Do you guys with these engine size upgrades get more vibration than the stock engine. Also, , is the factory stock bottom end strong enough over alot of miles to handle the bigger cubes?

OMG!
For $7k, you better be a helluva lot closer to 150ft/lbs of torque than 100, or you got screwed. I have less than that in my 120.
You can EASILY build a 103 or 107 for less than $3k that will make 120ft/lbs (+/-) of torque for less than $3k ~ if you use the right parts.

The Salt Lake City service manager, Parker, 801-487-4647 went this route and gets over 100 HP and a little more torque but your looking at $7,000.
If you go with 110 your looking a even biger bucks to split the cases, oil coolers, and whatever else they have to do and Parker doesn't think you get your money's worth.

Going to 110 requires cases to be split, and case boring. You can easily go to 113 for about the same money. I would re-evaluate what you have done with the 103 and see where you want to go, it will be much more cost effective.

<\\;P>\\;No additional vibes on my 120"\\;. Actually, it is smoother than stock because it has a crank that was built (including balanced ~ like dalton&rsquo;s) by the guys @ Darkhorse. Honestly, anything over a 103/107 you really want to give some thought to improving the crank. The 07 / 08 &\\;nbsp\\;are prone to "\\;sissoring"\\; as it is and when you pack a bunch more power in there, it really becomes a situation where the crank can easily become "\\;the weakest link"\\;. <\\;/P>\\;

RE: 103 vs. 110 big bore
My only point is that he should upgrade the cams and he should get the performance he need for a lot less $ than going with a 110. \\; I should have said a lot more torque, I don't have the actual numbers, but he replace the heads, throtle body, injectors and a lot of other stuff which adds up. \\; Those of you who can get 100 HP and 120 lbs of torque for $3000 need to list your parts and who does the install. \\; My 103 stage II runs just fine with the Rinehart true duals. \\;  \\;

For those who seem to be hard of hearing (or reading).
 \\;
CAMS, HEADS, HEADS, CAMS and CAMS AND HEADS!!! \\; Oh and a SERT or the like.
No need to change intakes or injectors until you get around 110 hp or so with a 103".
100+ hp / 100+ lbs isn't that tough with a 103" IF you match the components and have a good tuner.
Maybe $3000 +/- including exhaust if going from a 96". \\; Add about $700 or so if starting with an 88".
And for the SERK question as compared to a "built 95". \\; Get those lazy butt CVO cams out of there and work the heads a little and that 95 will be left behind whining and crying.

You asked so here is two builds I have done that exceed the 100/100 mark.
 \\;
03 RKC bored to 95", HTCC Pistons and HTCC Heads, TW5G cams, Rinehart true duals, stock throttle body and injectors, stock lifters and adj. pushrods. \\; Tuned with a PCIII. \\; 102 hp, 112 tq. \\; Cost less exhaust was \\;about $2k. \\; Work done by me.
 \\;
07 Ultra bored to 103", HTCC CNC heads, HTCC pistons, Woods TW 400-6 cams, SE 50mm throttle body, adj pushrods, stock lifters, \\;RB Racing Blackhole 2-1 exhaust, tuned with a DTT TCFI IID. \\; 120hp, 121tq at peak performance tune, 112hp, 118 tq tuned for everyday riding. \\; Cost,less exhaust and DTT was just over $2k, work done by me.
 \\;
The 120 I am now riding is a Headquarters top end (heads, cams, pistons, lifters), a Jims Crank reworked by Darkhorse and cases bored by same. \\; Total cost for just the engine build is just over $5k, again, assembly and build done by me. \\; I have not had mine dynoed, but PhilM is almost 130 hp and 157tq and my build is very similar, only differnce is exhaust and throttle body.
 \\;
You can build a reliable street stormer using Headquarters matched components for a 103 or 107 for about $3500 which would include labor and produce hp and tq in the 110 to 120 range depending on cams and exhaust used. \\; For $7k you should be able to have a complete 120 asembled and installed, again minus other peripherals like exhaust and tuning system.
 \\;
After building the HD builds, and a previous T-Mann build, I have learned the key is matched components and headwork done specifically to match the piston and cams. \\; Headquarters components will get you there with repeatable, consistent results. \\;

RE: 103 vs. 110 big bore
I ride with 2 guys a lot, 1st guy has Ultra with 110, 2nd guy rides a Street Gliude w/103. I have standard Ultra motor with Rhineharts and a tuner with auto learn. The 103 wins every time from dead start, rolling start or top end runs. Only thing we see to the 110 is he burns a lot more fuel than we do. \\;
