On the baggers when installing the air dam to the lower triple tree, always chase the threaded 1/4 X 20 threads with a tap before trying to install a bolt.
The powder coating from the triple tree gets into the threads and if you try to force the bolts in, they usually break off causing a bit of a problem.
