Does this idle make sense?
Start the bike cold and it goes into it's high rpm startup idle for a few moments, rev it and it idles back down to 1300-1500 which I assume is normal idle...after I've been riding for a bit and I come to a stop light etc whatever, the bike idle is like 1500-1800????
If anything I would expect the idle after the bike has been running for a bit to be lower
Ideas?
What is the ideal ideal while waiting at a stoplight etc?

RE: Does this idle make sense?
Mine varies a bit for no good reason. It cold starts fine (2500 -> 2000 -> 1500), but warm start (> 100 degrees) it'll start straight at 1200 rpm which is sometimes a bit rough. Then after riding around for a while it'll hang at like 1500 rpm.
But this is the nature of open loop fuel injection. It's imprecise. The bike is trying to guess how much fuel is needed based on air mass and engine temperature. Cars have O2 sensors in the exhaust system to close the loop and give you that perfectly steady idle.
