Harley-Davidson Twin Cam Engines are Under Appreciated

Harley-Davidson Twin Cam engines didn't exactly get the best welcome to the world after the Evo due some "issues". Those issues plagued the Twin Cam engine's reputation for its entire existence. Even as the years went by and the issues were corrected the Twin Cam engines were plagued by their reputation. It's not that the Harley-Davidson Twin Cam is a bad motor it's just got a bad reputation. Twin Cam engines are pretty reliable and can handle a good deal of power while still remaining reliable for many many years and miles.

What are your thoughts and luck with the Twin Cam engines?

[davidfaria]

With all that we now know about the twin cam it is potentially a bad ass motor that can produce a lot of horsepower and still be reliable. I think it’s a great motor.

[jeremyneufeld]

103HO here, last and best version. Still sounds like a Harley, too!

[Truth...]

Of the twenty three Harleys I've had over the past fifty six or so years, my TwinCam 96 has been the best so far and I ride my bikes daily.

[terryclay]

I have a 2002 88 twincam, got over a hundred thousand miles, tensioners change once, serviced regularly.
I have 96 twincam with over 90 thousand, both of them crank every time, both run very strong. 👍

[scottmagnuson]

Love the twin cam 103 runs great with 68, 000 + miles still strong as ever

[donwaltman]

I think most, not all the issues with the twin cam engine came from Harley's desire for more money. Getting rid of timkin and pressing crank's, ect

[craigkemmerzell]

I think the Twin Cam hands down is the best sounding motor Harley made I love mine 😊

[bearbergmann]

Love the TC88 in my 2001 Softail. Mild cams, pipes and tune are all I need (SE cams, Bassani Duals, Dynojet) and I will keep this rolling for a while.

[jimfischione]

I've had three: two 88s, one carbureted one fuel injected, one 103HO. Loved all of them. I still have the fuel injected 88. Never had any problems with any of them .

[johncamerota]

I've had 4 Twincams, 3 TC88's, and now a 103. All needed a little tweeking, all great motors!

[Jeffmd]

Can never go wrong with the twin cam 96 like my 07 street glide!! No cam chain tensioner issues or anything else you have to worry about in the 88. My personal opinion the twin cam 96 and the twin cam 103 are the best motors Harley has ever and will ever create!!

[travismccarty]

Love the twin cam! For all the reasons you mentioned. I have a 103 that's now a 107 and I'll never get rid of it

[HogLife]

Gix, I love my TC, the only downfall of this motor is the amount of heat it omits, crazy hot, gonna put some fans on it and see how she goes, but overall she’s been great

[beardenstephen]

2002 Fatboy, stock crankshaft with zero runout issues & Timken bearings. Mikuni HSR45 carb, 97" S&S top end, S&S fueling plate/oil pump, fueling lifters & push rods, ported stock H-D heads, S&S Cobra 2 into 1 header, S&S gear drive cams. I've been wrenching & riding on H-D's for over 50 years, this bike with the progressive shocks & engine mods is a pure joy to ride. It has earned a permanent home in my garage on reliablity alone.

I have a 2007 Road King with the 96. One of the first things I did after buying it new was change the pipes, the factory electronic ignition to a programmable one, and a better air cleaner to breathe better. It still runs like a rocket. Only use amsoil. Best Harley I ever had!

[stlchuckhd]

Original stock 96" in my 07 FLTR with 195K miles. Never been rebuilt; cam chain tensioners replaced at 160K (I still have the originals as souvenirs). Smoother running and better fuel mileage than the 103" in my 14 FLSTC with 26K. A bit easier to service than my 94 FXR with the stock original 80" Evo... I've done most of my long distance touring on the 96"

I will be buried with my twin cam. It gave me a ton of problems, but I still love it. I have since had the entire motor rebuilt using the S&S Sidewinder 110. The g-force can just about make me hurl my lunch. I kept the heads stock (because it's a touring bike!), threw a set of SE585 cams in it, and it's all good. I got screwed by the crank issue, so my cases were split, and in jumps the S&S 4 3/8 crank. Also tuned by techno-research. I just love twin cams for the exceptional sound that positively no m8 can give you. Technology? Na, you can keep it. Nothing like the visceral feel of a rowdy twin cam!

I have that exact 01 purple wide glide. At 30000 miles i went with gear drive and a fueling cam chest kit. Then had the heads redone and opened up to help keep it cool. It will outrun stage 1 103s and i would trust that bike to go from coast to coast. I love it and would take that over an m8 anyday. Just my thoughts

[jefferythayer]

Twin Cam 88B, hell yeah, I'm content. Heritage Springer 2003, bought 95 c.i. Screaming Eagle barrels/pistons, when I ordered bike, in May 2002, from Barnetts, and only recently installed them, couple thousand miles ago, for no other reason, because I retired, and had time. 82, XXX miles on bike, and am so satisfied!
