Is it legal in California

I was JUST thinking the very same thing....someone is butthurt 😂

[@BlockheadMoto]

The bike was dropped off for the 131 kit *before* we put it up against the 110, so it was happening before that, lol. Build schedule got pushed back though, so I picked the bike up and thought it’d be good to do a comparison video on it w the 114 since I had so many requests for it 🤷🏻‍♂️

[@LL-pr8um]

Just bustin’ your chops! 😂. Love the channel, and enjoy that 131!

[@BlockheadMoto]

[@scoobymoto9858]

Man, he makes it look so easy. Definitely impressed. Can’t wait to see you tearing around on that beast.

[@mojomanmurph1925]

Got over 3,000 miles on this big bore in all types of riding conditions. It is freaking fast and a total blast if you can ride it above the 3,500 rpm range. Con: the engine and exhaust will get very hot and you want to be moving above 50 mph to keep it cooled down. Not the way to go if riding in city streets with many red lights or stop -n- go traffic.

[@jamesturk1749]

I’m thinking of stage 3 for that reason…still plenty of power

[@Spataman9]

Man its crazy how harley has essentially kept the blue print on the engines the same for so long, I had to do major engine work on my shovelhead and im telling you its basiclly the same process just newer parts inbetween

[@levib4233]

Block you’re a mad man putting that 131 on the lowrider I love it

[@BlockheadMoto]

Levi B Had to after trying it in the touring 😁

[@levib4233]

BLOCKHEAD I could hear the gears turning in you head during that video, so I knew it was only a matter of time before you did it to the low rider. You’re gonna have to get together with Shadetree and put the lowrider super agains road King Kong

My brother is the Chief Mechanic at Nassau HD in NY. I like watching these builds, even though I haven't a clue. lol

[@wombat8882]

I've been pondering this kit, vs S&S 128, vs a good Stage II build, for my 2018 Heritage 114. I have seen Stage II get up to 130 FP and 120 HP (browse dyno charts on Fuel Moto). I have seen the 128 get up to 147 FP and 124 HP (check Moonshine H-D for a Softail 128 video). And then, we have the 131's advertised 134 FP and 124 HP (something like that, may be a few off with those numbers). On paper, the most expensive option only matches the power of the cheapest option, and loses to the middle-priced option. But what I am wondering is what happens if you take a 131, put on Fat Cat pipes, use a good cam, and Power Vision tune. Best I can tell, nobody knows, because the people buying 131 kits generally want to maintain their factory warranty so far. Guessing in a year or two, we'll have a lot more data, and see the true power of 131, but for now, it's a tough choice. Very interested to see how your build goes. Thanks for posting!

[@evil_musclemuscled3814]

Quickie push rods will eliminate having to remove the heads at a later time . If you change your mind later a mechanic will cut off the pretty push rods just to make the job go by quicker

[@mattthegreeter9074]

Thought I was having a cam problem, but ended up being something else. Putting it back together I went with adjustable pushrods because, well, it saved a ton of money (I did upgrade the roller bearing though, like you did). My bike's an '09 FXDL and is my only bike so I can't afford to muck it up too much! Been a great bike since I got it. Have to test ride one on the Softail platform soon just to see.

[@ReccebyDeath]

You have to have Chris and some of the other techs in to get into the really technical questions in the near future. Keep up the great work!

[@metalplane3]

Avgas 100 LL creates Lead Salts. Very hard and abrasive. The reason aircraft engines are usually only rated for 2,000 hours of operation before overhaul is due to the excessive wear from leaded gas.

You two literally read my mind. Plus I just like the look of the standard.

You'd better get a steady supply of rear tires lined up. 😁

[@JoshsTruckingadventures]

You’d only be able to get the 124. The 131 is only for the 114.

[@BTDTChino]

That's the big bore kits. You can buy the 131 crate, and slap it in there.

[@bradybingham2317]

Congrats on the Stage 4 131 kit on your Lowrider S Blockhead! I’m not gonna lie, I’m just a little jealous! 😁

[@lazzyrj1]

It’s crazy to install that engine with all that power and not upgrading the front and rear suspension first . Need to be able to control all that power . You should look into Ohlins . They have kits for the front and rear .

Super Duke 1290r still offers the largest mass produced piston bore of 4.25 inches vs Harley 4.31 inch bore. Big Bang for torque.

[@jamessouthworth1699]

I thought the word tappet came from the days before the hydraulic lifter, back when they were solid lifters and made more noise.

[@ecrusch]

That's correct.
