Instead of a 13T/42T sprocket combination, you might consider the 14T/45T sprocket combination.
The 45T sprocket is stock for the Honda XR650L, therefore, many choices are available. I employ the Primary Drive sprockets available from Rocky Mountain ATV/MC on my XR650L. I like these sprockets very much, and they only cost $19.99.
