It ''just'' touches the pipe when the stand is down. When it's up all is fine, so this shouldn't be a problem for most people. | ||
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 fabricate a bracket to hold it in place. One example looks like this: | 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.

:Get a piece of aluminum strip about 1/8" thick and 3/4 or 1" wide. Twist the ends to align with the passenger footpeg mounting bolt on one end and the left peg bracket on the other. Thinner than 1/8" and it won't be strong enough. Thicker and you'll have problems twisting and bending it into shape. | |||
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 swingarm is fully visible. If you leave the centerstand on, it will be quite an eyesore. Totally opinion, of course. | |||
If you decide it's more trouble than it's worth to keep it, you can buy a nice [[Supporting Your Bike While Servicing|swingarm stand]] for about $70-100, which will let you do most of the maintenance the centerstand allows. The only time you'll probably still use the centerstand is when you're doing suspension work; the stand can be loosely attached temporarily with two 17mm bolts, and put back in the parts bin when the work is done. | |||
