Twin Cam Harley-Davidson Engineering is it's Own Worst Enemy

Twin Cam Harley-Davidson's engineering can be it's own worst enemy. chances are if you're buying your first Harley-Davidson big twin it will be a twin cam powered motorcycle. Over all Twin Cams are pretty solid but some of the engineering in them doesn't work in favor of longevity. That's not to say you won't get the miles out of one but there are some expensive repairs you could also save yourself from along the way.

What all have you done to your Twin Cam to increase the engines longevity?

[@okinawadonkichi]

UltraCool oil cooler, Fueling high flow oil pump, get rid of catalytic converter, and a GOOD tune.

There just isn't much you can do for longevity if your gonna ride it fairly hard ! But the things you mentioned will help ! Best bet is still 99 to 02 good crankshafts & timkin bearings on the left side & a change to gear drive !

Now I need a clutch, alternator, which I Will replace when I install the race primary gearing and chain. I never had an issue with the tensioner. It is the manual adjustment one. Maybe I got lucky, I’m still happy with my Harley. 17 years of riding, basically trouble free, makes me happy!

Thank you for a great video as always. Sometimes I miss the saggy shelf, it was like a co-host. Sticking strictly to my longevity mods I replaced my tensioner shoes in my 2003 with Twin Power shoes, replaced the cam bearings with Torrington, swapped the oil pump with an S&S that tolerates run-out better than the stock pump, These bikes should have NEVER left the factory with these cranks, no left Timken, inferior cam bearings, and inferior tensioner shoes. Even if they chose to run a cam chain on the outboard side of the cam plate they should have never used a chain on the inboard side. There should have been gears on the backside. Harley is NOT the premium motorcycle they claim to be.

[@simongilbert2704]

nice one , a lot of common sense there ,, no need for water cooling on low power motors , but oil cooling = yes . here in the uk we do not get very many 'sumping' issues or overheating , the summer mornings are usually quite cool and the hot spot of the day is 1 pm , so by the time your bike starts suffering the day gets cooler ,,, [ not always ] .

[@Hoprgras]

My '06 Dyna 88inch (last yr of the 88"), shares the 96inch parts. At 10, 300 miles the Auto Tensioner destroyed my tranny bearings. Got it repaired, and replaced it with the Hayden Automatic Tensioner. But, it also has the improved Hydraulic Cam Tensioner. I now have 41,000 miles on it.

[@itchegerton8004]

At least I have an answer to why my trans main shaft bearing locked up. I put in a brand new tranny and then sold the bike. Never to get another Twin.

[@GixxerFoo]

I would say combination of crankshaft slop and overtightened primary chain by the tensioner is what did it. There wasn't anything wildly different from the 5 to 6 speed tans, on thing they changed was the primary chain tensioner. 88's had the wobbly crank later years and never tore their transmissions.

[@michaelmitchell5909]

@@GixxerFoo my 88" got 3 thou runout man...I guess I got a good one.

[@64Goef]

Besides alot of other upgrades I found that a 2" tanklift and deflectors from DK custums to increase the airflow over the engine is helping to keep the engine cooler. I don't need midframe deflectors on a hot day to keep the heat away from the inside leg. Also helps with reducing turbulance behind the fairing [2004 EG]

So, I asked him why I took the time to take my manual chain tensioner off and spend $125 for a Harley Automatic Chain Tensioner when its worse than the manual one and I still have to check it. I also asked why it takes Harley three tries minimum go get anything designed correct. I think if Harley had more and better Engineers they wouldn't need so many lawyers.

[@semperfipar1299]

Another excellent informative video. I always wondered why the primary chain was so long with that much extra length? Why did they not just shorten the chain and put a spring tensioner on it? The chain deflection alone is bad on the tensioner. There has to be a better design for a tensioner. As far as the stock oil pump? Use multi viscosity oil that pumps easily on start up like 20W50 or 10W40 4T mobil Everyone thinks thicker is better when that is not true. Amsoil. A friend of mine has a twin cam 103 and it is all stock and he puts thousands of miles on the bike without a problem. He has always put Amsoil in it.

There are no defects and unreliability have killed any resale value that they have because everyone knows if you buy one you're going to have to sink a ton of money into it to fix all of the built-in manufacturer's defect. Nevermind with the fuel injection that's a run hot as Hades. The only saving grace you can say about a twin-cam is that it is not as bad as a milwaukee-eight is. Leaking gaskets are not a big deal.

Exactly the same was said by everyone about the Evo when it was new. Everyone hated it and only the shovel (or older) was a real Harley. We even had pre-evo rallies overhere for years. Now there's a newer engine and all of a sudden the Evo is the best and the Twin Cam is bad. I'm even starting to see people saying the twincam is way better than the M8, because the M8 is not a real Harley. It never ends, bikers are worse than little kids.

Looking to replace the compensator soon, but the stock one still seems to be working fine for now. I run the speed limits and don't hot rod the bike. Other than a couple of crank sensors, I've done nothing except change the fluids on time. Bike has been super reliable

Wow, I really lucked out. ordered a 2000 FXDWG and had the dealer install the screaming eagle high flow air filter that can be cleaned and reused. The mechanic insisted it needed a rejetting in the carb due to the air filter. So, without realizing it, I got the kit that routed the oil vapor away from the air inlet and down under the bike plus richer jetting in the carb right from the dealer. They did me a huge favor. My bike now has 88,000 miles with no problems from the engine or trans. It has the five speed.

I own an 03 road king classic I've changed the cam tensioners the needle bearings and changed to hydraulic pushrods it was the 30.000 mile service at about 28.500 and just regular oil and other fluid changes at About 5000 mile intervals other than that she's completely stock

Have a 2012 Ultra Classic that had a stage 1 on it when I purchased back in April of this year. Put in a Thundermax ECM and it cooled way down. Gonna get a set of Love Jugs this spring to help if traffic gets slow. No issues with primary tensioner. Switched to Amsoil 80 miles ago.

Like your take on the mods. I'm running a S & S 110" twin cam with a Primo Rivera 3" open belt drive loaded into a 99 and under softtail frame with a 5 spd LH drive tranny. Bike is registered as 00 special construction, so there isn't much that came with it as documentation when I bought it. I'm running a Super G carb also. I have planned to add the oil cooler to the it, as I think that is the single best mod to add life to the engine, that and running AMSOIL to lube it. Any other suggestions on mods for my engine & drive train? Thanks in advance

I've got a 99 Roadking Tc 88...What Crank does it have? I just finished doing the Feuling Kit..Cams.. Hydraulic Tensioners from Feuling..the Runout was at worse 3/1000...Mechanic said that is marvelous for a bike with 40K plus miles..my question is do I need to worry about a press fit crank ?

[@brianparker3901]

Thanks.

[@danielcampbell8184]

My comments have being harsh towards the TC and they still are. You're video is spot on. What bugs the shit out of me is how good the EVO was with 200,000 miles reliability and the MOCO came out with this garbage, which are money pits. 99-06 are great after you have invested $4,000-6,000. 07-up are great after $2,000-3,000 in updates. Sorry if I hurt someone's feelings but TCs are shit, considering the price you paid when buying these motocycles. My 1980 Shovelhead and my 2000 Honda Pan European 1100 are both bullet proof.

[@mrkwnklr]

Bought a 99' Ultra with 88"A model factory demo with 9000 miles on it, only work I've done is chain tensioner pad replacement, put in adjustable pushrods. 160,000 miles no problems. Most of those miles were loaded down with gear and wife on back. I suspect though, it was tuned to get a little extra fuel being new engine. 38 mpg. You're right about the shovel, seen a few that went the distance. Rode my 62' Pan 27 years with just one top end job.

My 1981 has a rubber block style compensator (stock primary belt)... so HD knows how to do stuff but then forgets about it... have you seen the new SWM V1200, what are your thoughts ?

[@djangor4969]

When I read the title of this video, 'Twin Cam HD engineering is its own worst enemy ' , i thought that GixxerFoo was going to zero in onto the huge engineering disaster surrounding the failure of plastic cam chain tensioners built into their twin cams. He touched on it briefly but i think he failed to spell it out clearly and highlight it as one of the main problems involved in cam chain tensioner failure. If you want to get an idea of the work involved in replacing these two engine pieces do a You Tube search and you'll be convinced. Its definitely not a job for the backyard mechanic with a few spanners and a couple of hours to spare!!!

[@GixxerFoo]

It's not bad with a service manual and some mechanical experience. There were several factors ranging from the first generation of cam chains, to the spring tension being too heavy and right down to the material used. But when it got lined out with the hydraulic system and new tensioner pad material things were much better and they last upwards of 50K miles.

[@djangor4969]

@@GixxerFoo Thanks for your reply GixxerFoo. Harley Davidson may have improved on the old plastic cam chain tensioners on their more recent twin cams, but spare a thought for someone who innocently buys an old Harley twin thinking he got a bargain only to have the thing have a major engine failiure due to a cam chain tensioner failure and facing a big repair bill for an engine rebuild.

I have a tuner question for ya brother… when I bought my 07 street glide I changed the exhaust and air cleaner (already had high flow and V&H true dual long shots) I swapped to V&H big radius and went to put the V&H FP3 on it to tune it and found she already had a dynojet power commander 3… my question is which in your opinion is the better tuner? I love the real time display from the Bluetooth on the FP3 but I’ve always heard dynojet blows all the other tuners outta the water… if I go back to the PC3 can I load premade maps on it like the FP3? or does it have to be dyno tuned every time I change something? And is there an attachment i can add to it to have the real time display of temps, mph, rpm, etc… hope this makes sense cause I strongly value your opinion when it comes to this stuff!!

[@jimkillen1065]

Yea buying a used twin cam . I made that mistake from a Harley dealer a 12 street glide 103 . Checked out by service department. The crane went out in less than 1000 miles probably 500 ..so I got a SS 124 in it now that had work to the cylinder heads. I would not own a stock Harley twin cam . Yep I got a dark horse com , billet basket , chain drive , good clutch. DD exhaust ect ect money pits on both bikes . Both have SS engines. In my opinion lifters are a maintenance item , I don't wait till they fail .
