Looking at a 17SG with a 117 kit seems hp is alittle low at 109hp here's build sheet, any help or info would be helpful, got a 07 SG now with a 103 dyno says 102hp
Tks for help
With Powervision,475 cam and exhaust I put down 106 hp. The short time I rode it with the 117 its definitely had more power...totally different animal. Numbers seem alittle low to me.
I just did the 117 CI S.E. IV upgrade to a new 2019 RGS - numbers are at 111 and 111 with the SE tuner - I asked for a pretty flat but long power band rather than a peak sweet spot. and the bike is super fast. I'm happy with the results.

I see that you have the same dip in your power band that I do with my 120 kit (I think because of our Rineharts), albeit at different RPM, because our cams and compression are different. Fuel Moto is getting 125/125 from their 117 kit. I think their compression is higher and they are running 5.5 G/sec injectors. I do agree yours is lower than it could be, but it's likely due to your component combination.
I agree with strych9 that the dip is caused by the exhaust system. While it is hard to beat the sound of Rineharts, the power does leave a little to be desired. The cam is another factor here. Since the engine is set up on 10.5:1 static compression it doesn't need a cam that is closing the intake at almost 30 degrees abdc. I know you are just considering buying this bike, but if you want more usable power I think the exhaust and possibly the cam are going to need to be changed. The stock head pipe without the cat and some better mufflers would be a decent exhaust system, if you opt for the Fullsac X pipe it would be even better although the gain may not be justified for the expense. If you like a 2:1 system there are definitely a few out there that work well. You may want to change the exhaust and then have it tuned to see where it is or if you do your own mechanic work it may be worth it to change cams also as cams are cheaper than tuning.
As for cams, I would try the TTS 150. I don't know your riding style, but if you are like most Harley touring riders torque means more to you than HP. The TTS 150 cam in that bike with a more efficient exhaust system will give you lots of torque in the 2000 - 3500 rpm range and should make decent HP in the low 120's area.
If you are looking for a high horsepower number another area you have to look at is the throttle body and injectors. If you want an engine to carry the torque out and produce HP it needs to be fed. Quite possible installing 5.5 injectors would help with this.
