Do you have the cam mod done? Also what's your jetting? Pilot jet etc

I am not sure about the bolts as I have an 06, but doing the cam mod will make kickstarting a lot easier and also the propper jetting.

I have a GYTR kickstart on my 480cc 13.5:1 motor, and the cam mod made mine harder to start. The auto decompressor comes on too late. I always have to slowly kick mine over to just past TDC, then give it a full hard kick. Look into a YZ450F cam to ease starting.
