This track-only monster came to us in need of minor repairs. Before we detail that, however, let’s first take a moment to admire the performance modifications that have been done to this handsome machine. It’s equipped with high compression pistons, aftermarket rods, magnesium wheels, a titanium exhaust pipe, a Scott’s steering dampener, and a lithium ion battery. Also quite notable is the fact that there is no charging system present in the bike at all. This reduces the overall weight as well as altogether eliminates the need for an alternator. By eliminating the alternator, the motor doesn’t have to spin unnecessary parts and thereby allows more horsepower to the rear wheel.
Since this machine is constantly ran at high RPM’s (around 9,000), it’s no wonder why it blew the muffler off on its final lap the last time it was at the track. Running at high RPM’s combined with the inconsistent power pulses that are synonymous with V-twins results in unrelentless vibrations.
Harley riders can relate to these vibrations (and often the repairs needed to correct the consequential effects)- with many claiming that without some degree of vibration the bike is said to have ‘no soul’. Still, issues ranging from missing nuts and bolts to cracked exhaust pipes are common ailments of bikes that are prone to heavy vibrations- most commonly singles or twins.
| To re-attach the muffler, we first had to cut off about an inch of material where the existing rivet holes were. In the photo above, look at where the muffler joins the exhaust pipe. That section was shortened by an inch, and new rivet hole were drilled with an air drill. Next, we had to cut the inner baffle to the same reduced length of the outer muffler shell so that both pieces would properly fit. After reassembling, we inserted new rivets and installed the muffler back onto the motorcycle. Due to the fact that this is a track bike, we then had to safety wire the muffler mounting bracket bolt and the muffler springs. This safety step is to prevent loose parts from vibrating off the machine and onto the track.These same safety precautions are also utilized on drain plugs and fill caps to prevent fluids from spewing on the track. |
Next up, the RC was given an oil and filter change with Motul 300Z 10W40 full synthetic blend and a K&N oil filter.
Now in good health and with a doctors release note, this machine has been moved off the injured reserve list and has been cleared to rejoin the starting line-up!
