I have to commend Samson. The system was fairly simple to install. The Nice young lady on the phone knew exactly what I needed to make for a smooth install. All parts/mounting brackets are finished nicely. There is no existing room to route a pipe between the oiltank and the motor. Samson supplies a new bracket. Unbolt the coil pack and the two bolts that hold the current bracket in place. Notice the thinner/flatter bracket. The shifter linkage was pretty striaght forward. I started the right side first. I left the plastic on the pipe until i needed to put the heat shields on. There is plenty of slack in the plastic to cut it off later and was nice knowing I was a bit safer from getting a scratch. Photo is after I got the shields on. The left side is a bit tricky. The head pipe is in two pieces. The toughest part was the rear bolt on the rear jug. I dont have a huge supply of tools but I managed to use a long extension w/ a crows foot on the end. This worked the best for me. In the end I love the look. The sound is much deeper than my TH's. Like any other I learned a few things for the next time. (i.e. the fins ARE sharp enough to cut you multiple times.) If you got any questions or wanna see more pics let me know.
