fbd,, good viewpoint thinking..

Agree now only people that have to have gear cams might have reason to rethink.

Since the newer Hyd system has proven them selfs IMO I don't know why anyone would want to install gear cams.

I used to deal with thousands of people at work and I know its hard for people to change.
But in this case I think The MoCo is taking a lot of heat for a making a change when Its actually better overall.

 

Just be sensitive to any new vibration...the counterbalance weights can shift around the crank and it will let you know. By its nature the 96b is not the preferred motor for heavy upgunning. If you don't fuxx with it much ....don't overrev or torture it...and use decent lubrication...it'll be just fine....and not vibrate at low speed like a 96 vibrate.

 

I do get some vibration at some RPM's, But nothing that Im worried about. There has been the odd burn out (2 or 3 for only a matter of seconds), and some high reving, but nothing near the red-line. I also get some slapping sounds from the primary region, and some jerking when slowing down and like a clunking.

Im not going to gear driven cams, Im more interested in the 204 kit from the MoCo.

 

My son had a 07 Duece and an 09 NT, both of them he put in the 204's, U'll love them.
Great in a light bike and have a good loppy idle.

 

Actually it's the baggers that are scissoring the wheels. That's why they came up with that goofy electronic throttle. It won't let the throttle open full until over 3000 rpm, no matter how much you twist the grip. The heavier bikes put more strain on the press fit crankpin's fit in the wheels. The low end in all Harleys has been cheapened since '03. I saw a Dyna that had the cam side main bearing walk out into the cam case. It had under 10,000 miles. The rumors of the 'B" motor being inferior to the regular motor are false. When is the last time you heard of the balancers causing a problem?

I have an '02 Fatboy with gear drives and the old forged flywheels running on double Timken bearings. It's a pretty hot 95 incher over 100hp and 100 tq. It has hauled *** for years with zero problems. Best bike I've ever owned and I've been riding Harleys for 41 years.

 

barely worth a response .. but at least you got some that called it like it is.

 

i see in the video that the moco doesn't make its own cranks.. they're made by a company called "gems".. i guess that how they spell it. at first i thought he said GM.. i about had a heart attack..

 

I just watched the beginning of the first video. The guy is saying if everything is perfect the cast iron crank is o.k.? Does this guy ride a bike?

In my day they over engineered everything by a factor of 10x. If sh*&t happens you are still o.k.

Have over 25 years machine shop inspection experience. Quality products don't cost more, just less bonus for the wall street types.



Only costs a few more penny's to make a good product. Just my 2 cts.

 

Let's see as far as I can tell there are over 500,000 to 750,000 TC96's out there. The balanced motor is identical except for the balancer.

There has only been a hand full of problems. A good % of those problems have been on modified motors.

The TC96 has hydraulic operated followers not the old type in the TC88 that had some problems for some.

My 07 FXSTC bought new in Aug. 06. Has run faultlessly with no issues.

I have two other bikes with the TC96 and they have no issues. It is not that I am lucky. It is that HD builds a good motor.

By the way having balancers improves the life of the engine. It is a rare metric bike that doesn't have balances. Shaking is hard on a motor and helps things come adrift over time. It just soaks up a little of the power but then so does the crank, cam shafts, transmission, primary drive, rear wheel drive and the rear wheel itself.

My Corvettes and Viper have harmonic balancers because it is better for the motor.

Same here on our 07, 31k and she's been perfect motor wise.. Once had a miss, turned out one of the battery cable bolts was a little loose...
