It's tempting during this season to jump on the bike, turn on the ignition, hit the starter and take off.
I've found that doing that will give me problems in the first 5 minutes with the engine bogging down when I hit the gas instead of taking off. Why? It's something to do with the ECU and it's warm up program that even though it's 90 out it wants to go through the process. Solution? Turn on the ignition with the bike in neutral and listen to the pump cycle. Now hit the starter and let the bike idle while you put on your half gloves. Give it about 30 seconds and take off. I've NEVER had a problem with it bogging down after doing this. Now, when (and I did it last week) I jump on the bike, hit the switch and give her the gun I can pretty much count on the bike just lolling to a stop when I'm hitting the throttle. It's kinda embarassing reaching up in the middle of a turn, pulling the clutch, killing the engine, turning the kill switch back to run and waiting for the pump to cycle then hitting the start button. But I had slung myself out around this slow poke who did NOT want to get out in the intersection at my first stop light out of work. I went to blast by her and the bike just felt like I killed the ignition till I let off the throttle. Oh, it was quite happy at idle.
I'm used to this error, I know what causes it and I know how to avoid it. Never have these problems with a carbed bike. Oh well, the engine runs nice and smooth if you treat it like I said. On the 1700's you start the bike and don't touch the throttle for at least 12 seconds. I think it's a similar program for the 900 just not as touchy.
