Great Video, I own the exact same ring compressor. It works much better on a Harley if you flip it over so the Bottom stamped marking is "UP" its marked bottom for a car piston not a harley (on a car the piston skirt goes in cylinder first on A Harley the piston dome goes in cylinder first)
It’s common for big bore kits to use forged pistons. Why is forged preferred over hypereutectic? Hypereutectic have less thermal expansion and contraction properties and are just as capable of supporting these levels of performance

I just got a 129 big bore kit with 550 gear cam for my ‘19 SG. This video will help me big time with my install. Thanks for this great video.

I've done it the other way as well. Push piston and ring up thru bottom of cylinder then lower it too the rod and put wrist pin n c_ clip on.
Wicked vids love it, don’t forget to re torque them studs though they’ll wind out when their undone 👍🏼
That light solvent is that brake clean
Is there a 2nd video finishing the kit? The top end im referring to
Yes, there is an entire M8 build series covering engine and drivetrain th-cam.com/play/PL9agCErm6CET9FkRR86et23y6hfCmQduO.html
is going to 12 to 1 compression a problem and what other changes are needed to run correctly
Should I go for the 131 crate engine by screamin eagle or s&s cycle 132 power kit? I use my bike for long distance touring

I have just finished the big bore kit, I cannot find torque specs for motor mount bolts. 2017 ultralimited.
Hey I put one in and have piston slap, ever heard of this?
Great job Patrick. But I didn’t see ya hone the bore to get that x hatch pattern for the rings.
There’s no need. The cylinders are finished from S&S.
May seem very butch but, speed limits are always being monitored by camera and radar.
stay in your own little bubble
sometimes its a bitch by yourself sliding the cylinders on.good video
Especially if they are Keith Black or Wiseco pistons.
I have a real bike XL1200T and I'm not feeling jealous at all. 😂
I liked ur other music better!
129 big bore...😊
Call me silly but.. 1868cc isn’t enough you should probably just buy a faster, more powerful bike.
can put pistons in the cylinder first then install and put in gudgeon pin? be easier?
How would you slide the pin in?
@@redneckgearheadgarage495 leave the pistons out enough to have the pins access
out?
once he gets the piston ring s in the cylinder there is still space to put the pin in and out ?
