I went to Waynoka Oklahoma today to the sand dunes and raced a stock YFZ450 5 or 6 times. I destroyed him untill we got to 5th gear at which point he could catch me and pass me. Has any one else had this happen to them? This is the first time I have been out after I installed the big three. Had it Dyno'ed last Wed. Its running just a tad under 45 hp. Also I could tell 5th gear dosent pull like the rest. Should I make a gear change? I dont spend much time in 5th gear but still pissed me off. Love the sound of my Dasa, WOW!!
