Lightning Round: Harley-Davidson's hidden potholes

It's that time again! Jim Cramer rang the lightning round bell, which means he gave his take on caller favorite stocks at rapid speed:

Public Storage: "I happen to love this stock ... It was cut to neutral by Goldman at the end of the year and I said to myself this one is the great real estate investment trust baby boom play."

Exelon: "Not crazy about Exelon. I like Dominion. Exelon doesn't have the growth, but I wouldn't bother to sell it here. It's really gotten hammered already."

Seagate Technology: "I'm not selling this stock at a 7 percent yield. I'm not going to do it. I just don't think it is that bad."

Harley-Davidson: "I just saw a piece at The Street today about cash flow problems at HOG. Here is my issue with HOG, let's just be real blatant about it. The Japanese are subsidizing competition to Harley-Davidson with that weak end. And our government doesn't stand up to defend our great manufacturers. That is the problem with Harley, as it is with Polaris."

Nustar Energy: "No. I'm trying to avoid that whole high-yielding complex. I don't trust the yields."

Dover Corporation: "Oh man, people think it is an oil and gas company. When it yields more than 3 percent, that will make it an accidental high yielding stock. Let it come down a little more. If you own it I don't expect necessarily great things because it does have too much oil and gas exposure."

Scripps Networks Interactive: "Cable is so out-of-favor right now that it just doesn't really matter how good they are doing. And they are doing well. I'm reluctant to sell a stock that sells that cheaply that has that good management."
