Bike "Jumps" when starting on cold days

When I first start the bike in the morning on cold days, it tries to jump forward. I have to hold it in place using both legs, and the starter barely turns the motor. By the time I hit the end of the driveway, everything feels normal, and when I start it throughout the day, there is nothing out of the ordinary. I assume that the oil is a little thick because of the cold and is causing my clutch to behave badly, but I don't know if this is normal, or something I should worry about, or if there is anything I can do about it anyway.

Thinner oil would likely help (no talking oil here though that is only allowed in the Big Oil thread.)

If we knew what bike you had we might be able to suggest clutch adjustment tips.

Thick cold oil between the clutch plates will transfer power even with the clutch lever pulled. Time for an oil change to a lighter grade. Synth perhaps. Also try starting in neutral rather than just pulling in the clutch lever in gear.

No, what you describe is not "normal". It is a sign your clutch isn't releasing properly. Cold weather can make this seem worse. Starting the bike in gear with it acting like is it could result in some unintended results! I would start the bike in neutral, then pull in the clutch and put it in first. Which could still result in it lurching forward if the clutch isn't releasing. If a 650 make sure it is adjusted properly. On a 1000 it likely means either there is air in the clutch hydraulic system or the clutch slave cylinder is needing rebuilt or replaced.

Perfectly normal for a wet clutch! Every bike I have ever owned dragged it's clutch on initial start in cold weather. No adjustments needed. As mentioned, start bike in neutral, (you should be doing this anyway) and you could try using an oil with a lower first number.

Mine drags a little too. Put it in neutral and let it run for a little while. I use a 10W40 oil in Las Vegas.

Yup, normal for the Wee...starting in Neutral is always a good move. Also, move bike backwards after starting and clutch in/out before placing in 1st gear. That should prevent the "lurch" as it should force the clutch plates to unstick from each other.
No oil conversations but in the Big Oil Thread but because I have the Bridgestone BattleWings (2nd set) my clutch no longer does this!

...and hold the front brake while starting. Even if it wants to lurch, it cannot go anywhere.

I will stand by my statement that this is NOT normal!

Yes, a wet clutch can stick but every one I have been around would break loose before it got as bad as described above. Pushing a bike around in gear with the clutch in when cold will be a struggle. But nothing I have seen has ever required me to fight holding it ( I would hope a bit of front brake was in use also....) to the point it was pulling the bike along with the starter motor!
