if valves need adjustment - what are the symptoms

[5th_bike]

I finally checked the valves' gaps today (first check at 1150 miles) with a Kmart (Sears) feeler gauge, and they were exactly 0.005 exhaust and 0.003 intake. No adjustment needed. I just wonder to what torque the caps' bolts need to be tightened to. Checked the spark gap too, OK. And gave it a good clean (mainly oil splatters on rear wheel). Sparkle, shine

Edit (add): oh, I couldn't get the generator cap loose - any suggestions for tools ? - so I put it in 5th gear and rolled it forward until the "T" line appeared.

I don't how a long warm up could be worse than sitting at traffic lights idling in 100 degree plus weather. I do that a lot in the summer. I would not worry about it. Once you have had the bike for awhile you will get the feel of how long it needs to warm up.
