Chemicals discussions can quickly turn into a flamewar, but it's still a topic that's worth starting.
From personal experience, I can say that 2 things I swear by are:
Seafoam Motor Treatment - pretty much the only fuel additive you'll ever need. I've used it to keep the carbs in my 82 Seca spotless. It'll remove just about any amount of varnish build up, even in things that have been sitting for years.
Lucas Oil Stabilizer - Also used in my Seca, in a 10% mix, as recommended. I've noticed that it starts easier, since the oil doesn't drain off the cylinder walls as fast. Preventing dry starts is it's main use, but it made the trans shift better too. I'm using the non-synthetic since I have dino oil in the Seca now, but in the 250 when I switch it to synthetic, I'll use the synthetic version.
For the outside of the bike, I've been using Blue Magic metal polish, and I've been very impressed with how it shines up 26 year-old chrome.
