I drove my wifes stock 2003 vmax 600. (new to us) At 40 mph runs at about 6,000 rpm and if i goose thottle goes right to 9,000 on tach. runs and accelerates great just CONCERNED ABOUT./.. HIGH REVS, IS THIS NORMAL??? My viper doesn't rev this high. V-max 600 also uses more fuel than my 700 viper?? (Only 100-200 miles on belt)

You will have to add heavier rivets to the primary weights. I think there are specs over at totallyamaha. Mine used to go right up to 10K at times, after proper set-up I got it down to 8,300. The funny thing is though no matter what I did as far as clutching or set up I had a hard time getting over 13-14 MPG. Great sled though, I sold it recently with well over 18K miles on it and it still ran like new.

thanx i'll try that, Even with her driving it ionly gets 10 mpg. Not totally concerned with gas millage, but if it gets better only a plus. Just thought it was reving high. It use to take off hard, almost stick but loosing track helped a lot. Was going to try another belt , but ther not excatally cheap if it doesnt change. I'll look into changing rivets on weights. thanx good riding to you.. I think I ginxed us all, bought two sleds last year, now we're having the worst two winters

Can you explain ruffly how to check or change wieghts on primary weights

You can remove the weights without removing the clutch, and drill out the rivets and replace them with heavier ones. Get the manual it is good to have on hand.

Can you buy weights at dealer, do you know what stock weight would be. Thats good i dont need to remove clutch, What manual is it in, owners? or clutch manual? I saw in previous forum someone says they went from 13.3 to 13.9 in outer hole,,,, does this side right?

search totallyamaha for more specifics, it has been several years since i clutched mine. My Yamaha dealer had everything that I needed for my sled, I sometimes had to order stuff but I never went aftermarket for hard parts.
