Hello! I own a 2003 CRF230 and am having a problem with my forks. I have found they are a little sof after riding with them with softer oil in them for a while so what oil and springs should i put in? I think i need to go harder because i'm getting bad headshake on fast sand straights and it is not feeling good. I race GNCC and am a slower rider most of the time. Any advice?
