Pop starting
If you are selling it, it would be a good idea, and a good faith measure, to put a new battery in it, or at least have the battery in it fully charged. I wouldn't start it by "popping" the clutch.
Why is the battery dead? If it's because it's a 3 years old battery, replace it.
For the ~$30 it will make the buyer happy, not the other way around.
Nothing like having to buy a new battery for something that you just bought.
Me, I wouldn't be terriblypleased.

Otherwise, just give it a good charge. As in overnight trickle, not just a drive around the block.
Jump start: using jumper cables hooked to another vehicle.
Bump Start: Back the bike up to get the piston to TDC, then with the bike in 3rd gear with the clutch pulled in, have some strong SOB, or his kids and wife push as hard as they can until you pick up speed, then dump the clutch. On lighter bikes you jump on the seat hard with your butt, which keeps the rear wheel from locking upas easily. I bump startedmy old CBR 600by myself for a whole riding season cause I was too cheap and lazy to buy a new battery.
Igot adeadbattery on my old FXR onthe way to Sturgis one year while riding alone. This dude rode with me from Chamberlain, SD to Rapid City, pushing my bike to bump start it after each gas stop. This guy was a saint. It won't hurt your bike one bit. Jump starting from another vehical can as you can get feedback to the alternator and short it out. I've jump started lots of bikes. You have to be careful with cable placement, just like jumping any other vehical. Like other posters said, test the battery. I would'nt buy your bike, without the electrical problem at least being diagnosed. If you have a 3 year old battery, its probably time to replace. Good luck with the sale of your bike.

My buddy had to get a battery for his Fatboy yesterday.
He paid $109 from an Indy.

Wow! The price of lead must've really gone through the roof.[:@]
Still (even more so)though, I think that it would be better for you to replace the battery prior to the sale than to make the buyer do it.
Maybe talk to the buyer and suggest splitting the cost.?
Take the seat off and slap a charger on it - 2 amps about6 hours, 10 amps about 35-40 minutes. Either that or go to Walmart and get a "Battery Tender" (anywhere from $18 to $30) that will trickle charge it. They come with a variety or attachments.
Take the seat off, attach the leads and put the seat back on. Fasten tender to the leads then plug it in. It will do a full charge (even @ .75-1.25 amps) overnight and you can fire her up to check for problems.
As an added bonus you get to add it into the sell and the new owner might be able to get another year or so out of that battery.
If not, just eat the $100 and stick a new battery in it ASAP. Har to believe this is even a question really unless you're selling it for rock bottom pricing and flat out of $$.
