- Twin Cam Harley Davidson’s are the brands leading workhorse, being such they incur plenty of wear, tear, are overworked and underfed. inspecting, checking and replacing these parts will guaranteed keep you going longer than the rest of the HOG pen
Cam Tensioners are going to be the Most Important, as this is the heart of the bike, this is a big part why the twin cam gets such a bad wrap but if you maintain doing your maintenance it should be no issue
1999-2006 Twin Cam Tensioners - Check and Replace shoes at least every 10,000, The little plastic particulates like to drop off in chunks causing plastic bits in the oil pump if not addressed which lead to a whole host of failures.
You can replace the shoes to get by, but it's only right to do the full tensioners every 25k-30k miles and if you’ve never touched it, the previous owner didn’t either, and if you’re already in there you might as well replace primary shoe, gasket, Primary and Cam cover hardware and Primary, derby cover gasket, check the primary tensioner and check chains for excessive slack.

make sure the cam plate isn't bowed which is common with the sandcast oem plates when your just replacing shoes,and even you're on a budget it’s probably wise to check your oil pump gear rotors for wear and have one on standby for replacement and most likely it will be worn from its entire life riding on the out of true crankshaft, better to replace a 150 oil pump than pay for a 250 tow to do the same thing all over again.

You must check crankshaft runout before making any cam or performance choices. Also keep in mind before you install any performance products as a installer this is your responsibility to calculate and check
Coil bind, Valve to valve clearance, and valve to piston clearance with the Grind, open, close, duration/s, valve lift, lift @ TDC
So that way you don't have a piston kiss your valve and then that's all she wrote.
www.feulingpar... Runout gauge
www.jpcycles.c...
Chain drives also give much more leeway of crankshaft runout, this is the biggest factor when choosing chain or gear drive setup your crankshaft must have less than .003 Thousandths runout on crankshaft axis, .012 thousandths is Harley’s serviceable limit for Crankshaft altogether, So before you think big cam you might be thinking big bottom end and built heads. Darkhorse crankworks are the best, if you're not going to replace your main crank bearing and have your crank trued, don't want excessive gear drive sound, chain drive is the way to go.
If you really care for your bike or your customer wants a bulletproof upgraded setup you can install or build your own Hydraulic Conversion kit. Which in short means You can Convert 1999-2006 Spring tensioners to hydraulic with Screaming Eagle conversion cam plate/oil pump and Andrews conversion cam combo or Fueling kits are popular because of their price point and inclusivity of all the parts required.

Please remember Whenever you replace cams, always swap inner cam bearings, even as a safety measure it would be wise, you absolutely don’t want one of these little rollers to seize up, to then seize your new entire cam chest

I "upgraded" from a Sportster to a Twin Cam.... now I realize the Sportster was the real upgrade.
Yeah I sell parts for living, if that says anything. Sometimes I swear they made the twin cam because the evo was too reliable sometimes.
When I sold my Sportster and got a Dyna TC 96, all hell broke loose regarding reliability. Replaced my Dyna with a Road King Screaming Eagle big bore. Most unreliable bike I have ever owned. That was a money pit. Finally went for a Triumph T120 Bonneville and starting to enjoy motorcycles again. Still miss that Sportster. It was as reliable as the Bonnie. Sometimes I think of getting an M8 but the HD is charging an arm and a leg for them. Can't really afford one. And with the new set of issues that the M8 are suffering from, i think will keep the Bonneville for some time.
@@atomicgrasshopper4391 sold my sporty for a Vic, I work for a parts store that sells almost 😅 exclusively Harley parts. With all the issues I see with the new M8’s and Dealer spats and fighting over warranty issues my only motorcycle will be a Indian even after they screwed victory. I’ve just been hearing nightmare stories from the dealer across the street. They need a aftermarket Clutch pushrod because they are spewing all your trans into the now leaking primary no shit, crankshaft runout issues on brand new bikes, blowing head gaskets left and right and your waiting 28-32 weeks for parts, not labor on stock bikes nothing modified. Stators and Regulators on back order, They are screwing their customer base and it’s going to bite them like you showed with a new bike obviously.
That's why it's called the Twinscam.
Upgraded to the screaming Eagle cam plate kit. Regular fluid changes. 2005 Harley Davidson lowrider - Tc88 - 40k miles and Still sounds like a band of Angels.
I'm 70 yrs old .I've rode Harley Davidson all my life . I must say I've been riding a twincam since 02. Of course I had to spend the money nessssary to make my 23k dollar bike Dependable. I always had much respect for HD but ever since I paid all the required fees to own my motorcycle , I had to turn right around and spend another 15hundred to get it right. That's me doing the work. The bikes aren't getting better , cheaper for them , to hell with the consumer !
That's why I don't buy new bikes. I know I'm going to be pulling and upgrading problem areas. You can find clean bikes with less than 20k miles for 5 to 6 thousand all day in my area. 20k is nothing for the basic components that don't get changed.
Hi 👋, I am 72+ years young, I have just purchased my 4th HD my 2s Deuce, from the uk , I am English retired living in France, I paid around 5K , it is in very bad condition, it has not been on the road for over a year, I am slowly going through it, stay safe ride free, France
Good stuff. I am a fanatic about maintenance on both my 103TC's , 3 hole oil changes etc. Always run AMSoil and clean that air filter! I made my own maintenance spreadsheet
That’s awesome, most people are surprised their bike has 3 different oils. Let alone thinking that far in advance kudos to you 👏
The TC103 seems to be the only ones not having issues if u leave them stock ish
Tensioner replacement at 25k, crank runout, oil sumpung. I solved mi TC88 issues when I bought a DCT Wing.
I have an 02 Electra Glide with Stage 1 & 2. I upgraded the cam chest with Fueling components including high capacity oil pump, and S&S 510 cams. No cam issues going forward and the Harley will never leave my possession, however I bought an 08 GL-1800 to crush the long distance miles.
Hi 👋, I am new to your work shop, I had a 1999, DEUCE, 88 . around 2006/7 I had screaming eagle, big bore kit put on, I’ve had my cams ignition and lots of other goodies, DD 2-1 exhaust, I had to sell it in 2019 because of my ex partner had scammed me for 10 of thousand of pounds, it was over 55,000 ml on the clock, unlike like my ex partner my bike, never let me Down, I used to live in the UK i now live in France.
All of my HOG rally’s where I travelled all over Europe, sometimes do around 4000 miles in two weeks. I am looking forward to the day hopefully I will get another bike, Ride safe guys, enjoy the summer it’s on its way,
PHIL FROM THE DARK SIDE OF THE MOULIN FRANCE.
How did you get a Deuce a model year before they came out? (2000-2007)
Hi 👋, sorry it was 2000 , I have just purchased a 2003 deuce, it is in a very bad condition, I have just replaced the main belt drive and sprocket, and Jim’s upgrade inner bearing on output shaft, new coil and leads , and rebuild the HSR42 carb twice all new jets,
And I have found that it has been cam S&S G510 , not sure if it was 88 or 95 I will find out over the winter months, France.
The audio on this post leaves a lot to be desired, the information was great.
Got rid of all the junk chains and tensioners on my 02" Heritage at 15K. Upgraded to S&S gear driven cams, the only way to go to make it bulletproof.
I have an carbureted 02 Electra Glide TC-88. I had my cam chest rebuilt three years ago at 35k miles. I used Fueling cam chest and high capacity oil pump components and upgraded my cams to S&S 510’s. I also had my carb rebuilt with Ivan’s Performance jets. Three years later my bike is still running strong and I have no reason to trade it or sell. I love the old girl!
How did you determine what jets made your bike run right?
I have same bike.
S&S 510 gear drive cams in a 2000 fxst with hooker 2 into 1 60000 and still do my own maintenance runs perfect
I like what you have here. I don't know if anyone has complained but your sound level drops about a minute into the video.
I've had many bikes, only my currant is a HD.
It will be my last.
They are yesterday’s technology at tomorrow’s prices that what pushes me away from them.
@@jon5423 I like it now, i'm just angry it took so much time, energy, and MONEY to get it right.
I am keeping my 99 EVO powered Softail Custom. It gets me where I want to go without problems.
when was the last time you checked your lifters....
@@hawkdsl 40,000 miles ago when I replaced the inner cam brg. with a Torrington. I am still running the stock cam which is not a problem with the later stock lifters. I only have 64,000 on it. I have friends who have well over 100.000 by just replacing the inner cam brg. But they are all running the stock cam. It is when you change the cam that puts a strain on the lifters. A mild cam is OK. But high performance cam really puts a strain on the lifters.
@@jimkraft9445 Good to hear, but my point was... they all have problems. Every new iteration of HD motor has a combination, and whatever engine we run, we tend to believe is the best one... Which of course is not true.
That is true. I put 60,000 miles on an 84 XLCH Sportster. At 30,000 the crank pin flaked off. Total rebuild. After that it was trouble free. When the ignition module went belly up, I changed it to points and condenser. No more problems with that.
I started on a 1942 "45" flat head when I was 14, back in 1955. I am not new to harley problems, but that old 45 took an awful lot of abuse from me and just kept running.
I am 82 now and do not do any long rides anymore. Just putt around the back roads where I live and to town which is only about 7,500 population. I will say the EVO has been the most reliable of all the bikes I have owned. About the only other thing I had to replace was the stator. Since I do all my own work in my own garage, I like the simplicity of the EVO. I can change carburetor jets in about 10 minutes without removing the carburetor.
@@jimkraft9445 Still riding at 82 is awesome. I'm sure you have hundreds of great stories to tell riding that long. Stay safe, and keep the shiny side up my friend!
I replaced my tensioners with gear drive on my '01 FXDX. SE cam chest and oil pump, S&S .510 cams, Supertrapp, Mikuni, K&N
Is the gear drive possible on fuel injected? I was told no but find that hard to believe.
Gear drive has nothing to do with fuel.
@@BobO-ho9zv It does keep your timing perfect compared to chain drive
@@dennislett7896 gear drive is preferable IF you're pinion run out is under .003"
99-06 also need OEM 33443 JIMS 33443-84 TC oil pump/evo tappet block alignment tools 🧰 (X 2)
Definitely not needed. Oil pump alignment can be done by rotating the rear wheel
Wow brother you are extremely thorough and I appreciate it exclamation mark
If you purchase a Flo reusable oil filter for around: $120 you can see everything the magnetic pre filter and stainless screen catches when you change your oil and clean the filter. This imo is the best way to catch a problem early.. These type filters are used in aviation and have significant advantages over unknown quality paper filters. They pay for themselves and will last way longer than your bike. My 2012 SG with 50k is on it's 15th oil change so my Flo filter has more than paid for itself while providing cleaner, cooler oil to my 103.
Very interesting I thought they were snake oil for the longest time, that’s awesome I had no clue about their history
Hi 👋, sorry I forgot to mention great territorial very interesting though I’ve already had mine done, ride safe,
PHIL FROM THE DARK SIDE OF THE MOULIN FRANCE.
RIP HD, Inc 1903-1999
Lmfao so true haha I loved my sportster
This is crazy. Just about the time I go to pull the trigger on a Harley-Davidson I come across a video like this and TH-cam is full of them. I've got money. I just don't feel like spending all of it and working on these bikes. I don't want to work on a bike. I want to ride on a bike!
If youcant do even minor maintenance.,and still want a Harley . Get a Evo motor they were very dependable. I have an 06 twin cam fatboy but I've had Harleys all my life ,I can deal with the minor stuff.
@@jeffhawkins711 I appreciate that comment man. I actually have my eye on a good lookin Good running 88' Evo Softail. Yeah I always have done. All my own maintenance and many repairs.
Bingo. 11:30 charging system battery, stator, rotor, regulator. The straw that broke this camel's back. Only 2 years after getting the S&S gear driven cams and the 2000 FXDX had been running like a BOOH. Thought about trading in for a new dyna but it was 2019. Got a KTM SAS w/ about 3K miles on it. I guess the dyna only sounded bad ass. May still try the recommended stator/ rotor solution someday. Thanks for the information.
I had a 02 softail custom and put 75000 miles on it and tore it down and the cam tensioners were fine. Cyco gasket tensioners
My twin cam is 19 years old and runs like a champ twin cams don't break for the hell of it usually the owner breaks them not doing maintenance doing stupid s***
This. I just got a 2005 ST Deluxe. Bike is bitchin. Take care of your shit, y'all!
Thanks for throwing this out
Thanks for the support :)
with all the upgrades my 2012 RG needs I think I should just buy a s&s motor and be done with it! Hey S&S you should start building Motorcycles put HD right outta business 😂😂
Excellent content, real world stuff.
thanks for the feedback! just trying to keep everyone riding safer longer through preventative maintenance
I have beat the absolute hell out of my Hondas, one for over 100k miles and never had to open the engines. My Harley is a pile of trash that needs rebuilt every 10k.
To make your ride safe and reliable, you need this part list: Honda, Kawa, ...😂😂
Facts Honda first
@@jon5423 I own 14 light Honda's, rental bikes for tourists. Mostly 2 up, hill roads, ... they last longer than whatever HD with car sized engines. A shame. HD copied a lot from other brands, gbut after 100 years, they still fail. Why? Only "their" made in Japan parts are reliable. I can advice them to give up that arrogant attitude and ask help in Japan or Germany... like they did before with the V Rod.
@@corneilcorneil so with you couldn’t have put it better
Great info...you so chill.I almost pass out.
Information regurgitation.
This is exactly why I don’t ride a Harley.
My 07' Dyna lowrider is my last Harley like ah old clock to fix you replace the spring. , so have about 4-grand put away
I have a 2017 Heritage 24k miles
What do I need to be aware of??
I would just take care of tensioners, primary and cam chain, being that new I hope 🤞 she treats you right, awesome ride 🏍️ 💨
people on their phone behind you.
So sell my twin cam and buy a Goldwing is what I’m hearing 😂
LOL you have just doubled the price of the bike. Never did anything on my Goldwing but tires and oil even at 100,000 miles. I have an Ultra as well. use the money I save on the wing to put in the Harley! safe riding..
I should have kept my Sportster. Now I realize when I bought my new 2004 Heritage ST. I was buying short term running junk. This will be my last HD. __ em!!!!🤬
If your 2011 or newer Twin Cam has been regularly serviced with a premium 20 w 50 synthetic oil and quality filter, and has not been abused, just ride that thang. Find other chit to be concerned about. Life's too short.
Great thorough stuff thank you. A video to save for sure
Much obliged I’m glad you found value just tried to spit out what I know selling parts for 3 years. Thank you so much for the kind words
Great video, lots of good info here.
One critique. The audio quality is poor. The music overrides your voice in some sections. Your voice cadence. Your voice is monotonous, somewhat difficult to follow, and almost sounds computer generated.
Again, good video, thanks.
Great video man! very usefull! Greats from México!
And people are still complaining about the shovel and maybe they are a Harley lovers bike but a gear drive 80 cube Evo well they are the way to go and im sorry but these engines are super fast wearing engines, I have a U.L side valve and yes I changed the head gaskets twice and its not rocket fast but I never really bought a Harley for going fast I actually would own a Japanese technology bike if I wanted 1500 cc and sorry but Harley is losing many.
@@jon5423 not to mention the price and reliability I have a buddy in Canada who has both but he prefers the Indian for economy and tourqe.
Get a hydraulic primary tensioner, thank me later.
I did ; shifts like butter now . New diamond chain after that hd auto tensioner. 😁
Good video but lose the music next video.
Turn off the choke! - Evo riders to their buddy on a 07 Street Glide while waiting for the green light 🤣
I have an 02 tc,cam tensioners were replaced five years ago currently have 41k bike runs strong but I’m beginning to see oil in the breather what would you suggest thanks
Breather filter may be saturated. Just a guess.
Owner of a 2005 Dyna, originally 88, now big bored to 100ci. This has been the worst bike ever. Unreliable pieces of junk Harley’s are. I’ve spent 8k in my motor. Dark horse crankshaft (stock one had 45 THOUSANDTHS RUNOUT), S&S big bore, SE cams, fueling cam plate, pump, breathers, injectors, and so much more which I’m not going to discuss. Do not buy a Harley whoever reads this comment. They sound great, look great, but if you really want to start hating motorcycles, own a Harley for a week.
Got a deal on a 2008 FLHRCI with cams and bars and full legends suspension etc .. was great until got an inner primary leak .. that turned out to be a blown compensator that blew the clutch assembly and a tranny bearing .. not such a good deal now
My 2023 RG 124 got some lifters getting old .. put 26k miles on that bike in one year .. not gentle miles .. prob gonna put up the loot to bulletproof the road glide from the bottom up. I need a 100k mi motor with the miles I ride
10 seconds into the video, I figured if you sounded bored with it, it must be boring so I didn't bother watching any further.
And of course, I won't bother watching any of your other videos...
Harley cuts corners - 😁
I agree all just a big money grab
@@jon5423 all to please stockholders anymore;
The S&s engines are just bulletproof compared. 👌👍
made it to 8:29 could not go any further.
Kawasaki Vulcans don't have those issues "/
True same with a Hondas the only issue is you have is to put oil in it and change the filter in a oil change
True. Having had a 2017 Vulcan Classic, I know. I also know it was a ride without soul.

R the twin cams that bad? I was gonna buy 2002 softail fxst for first bike
i sold parts alone for 3 years if you don't want to spend double the money on parts let alone cost of labor on a bike a sportster is the best option to get in and get out without losing money on harley if u keep it stock and buy around 3k-3500 dollars, but honda reliablity is unmatched then the other japanese bikes then the least relaible are like non maintained aprilla, ktm and ducati. unless you got thousands in disposable income i wouldnt i bought a vicotry after riding and making money on a sportster just my honest opinion i hope you do well in your journey and chase for a bike
@jon5423 thank u. Ya i had planned on starting with a Vulcan
@jon5423 so especially if it has 75k km on it and only last 2 years maintenance records i shud run then right? Due to cam tensioners maybe never being changed (instead of every 10k km/miles) cuz he said he never heard of that issue of the plastic wearing away and getting into the oil pump, also all the problems listed in the video. The bike may not have been serviced correctly maybe I shud jus buy a kawasaki or Honda. I wanted an older Harley but I haven't been able to find a good one. But I feel like everybody is gonna rot the shi7 out of me for riding a sportster cuz of the stupid stigma attached to it and not wanting to hear ppl n their stupid comments. For a beginner rider n being only 5"10 n 200 lbs heavy build prob the best bike for me to learn on. Cuz 7k canadian for that bike is apparently a good price n it appears to be in good shape, sorry I'm jus struggling with the decision cuz I like the bike. Can I tell if it has excessive oil coming out of breather bolts without disassembling parts? Thank u so much! Also for somebody who doesn't kno how to work on bike myself. This sounds like a nightmare to own.
I don't think an ST is a good first bike. They are heavy and maintenance intensive. That said, no bike is cooler in my opinion. I just picked up an 05 Deluxe. Looks like it spent its life on the showroom floor. Has 89K on it.
Changing the tensioners FOR THE FIRST TIME today.
Don't be scared. They aren't time bombs.
Can’t understand his mumbling 🇬🇧🏴💪🥸

Rubber is better then Poly any day of the week.

I was subscribed but you move to fast and though you seem to know what you're doing and talking about. I cannot follow enough to learn anything useful.
Most major problems were earlier Tc88 models and the 96 and 103. Most Tc88 motors are solid if you do the few things you mentioned with cam plate and oil pump n such. The major problems arise when people start pumping them full of juice or "beef" em up. An yes the Evo was solid and yes captain obvious (to the ones Wondering why) they discontinued it for a reason 🤩💸💹
I had enough common sense to buy a Honda gold wing, I ride problems free, I don't have the problems that Harley Davidson sell you. I don't buy junk, lesson learned if you want a high quality motorcycle don't buy a Harley.
