Gee, I really don't have a choice w/my bike. Ever since I jetted it, it's semi-hard to start. You have to have the choke exactly in the 1/2 position. Full choke - no start, no choke - no start. After it starts, it's gotta run at about 2500 rpm for at least five minutes before unchoking or the engine dies. ONce it's warmed up, it runs like a top for hours on end. Anyway, warm up is extremely crucial for any motor that runs at extremely high rpm's. Two words; motor oil. You engine's blood. Even when it's 95 degrees outside (it's 97 right now in San Antonio!) your oil is still much too thick to lubricate properly. Also, it takes a few minutes for the oil to get pumped to all the vital nooks and crannies that need to be lubricated. Sit there for 5 minutes and use that time to check for nails in the tires, proper signal functioning etc. Preflighting the bike is something I do every single time the bikes been sitting for more than a few hours OR if the bike's been out of my sight. I.E. while I was inside the restaurant getting a bite to eat.
