I bought my bike less then a month ago and have been haveing problems getting it to start. Its easy to kick and sometimes you can hear it wanting to start but it takes along time to get it started. Im talking 50-100 kicks is there anything i can do to get it to start easier or anything you think i may be doing wrong to cause this?

Your best bet is to trade that heap in while you can and get a two stroke.
For us in central Missouri, the best pump fuel to use in four stroke race bikes with stock engines is Conoco/Phillips 93 octane that is labeled as "No Ethanol". Some other brands will have an identical fuel as well, but I have found that BP's 93 octane (if the station has it) does contain ethanol.
Gas mixtures vary greatly from region to region and distributor to distributor, so you can't even count on a particular brand in one area to be identical in another.
When you bought the bike did it have gas in the tank? Even though it was new (I assume it was new?) if the dealer had put in some regular gas in it to start it after assembly and then it sat there for sale for awhile before you bought it then its very likely the pilot jet is plugged or partially plugged.
Most of the 250f"s around here that I have dealt with run better if you go one size bigger on the pilot jet. If you are not good on jetting, one sign of a lean pilot circuit is popping/backfiring on de-celeration. When you have your carb off its a good idea to replace the stock fuel screw with a good aftermarket screw with the knob that you can easily reach to adjust.
