Thanks RB. The bike came with a few little extras in the saddlebags, including a service manual. I'll admit, I was wondering how a choke could work with FI, but I guess that isn't too important at the moment. With the Seafoam, I've used it in the past on a car. In that case I used a vacuum tube to suck it into the engine, but I presume that isn't what you're think of here. Should I put it in the gas tank? I'll give the idle adjustment a tweak to see if that does any good.
I'm actually, all of a sudden, a double Nomad owner. I had a modest windfall come my way and days before this 2007 I bought a 2000 VN1500D. Then I found this 2007 and bought it and decided to give the 2000 to a relative. He had to move in with us a few years ago and has pulled more than his weight with housework and paying bills, so that's the direction I decided to go. It seem to be running fine, it's just the 2007 I'm worried about at this stage. The 2007 only has 12k miles, so it has surely seen some long stretches without rolling anywhere.
ETA, I just noticed your bike under your handle. The 2000 model sounds like a twin, same color and everything.
