Rode the black widow to my shop to remove front wheel and send it to local motorcycle shop for replacement of front tire/tube from old stock tire to Shinko sr244 that seems to be a favorite on this forum. Noticed steering felt funny and sure enough has a notchy type feeling when turn either way from straight ahead. Found Rainman's write up with pics (thanks Rainman!) in Tech section so I'll be doing that and replacing stiff fuel petcock. Spring is right around the corner so time to get the TW ready to ride!
