Most riders of the M8's dont realize the power thats available in keeping the 114". I had planned to go big bore since I bought me 2022 street glide special new in December. However, I did a stage 2 kit zippers kit on my stock 114" motor. Now I had a great tuner and bought the right parts to make a great combination. I made 128hp/129tq to wheels from a 114" for about 4600$ Parts list as follows. Zippers stage 2 kit with their 472 cam, Sawicki 2-1 full stainless exhaust, screaming eagle 64mm throttle body and matching intake, bigger injectors, screaming eagle ventilator air cleaner and power vision tuner. I have power everywhere. I'm @ 129tq @ 2700rpm and stay over 120tq till 5200rpm. I make 100hp @ 4200rpm and 128hp @ 5200rpm and carries 128hp over 6200rpm. Bike rides stock at any rpm and only is nasty when I want it to be. 1st thru 3rd get its pulling front wheel off the ground and great wheelies in 1st. Im actually reconsidering going big bore because i only wanted 140 to 150hp but hard to justify spending extra 6 or 7k for 10 to 20 more hp. Hope this helps someone out looking for real data
I dont understand why it would cost 6-7k to swap the jugs and pistons and go big bore kit thats around $1,700 in parts you already have the proper intake and throttle body, you dont need to touch the head the proper tune you right at 150hp with a s&s 128 big bore kit based on the numbers you are seeing with that cam now i picked up over 20hp just swapping jugs pistons and intake 114 to 129 it started as a 107
@@detroitharleyscene There is more to it than pistons and jugs, there is pushrods, pushrod tubes, lifters, cam, gaskets, shop hrs for building it and dyno tuning.
Totally right. Bang for bucks is stage 2 on the 114. I have about the same Numbers,5 k cost
Just did the S&S 129 kit with the S&S 550c and I got to say it was worth every penny!
Can we get more info? I'm looking at this kit.
@@steve-vk6np i did a lot of other things also I have se cnc ported heads ward intake manifold 64mm throttle body. I got 152hp and 155 tq out of it its an absolute beast!
nice build. did you upgrade or change your bottom end? do you have thoughts on whether the stock flywheel can handle the increased power? looking at this build in the future. thanks.
@@andrescott534so far i ran it hard at the track all summer no major issues only a broken push rod during normal street riding swapped it out no issues since got about 6k of hard riding on the s&s 129 kit now
Thanks for the info re cast iron sleeves over the new ones
From what I understand, if you do the new S&S 132" kit, but add a 4-5/8"stroker flywheel, it can be a 136" motor, amazing for no case boring
Hell Yes!
💯
Original head fits? How about the screaming eagle cnc portet head? No manifold changes needed?
if i put on a big bore 128 do i need a bigger throttle body or just bigger injectors
Fuel moti offers a 132ci bolt on kití🤔
Do APE kits
107 M8 info please ..... if I bored Standard genuine HD 117 cylinders to 119 spec and used pistons from the M8 SE 107 to 119 kit would that work on the 107 shorter stroke bottom end ? is it the cylinders that are different lengths ( Hight ) or is it the pistons .
Not how it works. 107 has a shorter stroke than a 114.
@@freebehindbars8654 yes the stroke is different but as the cylinder is the same length for all M8 the piston deck hight is what makes up the difference between the short stoked 107 ... ie taller piston then 114 or 117 etc....

@@corevi6140 no, the 114 has slightly larger diameter pistons and a different crank.
@@corevi6140 I have a 124”, from a 107. Now it’s 4.25” pistons with a 4.375” stroke. Stock 107 has stock 3.937 pistons and the same stroke, since the same crank is used.
