Spark plug wire

I was having problems getting the 400ex started today so I decided to check the spark. I pulled out the plug, stuck it back in the wire and was getting a white spark as it was grounded on the block. I always thought a white spark was weak and blue was strong. I grabbed ahold of the insulator and spark plug and the whole thing pulled right off of the wire. So, I had the yellow insulator and the plug in my hand and the wire was just hanging. I wasn't sure how it went back on and ended up ruining the insulator. Do I have to buy a whole new spark plug wire or what? How much will it cost?

not sure if you need to replace the wire of not, but if you do go to www.servicehonda.com and you can get a price on the exact part you need.
