Ok I've been thinking about doing this motor swap on my 07 SG the parts guy at my local dealer said pick this motor up and a throttle body and just bolt in but after reading everything on here it seems like there's more to it. And didn't metion anything about it not being street legal. Eric very nice and brave to tear in to a brand new create motor

80% of the guys on here have non street legal engine modifications. Unless you are in an area where emission testing is required there is no need to worry.
$8K and you can have one bad bagger.

[quote=Eric in chicago;7816352]Here is the story of my winter upgrade madness
3 months ago I started looking at doing a little engine work, I thought of going with a 107 kit but after running my spreadsheet of what I wanted to do on the build, it quickly ran up to almost 6K (dark horse crank work, head work and comp rls, SE comp, ect) I realized I could spend that same amount of money and do a 120R crate motor (I know I did not have to do all the extra work on the 107 build but I like to go overboard with reliability)
So the journey began...
I was lucky enough to find a builder/tuner that had the same idea of enhancing the 120R. Enter Jim Kennedy (StrokerJlK). Jim is a master tuner and was interested in seeing what we could pull out of a motor that was designed for the track. Our 1st step was to find a cam that would be bagger friendly, ie. moving the TQ over to the left where it is useful for touring/street driving. 3 months ago, there were very few data points on these motors, no one had takend one apart to see if these really lived up to their hype. Jim measured everything and without getting into the exact details, we found that these motors are very well put together with good SE parts.
Being in science project mode, we decided to see what we could do to make his a street friendly motor, we added S&S roller rockers, sent the heads off to WFOLarry to get cleaned up and have the valve guides replaced and normal stage 3 work done. Sent the SE 58mm throttle body off to HPI to have it cleaned up and a better flowing manifold bolted up to the TB. I decided to go with the Tman 662-1 cams as I was not concerned with HP but wanted TQ, and I wanted it early and BIG. This cam was perfect for the job. Did not have to have high compression, if fact we reduced the comp from 10.5 to 10.3, CCP came out at 190, probaly wont even need the ACR
There have been a few 120R's popping up and I am sure that more than a few will follow. I think we were one of the 1st to pull the motor apart and try some interesting new part combos. The details of the build and lots of pictures are in this thread, a good read if someone is thinking of picking up one of these motors. build details here http://www.*****************/forums/tw...ins-120rs.html
For those that ask "why tear down a crate motor, or why a race motor in a bagger" Because it is possible and it is FUN!!

Eric, WHY DONT YOU GIVE CREDIT WHERE CREDIT IS DUE! Frank at DragosBikeWorks Spec'd that 120R out for you. He told you not to waste your money on building a 107.You even told him that he was getting the work.He emailed you time and time again.You didnt even have enough common courtesy to email the guy back.Then you have the guts to give all the credit to yourself and StrokerJIK.That's totally BOGUS.
I didn't realize that I wasted my money on building a 107.

I'm going to leave the motor as it is out of the [cardboard] box.
I'm leaving the cams, and going 58 mm TB [HD].
My Heavy Breather is good, and Stock head pipe and SE Street Perf Mufflers should be alright.
We'll see what that soup tastes like... ha ha
I know there is room to grow, but somethin to work toward.
No second bike in the stable, or anytime soon now.
