If the rings wear into the crosshatch pattern to seal, then they spin, doesn't that start the process all over again?

What's the remedy if you're crankshaft running out

Ive owned and riden harleys since 1956, (i am a geezer now at 85 yoa) they are infinitely better than they were. I mean there is no comparison. I have a local shop in melbourne fl work on it wen want something done. I spent a lot of money on a chronic problem with my battery. It would go dead overnight . I told the dealer the dealer i felt that it was grounded out ,nothing major just a short somewhere. They charged it , said it was ok. I rode it home and it was dead in the morning. This wen on and on they replaced the battery twice.(I paid. For all of this) no matter what the battery died overnight. I moved to florida , had he bike trucked as, the battery was dead.(couldn,t trust it hold a charge overnight) took it to the local guy. Told him wuat i thought the prolem was but the dealer couldnt find it. It took him less than 5 minutes to locate the problem ( it was grounding out just like i had said but the dealer had just replaced the batteries. That is why i have the local guy, southern v twin, here in melborme fl, as my go to guy. You may find out thats is a better way to go than yue mega franchise dealerships that jus want you money

When you build an engine for a customer is the break in process part of what you do before customer delivery ? Or do you give the break in instructions to them and hope they will do it properly ?

Well said sir!!!! Bravo!!! Applies in automotive also... I'm a dealership Diesel technician.... Word of the day TIME

2 valves and springs are lighter and require less work than one slightly larger? I wouldn't go back to an evo from a twin cam but I get more bang per £ than an M8. 75 ft lbs at 2 ½k with s&s 509 on a dyna seems useable. I would have made 1st taller and 3rd an 4th closer on the 5 speed but I'm in the UK where we have hills and small roads. 99 FXDL.

Does he ever actually answer the question?

Love it. I own an EVO, TWIN CAM & a 107 M8. All have their strengths but if I’m picking just one I’m going with the twi sound. Ahhhhhh

Just came across video series. Having major oil consumption issues on an 18 FLSB that I’ve had since new. For the longest time, would use 1/2qt in about 1000 miles. Now that’s down to about 450 miles and I only fill cold to bottom of stick and hot don’t like to see more than about 1/2way up. It’s going into air cleaner and cylinders, seeing ashy deposits in outside spark plugs. Today I pulled the CKP sensor out after about a 30 minute ride back from hardware store. Only got a few drops out of there, so not thinking sumping is my issue. This started when I was on a trip and I took to another dealer to check. They thought breathers in heads are the issue. Is this a possibility? Bike has just under 50k miles on it. I have appt with local shop now that I’m home next weekend and will have them do compression and leak down tests. Hoping that that’s not the issue because I really don’t have time for a big bore kit install at this time. I leave for Sturgis in only a few weeks. Anything else I should be considering at this point?

I am sorry you had to make a video explaining this to people. All I can say is not everyone is like that, and I appreciate you and what you are doing on this channel. Respect

Do you still offer the lifter tappet fit kit? Searched ariund on your website but did not locate them.

Dropped a lifter. He should have replaced them with S&S LIFTERS.

Ģreat video, thanks for that, could you post info on the bearing race puller tool to save me some guess work in advance, hopefully my race hasnt drifred inboard which Ive heard can happen, thanks again

You need a chain conversion if you have a belt. If you have a chain - you need a belt conversion.

Does it come with a bar to widen the lift so it doesn’t fall over//top heavy side to side?

Mine is getting a stop installed on each end of the tracks asap! Thank you very much for this information sir.

I never liked stainless steel fasteners. They will gall easily and inherently have less tensile strength than a good high carbon steel fastener. But customers would insist on them anyway.

Word Brother!!

It is there for a reason

Chains simply suck. Unless you have to have one run.

KB your the man on Outstanding info..! Stay Bless.

Whoever did the cam install etc.. didn’t have a clue.

It’s…… shouldn’t look like that, interesting.

Well, that's like all these people that phone me up and email me, and they say would you mind doing short survey for us? and I'm like sure do you have an invoice number for me so I can send you a bill? AND, that's when they tehy usually laugh or choke or cough and tell you that they want you to do it for free. Then I usually reply that my time is valuable, and I usually like to spend it with my family, not supporting some corporation's bottom line supplying data for their sales algorythm and A.I..... But I'm always available for consultation at $140.00/hr if they're still interested. Usually they're not.... and I no longer get phone calls or emails from them anymore. which is great! LOL!😊

You move REALLY FAST when you’re not talking and only making that squeaky sound. 🤔

Great video, gives me even more to consider. Especially when I thought the cam was supposed to be considered a "first mod," when upgrading your motor. You just made my head explode again. Lol

I have only recently found your channel and quickly subscribed. You certainly know your stuff and do a simple but precise breakdown of what you're doing, what to look for, and have given me the confidence to know that I CAN do my own work on my bike (to a certain extent) if I just take a deep breath and follow your lead. Thanks again.

Kevin, not sure if you can give me a route to explore. Stock 107 2018 M8 Softail, just under 50k miles. No issues until about 2 weeks ago when I was on a trip. Now using about 1/2qt of oil every 400 miles, about double what it was going through. Getting good amount of oil in air cleaner in addition to showing signs of ash on the spark plugs. Shop I stopped at thinks the breathers in the heads are bad. Power feels good, fuel mileage pretty normal, other than fighting headwinds

There's so many reasons I love your channel. The next time I'm in the States I'll happily spend hours looking for you missing box of bits just so I can look around your shop with your approval. The needle wiggle triggered me a bit. A radiused indent in your mushroom of just greater radius than the shaft being measured would reduce it, assuming it would stay aligned and wouldn't spin... Love your work.

What a quality product 25 k miles and failed what a joke

Harley’s are truly garbage overpriced slow and have been come a joke ,30k miles and that’s what you get for your money

Scopes on a Harley. I have a 4 channel Micsig I use for equipment diagnostics. I definitely want to scop my bike to get known good captures of the signals on my 23 ST SG. Nobody is doing this that so know of but it’s common practice in the automotive world. I’m interested in synching up the crank notch to MAP readings while idling for tuning purposes.

I cured my Harley heat problem........I bought a Honda Valkyrie.

My 2013 110 screaming eagle did similar as this one . They found roller lifters in the same as those , crank bearings bad , wrist pins were tight . All at 34000 miles .

What is your recommendation for an 06 Road glide with S&S 124

So what is the down fall on the early one? Dark Hoarse doesn’t offer a early style one? Thanks

Evolution... Absolutely NO Question.

I solved the problem of winter storage. I sold my car and ride year round. But I’m in south central USA, so the winters don’t last very long.

Every time I watch you’re videos it just confirms that Harley’s are a dumpster fire

Kevin I know you’re a busy man, but I value your opinion greatly. Thus said do you believe there is any advantage to having a external breather system on a twin cam ?

Several BMWs are documented to have gone over a million miles with zero issues.

Very interesting video, I have a 2018 M8 and learned alot about this engine from watching. Only thing I would suggest is that you talk through steps in the process for instance do's and don'ts when tearing down and specifics, ie tools, measurements, bolt patterns, torques etc during the rebuild. Would love to see the rebuild.

50k not that bad on a performance build, of course we want more. I'm sure I would be looking for more by then😂

As a retired mechanic, hat had a small bike repair shop, I here you Kevin !!

The lifters always tell you they're gonna give up right? Always a tapping right?

Bro. I told a family member the same thing and they didn't get it. We live in a world of 10 Gazillion genders. I worked 20 hour days 5 days a week and my wife at the time didn't understand it. My advice. Voicemail 😂😂😂😂😂😂 You job is repair, build. Not babysitting and coddling. Good post.

With all respect I feel I must point out one fact and it doesn't have anything to do with what you do but rather it is the fact that you used a thumbnail from a movie that I am certain I am not alone saying this so I will put it like this it is my opinion that you should watch the movie "The Goonies" because even though I understand it was an actor that played the part but that carecture was not only a good man but he was a hero and a friend. I insist that you take no disrespect from my opinion because it is just that my opinion and I also appreciate your videos and thank you for posting them sincerely.

There is a difference between a technician and a mechanic.

Dunlop/Phil great job thank you.
