As noted, the "overnight jerk" is quite common due to the plates adhering together, but I've never heard somebody experience it to the point where the starter won't even turn the engine over, especially if you've already "broken" the plates.
My clutch plates stick pretty good after sitting awhile, but I guess I never do my "initial" start with the bike in gear and the clutch pulled in. I always just kick it into neutral, start it and let it warm up a tad while I put my gear on. The only time I ever start it in gear is after I've already been riding it. I generally leave it in first when I park somewhere so just get on and pull the clutch and hit the starter button, but by then it hasn't been sitting for hours.
When it's been sitting, before I kick it into first I simultaneously pull in the clutch and "blip" the throttle a couple of times and it negates the "lurch" when I go into 1st.
I'm guessing if more people just got on a cold bike and did an in-gear start, the plates might drag enough to notice an effect with the starter.
My philosophy might be wrong, but I like a lot of free play for the following reasons.
The way I see it, as long as your clutch loosens everything up for smooth shifts, there is nothing to be gained from a clutch being "fully released" with a long lever pull in order to shift gears other than a tired left hand after a long day of riding and more strain on the cable. A lot of times I don't even use my clutch when shifting up in the higher gear ranges and even though I've already got almost an inch of slack, I never pull the lever all the way back to the bar: I just pull it back to where I know I'll get a shift with no grinding.
I always leave the bike in gear when I'm sitting at a red light, so even though the clutch pull on a KLR isn't that extreme, the less strain on my hand, the better.
Then again, I might be back on here in the future wondering why I've got transmission problems at rather low mileage.......
Seriously, tho, I've done this with every dual sport I've ever owned and have never had any issues.
Even though the "First Gear Lurch" is common, why put your tranny through it if you can avoid it? I would suggest when it's cold you start it in neutral then try the clutch/throttle blip before kicking it into 1st. Give it a try and see how it works out for you.
Just out of curiosity, what kind of oil do you use?
