Forgot to mention.   Going to do front/rear bumpers,  air filter upgrades for sure.  wheels/tires/lift, maybe next year.  this year, just get familiar and not get to crazy with it!

Soon to receive my 950 sport. I have been watching some groups in facebook, getting my head wrapped around owning one of these things. I'm a planning type of person.  But what I dont know is what I should do first for add-ons.  Music, gotta have, but not into anything loud.  which speaker bars are good for less than $500?  I do like bass, but needing subs, old guy here!   what size O.D are the tubes for mounting things , 1.5"?    IS it ok to use regular 87 octane?  Is there any aftermarket tuning capabilities, I have a Harley and of course we have it for those, so curious if its in these things yet. I dont think I need it buuuut, you never know.   windshield(s).  will probably ride in winter, should i get the two piece so we have the lower on during the summer and both on during the winter?  just how warm/hot is it riding in these and how recommended is it to modify/close the air vent between the riders?  does it void any warranty? I planned on getting the extended warranty, but hearing some people having issues on warranty claims.  I am a pretty good wrencher myself, not afraid to replace major components. 
how bad is the winch? seems many dont like it. I dont plan on using it except to try to pull myself out of a bad situation, or someone else, but are they capable of that?   Any other thoughts, recommendations anyone want to add? I'm going to start reading others posts now!   Thanks peeps!
