Getting walked on
So I went ahead and decided to do a little motor work to my bike nothing extreme, I just wanted a little more power to beat my buddy that has a 15 SGS 103 with Tman 555 torqster cams that is it in the motor stock HG, full sac x pipe exhaust he makes 96/114.
I called TR and told him what I wanted to achieve he gave me his advice and I took it great guy to deal with btw! So anyways I went ahead and did high comp JE pistons 10.5-1 3.3cc dome volume, .040HG Tman 600sm cams, I went in and cleaned the heads up some and the throttle body as well, stayed stock size valves fuelmoto x pipe header. My compression is about 10.3-10.4 which TR said would be fine with the cams.
Now I've ran my bike through the HD race tuner data logging and autotune feature 3 times now each time the bike seems to ran a little bit better/different. I turned the throttle up a .2% as well.
Needless to say my buddy has just cams is pulling on me pretty hard 40-100 hes about 3 bikes ahead of me.
Now what can I do should I take my bike to get tuned better somewhere with a dyno or should I just say f**k it and have a 107 with heads built this winter by Scott or Kirby. I would like to keep my 600sm cams that I have now I really like the power delivery of them. I tried to be cheap the first time around and I guess now I'm paying for it being slower haha

But, a 117" with our Stage IV Heads and a Wood 9B, would end your quest......

What is the average cost of a 117 with machine, crank work and timken bearing, cams and lifters I have decent lifters but I don't think they could handle anymore then what I have now. I would like to keep a stock looking cylinder so no one knows.
Get the motor tuned. I run an all bore 107" motor in a carbed '02 FLHT with a set of decent heads, same compression as you and TMan's 600SM cams; 124TQ/110HP and I doubt that your buddy could hang with me. No disrespect but aside from a proper tune, what is the weight difference between you and your buddy? The NHRA keeps penalizing the HD team by adding more weight but the team keeps figuring out how to win in spite of the penalty. Winning a drag race has a lot to do with technique as well; knowing when to shift to keep the motor at or near peak HP/TQ is very important..........
Weight difference between him and I is about 40-50 pounds me being the fat one. I raced moto a lot of years I like to think I can shift this bike right but it could be me getting used to running this bike hard as well I went from stock to cams with a way different power output then stock. One thing I did notice is the bike feels way more ride able low rpms are more mellow and the compression braking isn't as abrupt.
If you were to do it again would you stay 107 or go 110 drop in or do a 117 along with all the extras that go along with it?!
I plan on having the bike another couple of years at least if not for awhile since its one of the last years of the twin cam, so Ill probably keep it forever

I agree with that! I have slow and fast buddies but the slow ones barley like to do the 70 mph freeway speed limit.

Stock heads are limited to about 100hp. The 555tq is a great low end grunt cam that doesn't fall off. You two probably aren't too far off from each other. I would suggest headwork and a TB. It will help the 600 grow legs and carry out on top end.
