Definitely happy with the outcome. It's like an (even) better version of the M2 I used to have. Once the kinks are ironed out, this'll be a wonderful machine. And I absolutely love the way it looks.

Was wondering about that 4,5k rev ceiling hammer specifies. Seems kinda high actually. Don't need (that) much more out of these motors.

I think its below 3k rpms for the first 50 miles then no more than 4k for the next 500. If you have an aftermarket ignition module, you can set the limiter. I think i set mine at 6k just because i dont like revvin it out and rarely take it above 5500. That and it gives you the choice of curves.
Is this what you meant about hammer and rpms?

Harley-Davidson recommends;
BREAK-IN: THE FIRST 500 MILES (800 KM)The sound design, quality materials, and workmanship that is built into your new Harley-Davidson will give you optimum performance right from the start.
* We ask that for the first 500 miles (800 km) and to wear-in critical parts, please observe the simple riding rules below. This will assure future performance and durability.

1. During the first 50 miles (80 km), keep the engine speed below 2500 RPM in any gear. However, do not lug the engine.
2. Up to 500 miles (800 km), vary the engine speed and avoid any steady speed for long distances. Engine speed up to 3000 RPM is permissible in any gear.
3. Avoid fast starts at wide open throttle. Drive slowly until engine warms up.
4. Avoid running the engine at extremely low RPM in higher gears.
* Do NOT exceed 50 mph (80 km/h) for the first 50 miles(80 km).
* Do NOT exceed 55 mph (89 km/h) for the first 50-500miles (80-800 km).
* Do not "lugg" the engine! Never ever below 1500 RPM. -- operating at very low rpm in high gears -- or subjecting a cold engine to fast starts with a wide open throttle during the break-in period.

S&S and others recommend;
1- Initial start up. Run engine approximately one minute at 1250-1750 rpm. DO NOT crack throttle or subject to any loads during this period as head gaskets are susceptible to failure at this time. During this time, check to see that oil pressure is normal, that oil is returning the oil tank, and that no leaks exist.

2. Shut off engine and thoroughly check for any leaks or other problems. Let engine cool to the touch.

3.. After engine has cooled, start up again and allow the motor to build some heat. Engine should be run no longer than three to four minutes. When the cylinders become warm/ hot to the touch (approximately 150į) shut the motor down and let it cool to room temp. Follow the same cautions as for the initial start-up, and continue to watch for problems.

4. Repeat this procedure 3 or 4 times. Each successive time it should take slightly longer to warm up and you can increase the temp slightly each time (+10į). You can be more liberal each time with the rpm, gently vary rpm continuously from idle up to 2500 rpm in the final cycle. Donít be too concerned with final carb settings at this time because idle speed and mixture cannot be correctly set until the motor reaches full operating temperature. The motor should not reach that temperature during these cycles. Do not allow engine temperature to become excessive. After the motor has cooled to room temperature for the final time you are ready to start the 1000 mile engine break-in process.

5. The first 50 miles are most critical for new rings and piston break-in. Engine damage is most likely to occur during this period. Keep heat down by not exceeding 2500 rpm. Avoid lugging the motor, riding in hot weather or in traffic. Vary the engine speed. Do not lug the engine. We recommend changing the oil at 50 miles.

6. The next 500 miles should be spent running engine no faster than 3500 rpm or 60 mph. Avoid continuous steady speeds, and do not lug the engine. Vary engine rpm. We recommend changing the oil again at 500 miles.
CAUTION: Lugging or running engine prematurely at sustained high rpm may result in damage to pistons and other engine components. S&S voids itís guarantee if engine is not broken in properly.

7. For the balance of the first 1000 miles the motor can be run in a normal but conservative manner. You can be more liberal with the rpm range and motorcycle can be operated at normal highway speeds. Avoid overheating or putting any hard strain on the engine: no drag racing, dyno runs, excessive speed, trailer towing or sidecar operation.

8. After 1000 miles, verify carburetor jetting and adjustment. Change the engine oil. Motorcycle can now be operated normally.

Someone posted this here a while back. I found it interesting.

https://youtu.be/xpoglovyy_8

In aircraft engines, we run them rich, maximum continuous power, low load, for the first 25 hours on mineral/dino oil or the rings donít seat. An old timer told me to ride it like you want to break it on break in... or it will break.

Might be something to that, given what they say in that video. Still... better be on the safe side.

@89rs1200

thanks! yeah those S&S recs sound kinda like what Hammer is saying. Worked out well for my X1, so I'm sticking with that.


Is this what you meant about hammer and rpms?

Yep, thanks.

That's interesting btw, the after market ignition module. Might look into that.}

Morning Williamscottrobertson,
That video from Motorcyclist Magazine really does dis-service for us that want their motor to last. They used a small metric motor and tore it down at 2000 miles. that was the end of it.
Also, personally I have a problem with the idea that something abused hard at the beginning will last longer. How does that make any sense?!
I believe most of the folks advocating hard break-in do not keep their motors for more than three or four years. That is what I see from most of the Harley Davidson owners I know.

Check out what these Harley Davidson mechanics have to say; https://www.youtube.com/watch?v=v_ONwjiosFI

I tend to agree with 89rs. If it were a two stroke dirtbike, absolutely ride it like you stole it. But those are supposed to be rebuilt like every 15 hrs. Unlike four strokes. Ive done both and with the four stroke, i tend to break in the engine gradually. This is my first big motor rebuild so i certainly followed the kits manufacturer/seller on break in. Just to be safe.
Hammer sold you the kit, follow their instructions. My .02

Yeah I always follow the manufacturers instruction. I was just demonstrating that there has been some research on the topic. Teledyne-Continental aircraft engines, the manufacturers break in recommendation - rich, high rpms, low load for 25 hours. Most depends on the engine manufacturers components. What is the cylinder wall material - steel, chrome, nikasil, ect ? The rings and pistons? Cast or forged? Is there Teflon on the rings? Many variables. What works for one engine may destroy another.
