Yamaha four-strokes are simply not hard to start. You just can't get in a big hurry and you have to follow the procedure, which isn't that precise. The problem is guys hurrying and stabbing at them like 125cc two-strokes. If you do that, they'll never run. But if you take your time and kick it properly, it's a one-kick procedure. I grew up riding thumpers and I don't have trouble starting any of them. As far as Ernie being too small to start the 250F, that's nonsense. Any woman or young kid can start a 250F if they do it right. It's like swinging a golf club, it's not a matter of size or brute strength, it's all about technique and procedure.
I agree with the previous post that suggested that Ernie return to a two-stroke. When I was a kid, we used to have a little rule for riding...if you can't start the motorcycle, you can't ride it. He obviously can't start the 250F and is too bullheaded to learn how in a race situation, so he doesn't belong on that motorcycle. I realize his machine no doubt has higher compression and less flywheel inertia than a stocker, but it shouldn't be that difficult to start. It does make for good entertainment and giggles though to watch a rider of his talent and caliber kicking his guts out and not getting anywhere. Nothing against Fonseca, I think he's a super talented rider and he does things on a motorcycle that most of us can only dream of, but I can't help but giggle when I watch him trying to start his thumper.
