    Default super trapp internal series for Harley SE120R motor

    Hi All,

    Am looking to drop a Harley bolt on SE 120 r engine into my 2011 street glide ( currently running 103). I'm currently running the internal series slippons for street glides. . . will these still be appropriate for use with the 120R engine? If it is still good to use with the set up - what would be the correct number of discs to use to optimise midrange torque (as opposed to topend horsepower) and keep the engine noise to a manageable level?? I'll dyno after engine install also.

    Ideas and recommendations would be very helpful. Thanks in advance, Hamish

    We have NOT done any testing of the internal disc series slip-ons on a SE120R. For tuning purposes we would suggest starting out with your current set up on the 103" and add 2-3 discs per side to accomodate the additional flow of the 120".
