Thanks guys.
I'm in Phx, AZ ... Desert riding with the wife and plenty of dune trips to come. I've got an old air cooled 250r trike, as well, that we use for the same purposes too. For now, the engine will stay fairly stock, I may do a cool head later, but nothing outrageous. Just trying to get the thing usable, right now. I don't want a ridiculously loud pipe either, we'll also be taking it camping occasionally. It may just come down to cheap too, I do things right, but I still like them as cheap as possible.
So, there's a good range of riding styles there... probably just a good, all around type of set up.
My phrasing may have led one to believe the airbox lid is still on... nope, don't even have it. When I went to test the bike it was barely running, so I just did a quick jaunt a few houses up and back. Paid him his G that he wanted, he handed me the airbox with K&N and the mount kit that wasn't even for that filter.
