Difference between 106" and 107"
I am getting ready to do motor work this winter on my 15' RG and will be moving up to a 107" and replacing the heads. I have been working with Scott over at Hillside and they will be doing the work for me, I enjoy doing as much research as possible before and while engaging in the work. That said, I've been on multiple MFG's sites and see different options and some are showing 106" and 107". S&S lists 2 different kits one as a 106" and one as a 107", I would like to know for 1 what is the difference (and please don't say 1cc) 
. What type of gains do people actually see from the 107" HOT setups from S&S, their site only is showing around 105 TQ and 105 HP. I've heard many people getting 120+ with other MFG's (Hillside, Fuelmoto).
Has anyone on here done a straight S&S bolt on build? what was achieved? Don't get me wrong, I plan to have Hillside spec all of my build and do the head work but now I'm just curious.
Thanks
Pete

Scott at Hillside is a square shooter ... Confidence in him, with a recommendation based on your "goal", will result in a great build. 120+ packages will get you down the road quickly for sure but don't forget about the clutch and belt :>) Quit letting all the "horsepower hero's" skew your judgement. Good Luck

OK the difference is 1 Cubic Inch not 1cc.
If you went with the 106 S&S kit then you can bore it out later to freshen it up. With the 107 it is maxed out and no more boring.
Hillside has an excellent rep so be honest about what you want out of the build and how you ride and let them do their thing.

I have been very open and clear with Scott, we spent about 45 mins on the phone and a dozen or so emails in the last week.
He knows exactly what I want and how I ride. I just get curious, not planning on changing who or what is doing the work and the final product. I like researching almost as much as getting the work done.

If you buy a kit from say S&S you get one option, whichever set-up their engineers and marketting people decided on. If you go to a specialist shop like Scott and Hillside you get a set-up designed for your personal requirements, possibly one of several proven options they can supply. You've decided on the most personal set-up, so stop looking around, as you probably cannot do any better elsewhere and certainly won't get far spending time fishing around. Find yourself a good book to take your mind off things!

I did the S&S 106, but would have gone w/ their 107 if it was available few months before I finished my build to squeeze a bit more out of it.
Can't go wrong w/ any S&S parts you get, but you might be able to get the 106 for a great price now since their 107 is available.
Make sure to go all out and have Scott go nuts on your heads. Those are the key to the entire build.

no reason not to go 107 ... If your sending the motor out to him why not let him bore the cases and go 117/124? ... Just thinking out loud..
Tell him what you want and let him do work.. He will not disappoint.

A 107"er is probably the most common build right now and I would think the box set is just that boxed. With Scott, Kirby and most other indy's you get a well tuned personal build with tune. It's a total package heads flowed and matched to cams and matched to pistons....and a no brainer... Not dissing S&S they have been around for a long time and have proven themselves very well. Here's probably the best way to put it, S&S is a manufacturer. Local Indy's are builders..........
