took the secondary right off - this is new to me. cleaned it all up and put it back into the holes the previous owner had marked. Sled rev to 9000 put it back into the #3 hole and the 6 hole on the plate that holds the spring in position. when i look in the service manual it says standard spring position is 3-3 where is the other 3 marking. I am taking it out after work again tonight to see if changing it back to stock will make a difference. Before it was in the #2 spot and at the same 6 mark on the cap will this still make me over rev by going back to the stock setting?

any insight would be great.

Well there is a 1,2,3 on the moveable sheave of you secondary, and there will be four holes on your helix. Mine are 0,3,6,9 but I have a 95 Vmax so my numbers might be different. In any event, that is where your numbers will be located.
 
I saw that after i posted this in the service manual - thanks for the help i will try and get it dialed in tonight.
 
So i went out after work and put it to the stock spot 3 -3 with a new yamaha belt (broke it in last weekend with about 100kms on it) and the sled will rev to well over 9 grand. changed it up to 3 - 6 brings it down but still over 9 thousand. with the exact same setting i put my spare belt back on (ultimax) and it will rev to around 8500 then sit just above 8 thousand. I am at a loss here, i have taken this thing off so many times tonight and tried just about every position with those numbers with all the exact same results. Could it just be that the previous owner did something to the primary to set it up for the ultimax belts ?
 
take a marker & draw lines from the center outward on the primary sheaves, go ride it & see how far the belt is removing the marks, should be near the top of primary. if not, it is either dirty & sticking or needs more weight. The reason it changes with the belt is probably due to changes in belt deflection- slightly different lenght belts, will change rpm's. also after running it feel the clutches to see if they are hot, if one of them is hot, your belt is slipping on that side. do these things & post back findings.

that could very well be. i know on my sleds with the clutches set up for 8500 rpm with a 8dn belt,swiching to a ultimax will lose 500-600 rpms. the 8dn is a harder compound belt thats why they last so long. the best thing to do would be find out what the primary setup is ( weights,what rivits in each hole,spring colors and roller size) to compare to the stock setup,also what helix and secondary spring is in it. sounds like the weights could have been lightened up or a higher rate spring put in. also are the clutches clean and not binding.
 
It has a green secondary spring - not sure on the hlix how do you identify it ? As for the primary the original owner said it was stock an that he stiffened the secondary so i guess it means i will be buying a clutch puller to take this whole thing apart.

I won't be able to get on it till the weekend again and i will post results then

If you're just changing weights and springs on your primary then you can leave the clutch on the motor, no need to remove it.
