Have been reading a lot about how hard the YZF's are to start. I just got a '98 with a White Bros 420 kit and an E series exhaust. It could not be more easy to start. It almost always starts first kick, no choke if it's above 80 outside on the first start of the day. I went down pretty hard at Elsinore last month and when I tried to start it, I pulled out the hotstart and pulled in the comp release, ran the kickstarter through a couple of cycles, found TDC, kicked and it fired right up. Now my question is this: Does easy start translate to loss of compression and a top end rebuild? The 420 kit is just a year old. I have also started several cold 426's with no problem.
