If you call Ducshop (Mark) they will go over options, prices, dyno #s, and anything else. Great folks to deal with.
Do you have the velocity stack kit? Best bang for the buck IMO. Big difference you can notice.

The cams woke my bike up ... BIG TIME. I've been very happy with them.

In order of importance, IMHO
1. Airbox & filter mods
2. Performance exhaust with DP ECU or PC (tuned)
3. lightened flywheel (2lbs)
4. Cams
5. Head porting, with oversized intake valves
6. HC pistons
7. Big bore HC pistons
8. Ceramic coated piston tops & combustion chambers

Ceramic coatings help keep the "heat" where it belongs in the combustion chamber, for better efficiency, also protects the piston crown from detonation.
I run the 100mm HC Pistal pistons from the Ducshop

I spoke to Mike from the Ducshop, I'm going to try out his velocity stacks and see how we go. should be +7-8hp if all goes well.
just a question tho, would the pistons give a better low down HP gain and than cams?

You will like the velocity stack kit!! Yes the pistons give an overall HP gain where the cams focus on a little midrange but bigger top end gain.

hmm... I'd say all of the above. joking aside, I can't add much to this thread because i just bought the ducshop hyper last week and it has ALL the engine mods. (cams/HC pistons/2-1 termi/ 100mm bore/KN velocity stack/ etc.) But I CAN say that if you go that route it is an absolute rocket... it's now more of uni-cycle than a motorcycle (can't keep front end down)
