*Installing a Muzzy requires you to lose the centerstand - you can't have the centerstand and the Muzzy.  
*Installing a Muzzy usually requires you to lose the centerstand, although see below for how you can keep it.
*You '''[[I want to improve my carburetor jetting|need to rejet]]''' and fine tune the carbs.

There are a few problems with this, however. First, the spring that holds the stand in place when retracted rubs the Muzzy's larger head pipe. It just touches the pipe when the stand is down. When it's up, all is fine.


Second, there is no "stop" for the stand anymore when retracted (since the left canister is gone); there is nothing to keep the spring from pulling the centerstand up into the swing arm and drivechain. You could possibly fabricate a bracket to hold it in place, but it would involve some skill and is not a standard mod, so there isn't much information about it.

Lastly, the Muzzy is designed to increase performance a bit, sound good, and look good. One way it looks good is by really cleaning up the back of the bike; with the stock exhaust cans gone the swing arm is fully visible. If you leave the centerstand on, it will be quite an eyesore.
