No problem Alan,
If you are going to use a 40F0, then you will need to do some light bedtime reading and do a few minor adjustments to the carb to make it run better.
In stock trim the BST40 carb runs very lean, the fuel screw is set and covered with an EPA brass blanking plug (so the screw cannot be adjusted and the bike passes emissions tests)
This plug can be removed easily and replaced with an 'extended fuel screw' and to make the bike run better with the 40F0 as a minimum you should 'shim the needle'
All of this info is found here:
The BST-40 Bible - ADVrider
Home
So while you are shopping at Procycle you might as well add in a 'Procycle Jet Kit for stock carb'
This kit has everything you will need to remove the plug (drill bit and screw) and do this, it also contains several jets and a much better carb needle (which you should use straight away) and the extended fuel screw, so you can do much more adjustment in the future, its also IMO better than the Dynojet kit.

Anyway, don't get bogged down with all this info, Id break in your new DR in stock trim for the first few thousand miles and get used to it, then start with the Farkles
