been posting on the nytro forums for a while.looking for some info on a 07 attak secondary.did a search already,but curious on how to get this thing to hold 10500 rpm on launch instad of dropping to 9500.secondary was set at 3 and 3 with a white spring.do you guys think 6 and 3 is too much preload.sled has 3000 kms and the secondary bushings are due.oh yeah,about 250 with gear on.

You need aftermarket weights. Lightening up the stock weights makes it overrev like crazy on top end; even by lightening up the inner hole(s) Try turning the tunnel shock adjuster to full hard; this helps a bit.

i was under the impression that the secondary setting will control how soon it upshifts.when i launch,it spins,gains traction,but then the rpm's are down at 9500.i thought it should pull 10500 or so all the way.i'm no clutching guy,just trying to learn.

The primary is overpowering the secondary. you have allmost no adjustment 7 definately not enuff to compensate the overshift
