I always like to go to Roebling Road. Well there is the humidity, the guaranteed rain showers and the fire ants from hell. But otherwise Roebling is always a good trip. This past weekend was no exception.
I tried my best to get away by 2:00 PM. I was using the little Toyota pickup to tow the trailer this weekend and knew I would not to be able to make the same pace as usual. The only thing standing in my way was a determination to get a new muffler installed on the SV.
I had already decided to stop at RJ’s Custom Piping in Raleigh, NC for the small amount of pipe fabrication needed. What neither of us expected was all the stuff Suzuki sticks inside a stock exhaust pipe that complicates things. Anyway, 3.5 Hrs after we started I left the shop with a nice looking pipe and although a couple hours behind, it was OK.

This new pipe is 304 stainless, looks good, has nice tone and is significantly lighter and smaller than most other cans. We made sure to rip all the restrictive plates out of the inside of the stock pipe before adding a big mounting collar on which to clamp the short transition pipe. RJ’s then made the transition from scratch and fit the new can perfectly. The whole time he worked with me to choose the right sizes and shapes to get the smoothest flow and installation/clearance.
Here’s a shot of the pipe after the first cut and you can see the restrictive double wall in the stock pipe. We yanked that stuff out to smooth out the passages. When you open up the pipe you will also see that the stock pipe is lined with another steel perforated inner pipe wrapped in fiberglass. All of that is noise damping, and power killing, material.

Notice the double wall
Here’s a closer photo of the finished SV650 custom exhaust.

A closer look at the custom pipe. The can itself was sourced elsewhere.
The weekend went well. After the second practice I checked my lap times and saw that I had shaved 4.2 seconds off my March 2011 times. That was pretty exciting. The GT Lights race on Saturday saw me get a pretty lame start. So I just settled down and tried to knock out good laps. By lap four the rain had started in turn two. And on the next lap two riders were down so the race was red-flagged. I finished seventh and collected a few points.
Sunday practice went a little less encouraging. I actually missed the first practice, turned some 1:29 laps in practice number two. I did have one off-course excursion. I was passing a 2-stroke machine exiting the final turn onto the front straight and just ran wide. Coursing over the grass at 100 MPH was interesting. But I got it slowed down and got back on track.
After practice I waited for six hours for my single race of the day. I got an excellent start, but the three Ducati’s lined up next to me were just enough faster to lead down into turn one. Lap after lap went by and it was just raw fun. The bike was flawless, the tires were flawless. I had all the grip I could imagine and finished the race third in class picking up a much needed 26 points to extend my lead in class.
Next race is late September at VIR followed by JenningsGP and Daytona, all within about 4 weeks of each other.
