I want to try the xm 805 drive belt next year,this drive belt should drop 300-400 rpm.My shift rpm is 10600 with Supertips and orn-pnk-orn spring.
no more weight to remove from the middle . and tip washer so here the question.

How much more rpm should i expect if i change my primary spring for a orn-sil-orn?
 

As Turk said

The OSO isnt going to help you other than rising the engagement rpm all so little. The diff is so small. Try removing 1washer in the tip of the weight.

Thank for the info guy's.

I could put the white spring but i don't want to got that route because of lost efficiency so maybe i should try those dalton dpyr 62 gram weigh?
 
If you are out of washers on the tip and middle, you could just shave a little weight off the weights' tips. You would only have to weight them to match them all up and cut in the same place on each.
