My 2015 110 T/C Street Glide with 90k miles of mellow non-speeding cruising across these United States was starting to consume a little oil so I decided to send her in for a refresh to include:
1. Rebuilt Crank (Dark Horse) and replace bearing
2. Heads rebuilt and ported (Zipper’s Sport max)
3. Jugs bored out (Zipper’s)
4. New pistons (Zipper’s)
5. Replace transmission bearings
6. New cams RS-576 and bearings
7. HPI reworked Throttle body to 55mm
8. Feuling Hydraulic Lifters/ tappets #4050
9. Cam Chain Tensioners (Zipper’s)
10. Head Pipe (Bassani)
11. Spark Plugs
12. Dyno tuned
13. Compression 10.5
Had the work done by “Dyno Dave” at JD’s Cycle Works in Nazareth PA.
Originally, I was thinking about getting a 124 kit but Dave talked me out of it. He promised that he would get a performance bump out of the 110 while maintaining reliability and rideability.
As far as the performance bump, you can see the dyno before and after results. Way better than I expected.
But what really made my jeans tight was how much smoother the motor runs. At idle it seems to shake a little more than before. This was expected due to the additional overlap of the RS-576 cams over the 24D’s that were replaced. As soon as you put the throttle to it, it smooths out like butter.
At first after dropping it off, I was regretting not increasing the motor cubic inches, but after seeing the dyno sheet and riding it a couple hundred miles…….All I can say is that “Dyno Dave” is the man!
