Hi everyone. I am new to your site. I have a 06 700r that I bought used. I love this machine. My ? is I need a new rear sprocket, it has a 36t aluminum sprocket that is worn out. My ? is, is this the right size the guy put on? Has 15t front, rear sand stars, I think 20,s not sure since I just put it back in the trailer a off to the storage lot. My next ? is the controller. It has a Techlusion and settings look like 2 0 3 1. It seems to run good, beats most piped 450's. By the way I run at Glamis. Also has HMF exhaust, GYTR filter kit, lid off.
