    Sounds good Kel gotta be a good feeling doing it all yourself! Make sure you ride according to break in procedure for at least the first 500 miles better safe than sorry :chopper:

    Do you remember the breakin procedure required from S&S when the bikes were new? That was 500 miles:yesnod: and there was a specific RPM range to keep it within

    I just figure it can't hurt to be easy on it for a little while no redlining

    Thanks my good man. It was a good feeling for sure. Threw about 100 miles on it last night. The manual states 50 miles under 2500 rpms and then change the oil, I had 50 miles on it by the time I got to the rally. Lol.. then another 500 and change oil. 2500 wasn't possible, it was closer to about 2500 to 3200.. But I did take it easy. Still have a ticking which was the point behind the whole rebuild so I'm actually pist. But everything will work out.

    I chatted with Curtis the other night for a few hours and he pretty much put it the same way the manual did. But he did also warn me of the possible transmission issues due to the added 30 to 45 horses.

    :oldlaugh: I don't like the wide body and never liked the wheel flares on the Rams either, but a pulley change will give me the power without the 2K Insurance bill.
    But to stay on subject, a dyno would tell the real story. 45 hp is almost a 50% gain:willynilly:

    He rebuilt the top end for a reason. Wear would cause it to be down on power from stock. Shouldn’t be hard at all to get an extra 45 horse out of a fresh, upgraded engine over a worn out epa spec engine.

    From what I’ve been seeing, these Big inch twins start dropping power like a brick when they start losing compression. Just a little less than the stock epa spec compression will drop considerable efficiency. Its a lot of fuel to ignite in a big cylinder, if there isn’t enough spark, compression or heat, power will degrade fast.

    30-40 is over reaching in my opinion. The 124 with a 640 cam Crate motor from S&S is 128HP so you can figure it out from there.

    But who knows...anything is possible? Right?

    All I know is what was estimated by S&S using their specs to build it and Curtis did the same in his and said no doubt a minimum of 140 horses to the rear wheel.. so I'm not saying I'm right or you r wrong.. lol.. just what I'm getting..

    when it comes down to it, the only thing that matters is if you are happy with what you got.

    The average S&S hi-compression crate motor, with a 58mm t-body, and a really good tune makes between 138 -140 hp.
    The 585 cammed low compression S&S crate motor makes 127 -132 hp.
    I'm on my 6th one in as many months. Fluffed the heads on the last one, and made 150 hp.
    This one, with my head work, I'm shooting for a tad over 150.
    Your engine is broken in with 100 miles on it.

    With those numbers on the motor, what’s at the rear wheel?

    more importantly, how much can your transmission withstand before it gets launched.
