Question for those that have upgraded from 88 to 95 (or from 96 to 103)

Any change in cruising speed vibration? I'm wondering if they have changed those counter balancers to compinsate for the larger pistons and longer stroke for the 96" models.

I'm considering the 95" kit for my 2000. I would just like some input as far as any down side, like vibration. I would probably also change to geardrive cams. And a Mikuni 42.

I appreciate any input.

 

I have the 96B motor and was thinking of going to 103. I was concerned about the vibration also. I was also wondering if I would be creating more heat problems with the cylinders bored out to 103

 

Give Hillside Machine a call. Scott did mine this winter and very happy. Should have done this earlier. Smoother running, engine temp down, great torq. All good here. No more vibration than when stock. Maybe less. Happy riding.

 

I had Reaper's 88" B engine punched out to 95" (@ 10.5:1 compression) this winter, and I have noticed no additional vibration. I'm still breaking it in, too.

Cheers!

The SE kits specifically state that no re-balancing is required so that would indicate to me that there would not be additional vibration. Some of the aftermarket kits like HQ, etc (might) run into some vibration but if they are kit setups they most likely have been tested as well.

I think where you might run into issues is if you were to go with an a-la-carte build where you picked your own combination of pieces parts to do your build. Some combinations could create different harmonic freqs at specific or ranges of RPM's that could create noise and/or vibration. It's really hard to say though. You really won't know 100% for sure unless you build it.

 

I have an '07 Deuce and went from a 96 to 103 and have not had any issues with vibration. It's been nothing but great.

 

I have an '07 Softail Standard that I had bumped from 96" to 103". No problems so far, and I've noticed no additional vibration.

 

96"-103" Best mod !
No additional vibration except the wind at 135MPH

 

i dont feel any vibration at all...i had this bike upgraded to the 103 from day 1, my last softail model was a 00 heritage.

 

Took my 88 B to a 95 B. She got cylinders, pistions, and cams. No new balancer. No noticeable increase or decrease from the vibe that was already there. She is an 03 carbed model.
