Review on Complete Yamaha Motorcycle Ignition Switch & Fuel Cap Set with Seat Lock and 2 Keys - Fits YFZ1000 R1 2007-2011, YFZ600 R6 2006-2011 by Jeremy Adams

The product description states that these parts must be compatible with my type of bike. However, the spark plug is about 1 1/2 inches shorter, the mounting bolts under the ignition lock are misaligned to attach it properly, and the seat lock does not match the factory parts. The mechanic I hired to replace the parts was able to get the ignition working, replaced the gas cap (which fit perfectly), but couldn't replace the seat lock. So now I have to use 2 separate sets of keys on my bike: one set for the gas cap and ignition, while another set should be used for the seat lock. My bike works fine now and that's all that matters to me.
