Default 100 hp/ 100 tq 96?

Has anyone built one?

I am contemplating selling my stock 96 motor to help pay for a SE120R when they become more readily available, but what are some of the real-world disadvantages for having such an engine for long-haul touring or daily rider use?

I know everything exists in balance, and everything's a trade-off. More power, more heat, for one thing. But what else? Will an SE120R be as reliable and live as long as a stock 96?

I have no direct experience, but the SE120 is considered a "race only" engine, correct? If so, it may not be so easy to get set up well for touring. I would bet the cam size and high compression would make it harder to run with the varying degree of crap gas out there. I just did a run out and back from Sturgis and at the gas stations I hit in South Dakota and Iowa, on the way back, the best fuel I could get was 89 octane with 10% ethanol. Seemed to run OK but had much lower fuel mileage. Imagine that crap in a high compression 120.

By the way, I was quite impressed with my stock 96 incher on this trip. Had good power and acceleration and ran great with little heat. But I have modified the mufflers, A/C and run a FuelPak, but no other mods.

Default Yeah...

...I know I'd be content with my 96 with a cam, full exhaust system, PCV, and intake. Ya gotta admit, though, that 120'd be a bad *** motor, but I want my bike to last practically forever.

Are thunderous performance and longevity mutually exclusive in a big twin?

I installed Fuel moto's cams, exhaust, PCV and a SE intake on my 2010 Ultra and I am running @ 100 Torque and 96 HP. I still have the reliability of the of the HD motor with a little more ummph. I love the TW6-6 cams.

TW6 cams with a little more compression, pipes, breather and fuel management. I wouldn't say bolt-in, but you can do it in your driveway with a tabletop press, a few special tools and a case of beer.

John- I have read most of your recent posts concerning cam swaps and trying to better understand cam characteristics and questions on staying at 96", while also mentioning the newest 120 HD engine. You seem to be wanting some extra power [as expected :-) ], but the two subject engines are miles apart in their offerings. Also, miles apart in costs as well. If you have the dough and want billy badass- get the 120. If you want badd, try a cam swap and exhaust and intake upgrade. More badddd, get a BB Kit and compression. A little more for badass, go for heads during the upgrade(s). Set a goal (sounds like 100HP/100TQ is a target) and go for that. Also, decide what you want out of your bike- bar hopper, long trips, 2 up, loaded/unloaded, etc and go from there. Cams and compression make or break the set up. I have a 103 Stg II BB kit and 255 cams, racetuner, exhaust, and intake. When I jab the throttle, the tire lifts.... I don't think I want too much more power because I'm not really sure what I would do with it except maybe scrape the rear fender?? or keep spinning the rear tire even more...??? Oh yeah, forget about traction in the rain, two up and loaded, which isn't too fun... Good luck in your quest...

I have a TC88 bored to a 95 and turn 103hp and 102tq so I don't see why you couldn't build a stock 96 to do the same

tj316,

Do you mind telling us the specifics?
Cam, compression, AC, pipes, fuel delivery system?

I would suspect the 96 to post a little flatter torque curve due than a big bore to the longer stroke.

I'd say no . A friend has a Zipper's 107" with 130hp , 135+ pd/ft of torque . Has 20k miles on it and it's as solid as a rock . It was the whole motor , cases , and all . From what I am told , and see , a Zipper's built motor will last a very long time .
