That is likely your problem. These high strung 450's need frequent valve adjustments to stay in spec. Once they start to wear in a bit and get out of spec you will get hard starting.

If you want to do it yourself, buy a shop manual for it and/or find someone to walk you through it. There are plenty of online resources dedicated to the 450R Honda, you should be able to find a step by step on one of those as well. Otherwise take it to a shop, it should cost you about 1 to 1.5 hours labor.
