best / most reliable engine from 2001 to 2017

Fact.
The twin cam engines are cheaper to manufacture than the EVO engines.
Chain and sprockets driving the twin cams versus hardened and ground gears that come in various sizes for both the cam gear and pinion. Cheap straight roller bearing on the crank shaft drive versus tapered Timken bearings with a ground spacer for fine adjustment. (No Wet Sumping due to crank run-out so bad that it foams and the oil and cavitates in the oil pump.
Cheap pot metal Oil pump and cam support plate versus four gear cast aluminum oil pump.
No replaceable lifter blocks...Should I go on...
Just look at the recalls between the two engines...Not to mention the "Single Cam" M8's and that new Revolution thing they just came out with...
Twinkie = cheap
Even junk *bay EVO's cost more than twinks....

Not completely untrue either (6 year old thread too). I think the twinkie is a great engine that doesn't suffer from oil leaks like the evo does such as through the stator plug and cylinder base gaskets with pulled base studs. The Evo had a crappy period too where the cases were thin and prone to breaking not to mention the goofy way they mount the engine to the trans that no doubt would flex. People point to the cam chain tensioners on the twinkie. My 06 Electra-glide had the tensioners done at 80k miles as preventative maintenance and thats it. Same compensator, zero trans problems, no leaks. I've had an Evo and there's no way I would seek one out when the twinkie does it all. My 06 doesn't have ABS or throttle by wire, just EFi and Im happy to have that too since its dead reliable.
Build a cheap frame without a down tube and you have to bolt the transmission to the engine....(Think Sportster....)
I'm happy you're happy with your 06 but it's a throwaway.... NOBODY will covet it like a Blockhead, Shovel, Pan, Knuckle or Flathead.....it's just a fact.

If you didn't let the engine warm up and allow the cylinders to grow and compress the gaskets you could develop leaks. Mostly it was a problem caused by those that whipped the throttle on a cold engine....(You know who you are...Smiles)

Cons of the 07 twin cam 96, the 6 speed transmission, the gears are too tall, I had to put a Sportster rear pulley on my Road King to make the Transmission and the rest of the bike work together. Also I had to have my transmission rebuilt at about 57000 miles, because of the **** poor stock bearings.

Last year of timken bearing. I think crank changed a year or two later.
