I went through the details of the FM107" kit with him and his only added recommendation was the 30T sprocket mod since I ride two-up in the mountains the majority of the time .... he was right on the money.

I'm very much leaning toward FM or Hillside. Doesn't seem like you can go wrong with either. Did you start with a 103 and ACR's and if so did you send your heads in or get exchange heads? How did they handle your ACR's?

You might want to give Frank Drago a call at Drago's Bike Works. He will talk to you for as long as you want about your build. Great guy who really knows his stuff.

Since the heads were mint with 1,500 miles and only 9 months old, I had the builder send them to FM for their Level B work instead of FM providing off the shelf heads. It took quite a while, but it was worth the wait to have my actual heads back. Honestly, I am not sure if the builder removed the ACR's or if FM removed them for the head work. A quick call to Jamie at FM could answer that question.

I took the original 103" pistons/rings, SE 254E cams, stock cams, SE adjustable pushrods, Stage 1 AC and other parts and auctioned them on Ebay to recoup some of the build cost.
