    "Works well - the shifting feels different. I didn't miss any more shifts."  Lance H.  Petaluma, CA    July 2013
     It's freggin awesome. Night and day difference.. I raced this weekend.. 4 motos and never a missed shift or false neutral  Dec 2013
  I had the new detent spring installed and also went with the Factory Pro arm - it doesn't have any slop/play like the stock unit does. Rode it today for the first time and it shifts like my 450 now. Not a single missed shift. That's the best spent mod I may have ever done,    Dec 2013

The "Midrange" Race stacks are my choice for any street and most track use.

The additional 4-5 HP across the 7000 to 9000 rpm range augments the 2 True HP gain at 10,000 rpm.
