04 450 Hard to Start

Im sure this question has been asked a bunch, but my bike is being a real pain to start. It seems to be getting worse and worse. I just replaced the plug, i tried cleaning the carb, but it is stubborn as can be. Any ideas? I just bought the bike about 4 months ago, I am used to my CR that starts on the second kick every time. Once the bike is hot, it starts really easy, but the initial start is rough. Any suggestions would be greatly appreciated.

You will hear it a hundred times check your intake valve clearances.

I was afraid someone was going to say that. Is that something that will all of a sudden get bad? The bike was starting 3 or 4 kicks for the first few months I had it, now it is more like 10 kicks to get it started, and thats on a good day. Sorry for the ignorance, just not very familiar with the motor yet. Thanks again.

Check the valves!!! Then you can at least rule them out or get ready to shim and replace etc!
