Lowest geared sprocket set for stock 650R: 13/50

Being a woods rider on a Baja bike, I wanted to gear down right away. I found, by trial and error (got lucky) that 14/48 can be changed for 13/50 with the stock chain length - barely.

This changes the final drive ratio from 3.428 to 3.846, geared down 12% from stock but still ought to give 88 mph stock.

happy trails,
