Before I start my bike, I pull the clutch in and when the engine turns over the bike jumps forward like its in gear. I retry it a couple of times and it will eventually stay still and start up. However, when I begin to back the bike out of my parking space it doesn't roll free like it should in neutral or when the clutch is engaged. Lately, the only fix I have found is just pumping the clutch a bunch of times, restarting the bike and trying to back out again. Any suggestions?

Don't take this the wrong way but I'd suggest not starting it in gear and not rolling it backwards either..

Why would I take the wrong way? The engine turns over with the clutch pulled in and it would start if I could hold the bike still but it jumps like its taking off. Either way, I have started the bike in neutral to counter the problem but when I go to start riding, the shift out of first gear is really hard. However, once the bike gets going and out of first gear, the shifts are back to normal.

I start in gear and roll backwards plenty...never had those issues.

Take a quick look half way down this thread:

It might be worth checking that the clutch switch is working

The problem is that wet clutch plates sort of stick together when the bike is off. So when you try to start the bike in gear, the starter is having to turn over not only the engine but also the clutch plates which are partially linking the engine to the transmission even though you have the clutch disengaged. Pretty much all bikes with wet clutches do this. Solution? Start the bike in neutral, and put it in neutral when pushing it around.

Plus the above information...you're putting excessive drag on the starter that doesn't need to be done.
Let your starter live a happier life, just reach down grab the shifter lever, take the trans. out of gear....let it warm up, pull the clutch lever for about the count of ten, put the trans. in gear and drive off.

Very smooth, no undue wear and tear on any parts, and doing this, the clutch will also live a somewhat happier life.

Well, although this thread educated me heavily on better use of my transmission, come to find out...my DOT 4 fluid was BONE DRY. Thanks though guys, Im sure some of it is still relevant. Im not leaving my bike in gear any more.

If it's dry, then you have a leak and subsequently, air in the system.

well, in that case there was very little in there. And, this issue has gotten progressively worse over the last 2 weeks. Because of what I know now, I will keep an eye on the fluid level for anything suspicious. I have never seen any fluid leaks on garage floor where I park it very night. Thanks for the insight.

If it's bone dry and you don't find a puddle anywhere on the floor, chances are you have an internal leak. I had this happen to me and had to replace the clutch slave cylinder.

It won't drip on the floor, because it's only going to leak while using the clutch. It could be leaking inside the cover like mentioned.

some 2010 models have suffered a loss of clutch fluid without any external leak. the seals allow fluid to leak into the clutch cover. the engine oil will not be contaminated im told by my dealer.

Sounds like perfectly normal behaviour for wet multiplate clutches. Norton Commando diaphragm clutch.....BMW Car type clutch and Vincent Rapide Semi centrifugal brake block clutches are less likely to jump forward. Wet multiplate clutches can't help it.....the stiction needs to be broken to disengage......its the design. My 1125R does it and I do not have a faulty clutch or hydraulics.
(Oh....by the way....I have owned the first three bikes mentioned above)
