They way you explain things is so detailed, yet so easily understandable. You’re a master of your craft, and the time you take to share your knowledge is beyond appreciated. thanks for the video
Wow, thank you! Appreciate the kind words sir. Hope you are well.
It is incredible the amount of time and knowledge you share with us
Your process is second to none! It’s the small details that makes all the difference. I watch a lot of builders on CZcams, but I’ve yet to find another person that compares to your precision. It’s 100% the reason Skunk Works will be my engine of choice for my 2016 Streetbob. Gotta get my Shovelhead finished and sold to fund one of these epic builds. But it’s coming soon!
this is why custom built motors are worth the extra cash! That bolt deal is the shit!
I really appreciate the details you put out here. You also prove up the difference between a quality machine/ engine shop and the wannabe back benchers ready to cut corners as soon as nobody is watching.
True craftsmanship and pride in your work. Unfortunately, y’all are a dying breed in a throw away society.
thank you very much for the kind words sir. all the best to you.
Yes the photo with the sledge hammer now I might be able to do that install ! Lol
Very impressive, Kevin! I'm so glad to have had you build the engine and drive-train for my Trike, the last Harley this old-man will ever own! Greg in Boise
Thank you Greg! I'm almost done building your actually. Will finish bolting on heads tomorrow, assemble rocker boxes, and get it in line to slide in the bike.
Amazing work... there's many shops that offer performance and machine packages but there's only a few who go about this like you do.. this is why your builds stay together..I've got friends who had a really good mechanic build their 96s into 107s and they didn't last longer than 40k miles before breaking the crank or busting rings etc
Really love these videos from across the pond 🇬🇧
I am glade your doing videos again I really like to Watch and listen do you it is so damn interesting and thanks again I wish there was somebody on the West Coast With your expertise
Thank you sir.
Love from DeKalb Mississippi USA 🇺🇸
It's a Shame your not here in Australia , I'd come and see ya
I totally appreciate your instructional style very clear & concise 👍
Your attention to detail is impeccable,thanks for sharing
awesome ,the mad doctor is at it again,great video Kevin
Always enjoy your videos
Glad you like them!
Thanks for sharing Kevin, we are going to be case boring, my TC cases soon for the 107" build you have the heads for.
Kevin, thanks for going the extra mile to give us an awesome build.
Kevin... I'm sooo impressed with the quality of work that you do!!!!! I just wished I had 1/10th of the skills and knowledge that you have on motors and HD... be safe and stay warm!!!!
Thank you sir! You as well!
Looking forward to it!
can wait for it. Kevin the beast
Love your work Kevin cheers from Oz
Thank you! Cheers!
As usual, one awesome video. Keep em coming.
Kevin, another great video, I just wish they were longer, or just more of them.
More to come! Thank you sir. Many videos in the works now. If we set up a camera and just dumped footage, it would be easier. to set up proper lighting, audio, multiple cameras, then editing is what takes so long. On average for our "cleaner" looking videos, it takes up to 1.5 hours to produce 1 minute of video. I would like to release at least 2 a week...just a matter of balancing time working for our customers, family, etc.
good to see you my friend
You Too Sir!!! It needs to warm up and stay clear of wet stuff so I can break in and get tuning!
Always scares me when I see a hammer in the title"make it fit"!🤣,great video
8:57 ouch, as a machinist that sounds awful. the lathe guys called that an 'interrupted cut' and they sometimes fill in gaps/holes/etc with an off white colored plaster-like material just to avoid this sort of thing. great channel, i like my sportbikes but might get a harley someday.
Great explanation. Even though you are absolutely worn out. Get some rest 😂😂😂
Im hearing that more and more sir. LOL. Our work load is very high and were doing our best to get customer's projects done.
Kevin....once again...I look through you're videos and always find something fun to learn...what do you think of 4-1/2 bore and a 4-1/8 stroke on S&S evo 124 cases???...asking for a friend 😁😁😁
Love the thumbnail of the hammer. Made me laugh
We need more people like you great video’s!! Question what’s oil pressure on 2015 street glide with engine warm 25 to 33 psi? Thank you
Have you ever seen a twin cam case fail in any sort of way, right there in the center where the new case bolt goes through? The reason I’m asking is because I’m considering having my spare 96” twin cam case bored out for larger cylinders. I’d like to go as big as possible without causing any problems with the case from boring it out too big.
Looks like you intend to use a Mexican speed wrench to make them fit. Good choice.
There will be some finesse involved lol
@@KevinBaxter And nothing says finesse better than a couple of pounds of steel on the end of a stick.
GOAT👍🇦🇺

I wish you had slowed down, and explained in the video when you were adjusting the head on the mill?
Kevin … Great video , as always to see the good doctor doing incredible work. Did you drop the big hammer on that finger?
LOL....no hammer thankfully but it was a pretty deep cut. one of those "almost could have lost it" moments.
I'm not sure if you actually read these comments but I enjoy your videos. I do have a question. Do you work on Victory engines?
Thank you sir. We do work on Victory engines.
Are these the cylinders that come with your power packages? I was planning on sending my bottom end to darkhorse, to do the crank and machine the cases for a 4 1/8”. But now I’ve been leaning towards just going with the 4 5/8” stroke crank and case service you provide, being that I will be ordering pistons and cylinders from you for the top end. Your word is gospel and I’d be honored to have a motor blueprinted by you. I ride with a few people who money isn’t really a issue for, that’s not the case for me unfortunately, but I always tell them that They are the money guys, And that’s great I wish I was a money guy but I happen to be the motorcycle guy and I’ll be damned after all the hours of work and research that I do that I get beat on a motorcycle by a money guy with a crate 120r or 143x!
Thanks for the kind words and support sir! The process would be the same regardless of stroke however, depending on piston choice (like ours), on a 4 5/8 the case would require an extra counterbore to clear the piston skirts as they extend below the cyl base a little bit. We spec every crank for our builds and Darkhorse does them for us...they can also do case boring as well and set up your bottom end. If you would like for us to do it, I can spec and order a Darkhorse crank for you, and do what you saw here...plus timken etc. If the project is time sensitive, they would be able to get it done quicker than I most likely...we are swamped.
Love the video. I know you use amsoil .but what would you use .for pime and tran or 20 w50 in all 3 holes on that new eng .amsoil vtiwn prime and tran or severe grear 75w140 and ATF
What are your thoughts on going with a S & S 100" Power Package 4" Bore bolt on cylinder and piston kit with no machining, balancing, or splitting the crankcases vs this on a 2002 Softail Fatboy which has timken crank bearing?
Looking to go from a 103 to your 117 this fall what would be the average cost to build so I know what I’m looking at and do I need to call now to book for winter
Hi Kevin, love your videos! Have you ever seen the case bore off center in relation to the crankshaft? Do you have any videos on Sportster Engines, 883 or 1200 ?
yes but only slightly and not enough to cause an issue.
Nice video, are those sleeved stock cylinders?
no sir. we have those made...brand new
How much does case boring typically cost? I wanna bump my 103 up to a 117 like this
Do it! I did and it’s was worth it.
👍🏾
Great content. Just had my 103 bored to fit the S&S 124. Noticed a bit of a leak possibly coming from where the cases split? Could that be the base gasket?
Thanks.
yes it could be, or the base itself.
Assuming you decked cases pre bore to equal deck level for bore. Otherwise when you adjusted Bridgeport "Y" axis cylinders could be non aligned with each other?
Hey Steve...i believe i understand your question...having to deck the case on one cyl but not the other? You are limited by how deep you can go to not get into the case dowels. of course i want to remove as little material as possible to maintain case integrity. i also want my final cylinder height to be equal and stock. This doesnt mean you have to deck both cylinders if only one requires it. That said, if a case was bad enough that it was of concern, Cometic will make custom base and head gaskets for us, so any imbalance of height could be accounted for with a thicker gasket on one cyl vs the other. in the end, if the cyl/piston clearance is the same, the comp ratio will be the same as well.
Thanks Kevin.
You didn't leave part of you're finger in the case did you ?
Them short skirted pistons really suck installing - especially those with real thin oil rings.
What case holding fixture is that?
how many have you had to deck the cases for the base gasket . i had an 07 that had a 110 kit put in and it ate base gaskets like popcorn on the rear cyl . harley kept telling me it was my fault driving it too hard ended up selling it .
i would say 25% of the time are they bad enough to require some decking or touch up. None of them are perfect however, a base gasket with a very small amount of aviation flange sealer works great. heat, crankcase pressure, overtorquing heads, etc...many causes and hard to say without looking at it.
Question; what is the function of the voids that you see under the deck just outside of the cylinder skirts?
I cant determine a function of any kind. I wish the voids werent there...would provide more strength.
What should the piston to cylinder clearance be?
that is determined by the piston type, manuf and bore size. most forged pistons used in HD require .0025 but check with the manuf first. Standard cast are less and hypereutectic can be even less.
That looks like a bigger hammer.
Mechanic etiquette... If it doesn't fit get a bigger hammer.
This made me smile! Thanks for sharing! Get the stats you deserve = P-R-O-M-O-S-M!!
