At approximately the 13:30 time mark. On the breather set up torque specs. It's 90 to 120 inch/lbs. Other than that great video.

I like your style brother. Your instructions are easy to follow and on point. My only observation is the torque values for the breather bolts where you stated ft. lbs., when the shop manual states it should be inch lbs. Tell me if I'm wrong. My 2018 Ultra Limited 107 has 11k on the clock and so far I don't have any issues but I want to replace the compensator, cam chest lifters and lifter cuffs to make it bullet proof. I sure don't want to replace the engine due to lifter twist of compensator noise makers. What were these HD designers thinking? You've earned a new sub from me Patrick.

Hello Patrick, can you please make a video of the removal and installation of the rear wheel of your Fat Bob 114? My tire is worn and the change at Harley is very expensive. What do you have to pay attention to? Do you really have to adjust the belt bolts or does the rear axle also go out like that? Such questions arise for me. Thank you Thomas

Great video. One question I have is why you would install the quickie push-rods vs solid ones.

most people will use the quickee's when doing a cam job. So I wanted to so the adjustment. Also, I will be swapping cams at some point and using the quickee's is easier - Patrick

Hey, what's the torque spec on the knock sensors? I can't find that anywhere

Hey Patrick- open invite at my place to do this to my Road King! I got all the carnitas and fresh tortillas you can eat as well as a case of beer! Come on down! Thanks for the video. You make it look easy!

What model and make is your torque wrench?

@eugenehill3167 11 ай бұрын

Thank you I appreciate your detailed information! My question ? Putting these heads on the milwaukee-eight will achieve and give you what benefits? More horsepower more torque ? I understand this is a step for when you replace the cam, but is there any benefit at this point in the built ? Thank You!!

remember early in the vid we saw him fitting upgraded valve springs? The high flow heads and springs go with a high lift cam which we assume he has done.

@johnbeardsley7360 9 ай бұрын

yes i understand its several steps but the final value number you gave is 19-20 the book says 25-27

@stevecuthbert8856 Жыл бұрын

Once you measure for the spring bind on one valve do you have to measure each one or one and done?

Why did you use screaming eagle heads instead of S & S heads?

Do you think the motor should be rotated with the plugs out until you have good oil pressure at the rockers???

yes

you say the final torque for the head bolts are 19-20 but the book says 25-27...can u explain please?

thats not what I said. It's a multi step sequence that starts at 9:20 in the video -Patrick

@thomaskirkpatrick4031 Жыл бұрын

With those breather bolts, I believe you meant to 90 to 120 inch pounds? Not foot pounds.

@BUILDEMTORIDE Жыл бұрын

ummm for the breather bolt you said 90 to 120 ft. lbs not in. lbs. might wanna add a notation to correct that (it should be obvious but....)
