Welcome to the site :cool:
Regarding your Yamaha, I would suggest that you put a thread in the
Vintage Bikes / Racing Forum. There is great group of old farts that hang out in there that were around when the Yamaha was state of the art. :)
Although I don't exactly understand your question about pictures, check out the
What are Subscribers and SupportTeam Members? thread for information regarding what the benefits are for the various levels of membership.
If you mean avatars, all avatars used on DRN are designed by a member of the site. There is a group available to subscribers and an expanded group available to support team members.
I see you are from Michigan, for opportunities to hook up with some fellow members watch the
Michigan Trail Riders forum. There is a tremendous group of DRNers in the Michigan area.
