I sent you a pm.. You will get more power. Some things in your motor will be worn. Better to have it fixed now then if it grenades making the cost alot more later on..

IMO, it's not worth it, but it is in the same sense. Over stock it's a definate upgrade and needed but I'd say to just stroke the crank and rebuild it yourself w/more power. I have a 450cc stroked Dale engine w/440 piston and a 450cc ATK engine w/stock stroke and 450 piston. The stroker easily pumps more power out, revs faster, and has a much broader and long lasting powerband for a fraction of the cost. That is if you build it yourself.

I would not touch it till it needs it! Then do as Psychois said, the big changes that ATK made were to reduce the noise and that is really not that big a deal. I would take a close look at the crank though.
