    From my understanding going from a 88cu to a 107 makes it a stroker motor.
    It build plenty of torque.
    Got a buddy that loved building them.
    He liked Axtell cylinders and pistons.
    Forgot where it was, I think it was in Florida he sent the cases and had them and the new crank done.

    88 isnt going to 107 no way no how without either
    flywheel change or boring the cases. 98 is about it without having to get
    inside the cases.

    Good Gain, I would go 95 as it's simple, pistons flat top, youll get a nice bump
    everywhere.. Want more lower RPM power, change the cam..

    BTW when you are at 60 and need to rock n roll, push that little lever by your
    toe down. Then twist the throttle...

    When life passes you by,,,, downshift

    Right on Brotha.....:cool: I guess I am so used to not having to downshift for power..(Sportster, which I ride a lot yet!!!!:D) I would love to be at 60 and have the balls to pass without shifting. Just a sickness that I have I guess. Imaging buidling good pressure at 60mph then downshifting??? WOW... Wait, you don't have to imagine that...:cool:

    There's no substitute for size - might as well up the cubes and get it over with.

    If power is all you want.:gah:

    If you want to go to a 107 yer gonna have to change flywheels, you know that.
    Were talkin about Power, not just playing

    I've seen a 107 hold up pretty dang good if it was broke in right.
    It will use fuel when you git on it too.
    And you will have to beef up about everything on yer bike too. Brakes, clutch and all.
    And if you ride it like yer sporty, it will burn the tires off the bike.

    This build will be expensive also.

    Power seems to be the only factor.
    It will run better than Johnny's sporster too.

    I suspect that once that I am able to bring in some timing on this monster that it will closer to satisfactory. Just bracing myself I guess for the expense.. Still, no major upgrades have been done to my bike.:cool:

    point being 95 CUI isn't the complete limiting factor.

    However unless you are running a new cam
    with timing like the 6H don't expect much in the way
    of 2500 RPM power.

    Red Shift .557 and planning on using the +4 key in that if needed...

    you still need compression, head flow, intake matched, bigger carb, and bigger pistons..

    Start getting the parts together for a winter build,

    1) heater
    2) heater
    3) another heater
    4) parts
    5) gloves
    6) heater

    I don't see a lot of difference in the 557 and the TW37 in respect to the cam timing, specifically intake open/close which is an indicator of when you're going to start to build torque...I could/likely be wrong but you'd need to raise compression to give you more bottom torque with both of those cams and the intake on the 37 opens and closes earlier than the .557...I think to get the torque down low where you want it a TW21 or26 or Crane 300 would be better than the 2 you're looking at although they aren't new exotic cams,they do work well for bottom end torque in 88"- 98" engines...
