    I was contemplating putting a new primary spring in my V. If I bought a pink spring or a dalton blue would that be all I needed? Just install the new spring and get the gains without further modification? If so what do I exactly get out of it in terms of power? Thanks for the help!

    I have a 2007 KFX400. I've replaced the battery, spark plug, and cleaned the carb. Problem is, it won't start with the starter. Sometimes , if I pump the throttle for a while, I can get it to go, but it acts like it's not getting fuel. If I push start it, it will start without exception, as soon...
