Title: Harley Davidson Screaming Eagle 120 Upgrade Kit ??
Post by: Unbalanced on December 09, 2009, 03:48:13 PM
Not for 110's.

Sorry had to zip it up, it was too large for the site in raw pdf form.  4 megs.

SE 4-5/8" stroker crank. Bet this will be a challenge to keep cool in traffic! What HP/TQ does the MoCo claim for this kit? Couldn't find any info on their website. Anyone have a link?

Thanks

I see no reason this kit can't be used on 110's. After you take it apart, the cases are all the same. They need to be bored to 4.06", same as the 113 spigot holes, regardless of what size you start with. New correct length barrels are used along with new pistons. A 5/8" leg to go with it. What difference does it matter whether it started as an 88", 96" or 110"? And don't bring up the o-ring groove at the cylinder bases, because that can be worked around. Since building a real engine from these proprietary newer HD motors is the ONLY option to go bigger, there's no reason that I see why you can't start with a 110. I'd personally not bother with that combo if starting with a 110. I'd go bigger than 120, leave it 110, or go with a bigger leg and get the new 4" barrels to go with the increased stroke and not machine the cases. What am I missing here? :confused5:

The instructions say not for 110" motors.  We don't read no stinkin' instructions, right?

The instructions say that for a 113 also. It's because of the o-ring grooves for the 110 cyl bases. Like I said, you can get around that easily. Nope, don't usually need their instructions. Not for this at least. After all, this chit ain't ROCKET SCIENCE!!! ::) :) ;)

If that's true it's a sad commentary on the skills of the readership.  Having read admittedly only a little of his work I can honesty say I'd just as soon have Paul Teutel Sr. working on my bike :smash: .

i guess they've increased the interference fit between crank pin and flywheel...i'd still want mine welded

absolutely! Its is pretty dumb not to do it when the crank is out......Every new crank I have installed has gone to be welded, trued and balanced before it goes in
