Hey grayracer, not busting your chops her dude but have you actually owned a bike like this? I have owned a 426 as well as a couple of 450s and the 426 was the best starting bike I have ever had. And the others were not bad. The 426 forces you to start it the way any 4 stroke prefers to be started. Kicking it from just after dead center.
Why, yes I have. Some you wouldn't have ever heard of, and some you would. I was "raised" on big British thumpers, some as large as 600cc an more. I'm familiar with every trick there is to do with a compression release.
And, if you start the YZ426 by the prescribed method
, you are kicking it from just before TDC, not just after. Moving the kick starter the 1" from the compression point that Dr. D mentions advances the piston closer to, but not past, TDC. Same as with auto decompression.
And it bump started better and any of the other 4 strokes I have had too. You just have to have your wits about you and grab that decomp lever. You hear it chug once and then you let go and you are back in business.
Ah, but you see, with AD, none of that flying-fingers manipulation is necessary. Let off the brake and let the clutch out...that's it. Much quicker than even an experienced lever operator.
Flooding is easily cleared by opening the throttle all the way and pushing through a couple of times.
I also tend not to be in a huge rush after a crash anymore, but I'm also rarely in the mood for unnecessary complications.
The "hostility" is mostly perceived, but it originates from people who belittle advocates of AD cam upgrades and the upgrade itself as having little or no merit based solely on the fact that they themselves have become comfortable with the manual system. I was too, and still am. In fact, I almost didn't buy my first YZ450 because it didn't have manual decompression. Now, however, I would never voluntarily go back to it.
