my 600 ho came from my dealer on clicker number 4, the problem is that at wot, it revs to 7500 the goes down to 7200, then slowly revs back to 7500. When i put it to position 5 it ran a constant 8300. What should i do now if i want it at 8000? my dealer told me that number 3 is the stock position, but i havent tried that yet?
