[@jameshenderson7224]

I love it when 40k is considered high mileage.

[@Donfleebie1]

My 2012 103 ran super hot, and had detonation problems from the first day I had it. I recently got rid of the cats, and put a tune on it, and no more detonation, and much cooler

[@13699111]

Thank you for posting this series.

[@Sam590ss]

Man it's been a busy summer! Finally getting a chance to catch up on the vodoo that you do so amazingly well. About to pop the top on a cold one and watch a few more. Thank you Kevin for what you do here!

[@jamespotts2188]

Enjoy learning new things and I definitely want to know what happened with this engine!

[@tcb8295]

Another great video as always Kevin. Have a great weekend and week next week!

[@mikelovestoride2367]

Enjoy your videos, I was suprised to learn Harley uses Forged pistons, I expected cast. I have a 2004 with close to 70k miles so I may be coming for a visit soon. Thanks again!

[@kevinmccarty6343]

Awesome. This is hitting close to home. My 05 softail was lean, now very rich and I have those struggling issues certain times...😬

[@KevinBaxter]

there has to be a balance for sure.

[@TheBustedNut]

Thanks kevin! Love the twin cam series.👍 keep em coming please sir.

[@gerardsalmon4960]

Really enjoy all your videos, but why do you consider 40 thousand high miles for that engine, i have a bone stock 2013 FLHR-P with a 103 & hopefully plan on getting way more than that on my engine with good maintenance

[@LukeA1223]

Why don't I put a drain plug at the bottom of my crank case where you found all that sludge? Seems to me I'd want to have access to that lowest spot. I'm upgrading to an S&S crank case, though, the Harley cases were fairly clean when I took them apart after 41,000 miles, is sludge buildup/ sumping going to be a problem there too? These videos are a confidence builder for when I finally get to put my 2013 103 back together (I don't have to rely totally on the service manual , though, God knows I paid enough for it). Thanks Kevin, I appreciate all the expert info!

[@KJMonk]

Sorry push send by mistake Thanks for looking & any help i be grateful for cheers kev

[@jimtiffany3713]

Always interested in the final results of the builds...curious about this one

[@Greenjeans2020]

I have done more than one cam job, hydraulic or gear drive update and never seen as much sumping or nasty oil. Of course not nearly as many as you. However, it sure is getting to be a concern. Great video!

[@KevinBaxter]

Thanks for sharing. This series has had more than i expected...just grabbing 8 engines at random.

[@coryknipe5471]

Just keeping up on all your videos as presently tearing down my 103 in a 2009 trike - 45k -km. did you ever come to a conclusion of the sumping? Thanks from Canada and keep up the great videos.

[@ncautolink]

Thank you so much for your videos. I’m moving to North Carolina from Texas this summer and I’m planning on visiting you soon for you to build me a motor. I already installed S&S cam plate w oil pump and tw222 cams using your videos. But my runout is 7000 on a new motor I bought a year go for my 07 Street Glide and it only has 5000 miles so I’m planning on getting dark horse crank and go bigger displacement from 103 to probably 110.

[@KevinBaxter]

Look forward to it Tim. Thank you sir.

[@jamesfatula1365]

Thanks!

[@KevinBaxter]

No problem!

[@fogit4668]

A Jagg oil cooler with the fan might solve a lot of heat problems on this one. On top of that I am a big supporter of thermal coatings on pistons, combustion chambers, valve faces, exhaust valve stem and port.

[@richardalvis4695]

the carbon is like you firing up your grill. the charcoal stays hot.

[@mitchelldarnell5334]

Good job. Does it have the cylinder cut off when it gets hot? My 08 got hot in ND sitting in all those HD'S running around up there. Mine shut down the one cylinder, told my Son, exit out of this mess as soon as you can. Sturges once, probably won't ever get stuck in traffic like that again, too hard on the motor.🥴

[@KevinBaxter]

Not in this year...however, there is a "hidden" table in the tuning file that would richen fuel mixture as the engine got hotter to help cool it down. Most could not access that table or even knew it existed back then so i doubt it was utilized as it could have been.

[@mitchelldarnell5334]

@@KevinBaxter Learned something new again! You have a wealth of knowledge SIR!!👍

[@robs3670]

Just discovered your vids. At 69 till too young to spend all day on KZbin. But your vids can be truly addictive. I have a 2001 TC so finding those teardowns the most interesting so far. But must admit, that any engine deep dive with someone who knows what there doing is like candy to me. My only question is how to you keep your hands so clean? Are you using a hand model stand-in?? ;-)

[@jeffhawkins711]

Good job on the videos .

[@ephraimgarrett4727]

What about the piston oilers? Leaking?

[@jimwilkins8753]

Probably a silly question but can choice of engine oil and its performance, or lack thereof, result in excessive engine heat?

[@KevinBaxter]

Absolutely....

[@richardalvis4695]

the close up of the plug and the oil drained would have been cool. its like right before coking oil?

[@bullast2046]

So the heat didn’t hurt it bad? Cause I’m in TX now and mine runs DAMN hot in traffic (300 is not uncommon).. need to add a cooler

[@sidneysnottley6414]

..and another pearler of a video - Cheers.

Hey mate , just wondering what’s happened to the build videos ? Do I need to become a member to view new videos ? Thanks 🇦🇺

[@ianbouchardmusic7203]

Love learning from you! Where is part 2 for this video?!

[@raymondjohnson6496]

How long does cam and lifters last on a Harley and the oil pump I hope every 40,000 miles you got to do this on a Harley

[@harleyhawk7959]

my O5 t.c.big bore ported.. bored and stroked, balanced S&S crank, timken inserts and bearings, S&S tappets, S&S pushrods, 545 reaper cams, S&S geared. new valve springs, valve guides, new 51mm throttle body, screaming eagle cam plate. S&S oil pump. keith black forged pistons, new injectors. is this a good Build?

[@KevinBaxter]

you have great equipment there. assembled and tuned proper...should have good results.

[@richardalvis4695]

make sure the head and block are mated is what you were saying?

[@richardgonzalez8327]

Do you support love jugs on the m8 motor I have a 2017 roadglide m8 going on two blown motors , love jugs the cooling fans ??

[@KevinBaxter]

there are a few companies out there that make fans. its a great addition if heat is a problem.

[@chrisbiggs3301]

Any preference on oil cooler for a 110 jaggs? Or ultra cool?

[@uncletoddsgarage]

Loving your videos!

[@danielsouthern411]

Great video

[@johnymc7139]

Hi Kevin, oil looked pretty ugly, what kind of oil was he using and how often was he changing it? Maybe overheating because oil not changed often?

[@danielgaskell5490]

Dirty oil won’t cause overheating; accelerated wear - Yes.

[@richardalvis4695]

dude you are the man

[@KevinBaxter]

thank you sir.

[@seekerofthenarrowgate8716]

Greetings Kevin. What is your opinion on running non oxygenated fuels compared to ethanol blends? Thanks for your time.

[@KevinBaxter]

I think its great if you can find it and afford it. No additives, no ethanol, typically higher octane, no phase separation to worry about, less moisture....all great points. I did a video YEARS ago called E85 as race gas. I gave a lot of details on ethanol and effects. Maybe give that a watch. Thanks.

[@jackklarich7045]

I am wondering why I have not seen any M8 Freewheeler trikes with sumping or oil transfer

[@guyconnell2250]

So he's got a non-OE camplate, it seems to have been running rich, and I bet you'll find aftermarket cams. So, like maybe most "worked on" Harleys, this bike was likely never tuned optimally.

[@KevinBaxter]

it may have been tuned well for an average bike...i dont see typical damage from a "bad" tune. It may not have been appropriate for a trike though...heavy load, etc. I will be putting the cyls in torque plates. i believe it just overheated, which wouldve deformed the cylinders and created more blowby. That's my theory.

[@Duey_diditGarage]

Glad to see another SE cam plate sumping

[@KevinBaxter]

i can not blame this on the oil pump or cam plate. both looked healthy. I will be putting the cyls in torque plates. i believe it just overheated several times, which wouldve deformed the cylinders and created more blowby. That's my theory.

[@Duey_diditGarage]

@@KevinBaxter yeah just goes to show there is so many variables of what can cause sumping

[@MegaCusco]

Every single orange cam plate I have ever seen, with any amount of miles is worn half way around just like this one. I think it is due to the design ,more specifically the wave washer between the pump gears. Combined with no seal between the pump and plate surface...junk set up. I will never use those again. Spun an engine over with the plugs out and cam cover off. Oil bleed off gushing down from pump /plate mounting surface. Just begging for scored piston skirts. Never again orange screamin beagle cam plates.

[@chucksnowdon4573]

Ahh huh man. I've been wanting!!! For your next episodes

[@rafaelsantamaria5863]

Can lugging the engine cause the excessive heat problem? I’ve noticed a few trike riders seem to lug along during trips and charity rides.

[@georgespain6121]

Kevin, why couldn’t a gps altimeter and thermometer be integrated into the performance module to account for air intake temperature (keeping air/fuel ratios at optimum) and altitude changes? It seems like this would improve drivability and gas mileage while maintaining peak performance, or do they currently account for this info.

[@gregoryranlett7868]

Thanks, Kevin!

[@KevinBaxter]

youre welcome. thank you sir.

[@timdavis8154]

Will the crank need replaced or just a Timken bearing upgrade?

[@thomaskirkpatrick4031]

Speaking of running hot Kevin, how's that Georgia heat and humidity?

[@joeabbott7839]

How the oil pump return oil back to tank or is the oil return dirty

Kevin, what tool is that you use to split the cases ?

[@sean8470]

kevin you are doing a great job with these videos and your work i'm sure is 2nd to none. One thing just an observation is i'm sure Harley corporate are not fans of these videos ;)

[@hddynaroy1111]

Kevin, I really appreciate all of the videos. I have a question related to an M8 that I am working on. Where can I buy a metal cam/crank locking tool. The Felton units I find on the internet just don’t seem to work well or last? Any suggestions?

[@tommontague5721]

Keven, Do you think a Power Commander might help the heat problem? Or because it's installed in a trike and running hot is the nature of the beast?

[@staynless7]

Can the front and rear cylinder timing be different? Could the rear cylinder have been over heating because of a difference in spark timing?

[@KevinBaxter]

yes sir...it absolutely can. on heavy bike, especially trikes, its best to tune not only by AFR, but by temp. as you know, timing plays a big role in that.

[@michaelsmartin5388]

new to the site, what is meant by sumping? thank you

[@ryandavidson523]

American flag reflecting in the cylinder at 7:02-7:09 is a pretty cool unintended special effect

[@GHOSTINPLAINSIGHT]

All I could really see is the American flag and I'm most certainly good with that! Murica! I trust Kevin's diag of the issue. Just good to see the flag without some MSNBC reporter feeling that it was to much for her delicate sensibilities......snowflake......

[@nickglorioso6266]

Great job 👍👍👍

[@richardalvis4695]

is that a high mileage low maintenance engine your working on or is it the weight of the trike overworking the engine when you drive it sporty like?

[@hdrider05]

My 103 with woods 777 cams,power vision with no dyno tune,gets very hot very fast. What can I do to cool it down ?

[@razzrasmussen5773]

Have you heard of DK customs? What do you think of their keep it cool products for engines? Thanks for your videos. Hooah

[@juanc3121]

Hi Kevin. Do you know what is the normal operating temperature range of current sportsters with the temperature sensor in the rear cylinder? I couldn't find it in the owner's or service manual. Thank you. Regards.

[@KevinBaxter]

I pay closest attention to cylinder head temp at the base of the spark plug. 300-320 degrees after a moderate ride with no traffic is great. If that starts creeping up to 350 and higher, valve seats can begin to fall out. This temp reading will be different than what you see with your engine temp sensor. That will always be much lower.

[@richardalvis4695]

could you have said low maintenance/ hot rodding engine?

[@richardalvis4695]

you sale camplates right?

[@Jim_Berry]

Very interesting.

[@carlitosantiago8951]

[@brandoncouch5925]

How do I become a member?

[@fieldmanstyle1831]

Was it a mistake not to upgrade the oil pump while upgrading the cam plate? Would that alone have helped it run cooler, or would an oil cooler still be recommended on these engines. I have 2 TC88'S and am planning the plate/tensioner upgrade and am debating upgrading the oil pumps. Thanks for putting out info on these older engines!

[@KevinBaxter]

that was an upgraded pump that came with the cam plate. On a trike, certainly would have a Jagg oil cooler and a Jims Forceflow Fan for sure!

[@sashunter4352]

[@davidfellows6250]

i had a buddy who thought in the winter he could run his bike in the garage to keep it charged. maybe this guy like to idle his bike for a half hour at a time.

Fairly new to your channel.I do have a question.I have a 2005 Deuce.Had 8900 in 2019 IV only have 10400 miles now.I use recommend oil.Took. to a shop for a rear tire they without even asking changed the oil and put in 20w 60 IV only used 20 50 synthetic.Should I leave what they put in or drain it and use what I normally use?May be a dumb question but I don't want to ruin the motor.

[@KevinBaxter]

That's not very many miles. On a TC, ive never seen the need for anything thicker than 20w50 UNLESS...you live in an EXTREMELY hot area and i would only run it when its very hot.

[@Dixifrog]

Kevin would you still recommend 20w50 for summertime stop and go traffic in downtown Atlanta? The mechanic that rebuilt mine used HD 50W to break in and recommends using it most all of the time. 10.5/1 compression.

[@rickbush2914]

I personally wish I had seen this Service Bulletin before I bought another one: static.nhtsa.gov/odi/tsbs/2017/MC-10124214-9999.pdf The bike has no issues otherwise but I guess I can cancel future oil changes.... I have to put new oil in it weekly. It seems to me that if they can predict oil consumption at this level in the Milwaukee 8, they can also engineer a fix.

[@treefrogs2894]

Maybe oil pressure is too high pushing excessive oil through the port oil pressure regulator failure I'm a little bit worried I am running excessive oil pressure on my bike my bike is custom Softail chopper I have a bigger oil pump oil pump spring adjustment to increase the pressure aftermarket I do not keep my oil pressure below 10 psi I should say between 8 to 10 psi also I have a oil cooler with a thermostat electric fan also I have jug fan all the stuff I custom myself I am running a mikuni carburetor I still have to tweak and adjust it also I have a h i - 4 ignition system I am running a Andrew 23 cam I upgrade the push rod I upgrade the lifters the bike only have 8,000 MI

[@CapnDrift]

Vacuum leak with the electronics pumping more fuel to compensate? To be honest, I'm fuel injection ignorant.

[@Chase_N]

What temp is too "HOT"? On my powervision the temp sensor says it's running 226*F-246*F unless I stop or significantly slow down like on my gravel rd where leaving 2nd gear or going over 25 mph is asking for trouble. Is 250*F too HOT? 260*F? 280*F?

[@KevinBaxter]

I pay closest attention to cylinder head temp at the base of the spark plug. 300-320 degrees after a moderate ride with no traffic is great. If that starts creeping up to 350 and higher, valve seats can begin to fall out. This temp reading will be different than what you see with your engine temp sensor. That will always be much lower.

Kevin did you ever know Brian Hozical before he moved back to Australia. You sort of remind me of him with your ability to work on anything. Brian was always thinking out of the box when building a bike. I was just curious to see if you knew him. I know you know Beno Rodi because he. Is there in Winder also. I have been watching your videos and wondering has S&S had any problems with the 107 cu in engine. I have an 02 Ironhorse and have only had electrical problems so far. Thanks for all the good videos and the next time I’m in Atlanta I will come by.

I’m waiting for your live video. Sure wish you were closer, I live in Rainbow city Al. Do you have any experience with the Rocket3 Triumph. I heard you say you were working on a Norton. The guy Brian was a British nut and has videos on KZbin. I think Thunderheart tried to make a simple system hard, sorta like all appliances with the printed circuit board.
