Default Engine upgrade?

Since this engine is Mille-based, is it possible to put Mille cams and such in it and bump up the power?

Default Very Possible

It will be interesting to see which Aprilia bits find their way into Can-Am Spyder engines. The good news is the after market has lots of possibilities from the get-go! Note in this older article listing tweaked items (including dry sump) in the Mille:

http://www.motorcycledaily.com/25apr...milletuono.htm

"... You may be familiar with the Mille, but let's go through the specification sheet, nonetheless. The sixty degree v-twin has four valves per cylinder and double-overhead cams. It is fed by 51mm throttle bodies through an electronic fuel injection system featuring one injector per cylinder. The engine also features twin spark plugs per cylinder (for more efficient combustion) and dry sump lubrication for a more rigid and compact engine sump (a feature found on many race bikes).

Aprilia also justifiably brags about its patented vibration reduction system (sixty degree v-twins can be pretty unruly -- but this machine is silky smooth) and its carefully developed clutch (featuring "pneumatic power") to control rear wheel bounce.

The only difference between the engine in the Tuono and the engine in the Mille superbike is a slightly different intake manifold design and engine mapping. Having ridden the Mille R, the Tuono feels just as quick and, perhaps, even smoother than its superbike sibling..."

we are already there. here are a few pictures of what we are doing:


new high compression pistons and high lift cams





pistons in engine





we also have other parts including adjustable fuel pressure regulators, performance air filters, race airbox systems, big throttle bodies, stage one head porting, etc.

FanSpydertastic!!!!

Do you already do these mods on Aprilias?

Do you reprogram the ECU/install a programmable ECU?

Can you take a picture of the upgrade piston next to a stock piston for us?

Do you have a web site for your business??

here is a picture of the stock (220 miles) piston vs. our high compression forged piston:





as to the ecu, it really depends on what mods you are doing. we offer an adjustable fuel pressure regulator that allows you to modify fuel pressure. we also use an italian programmable add-on control unit but we are working on a dedicated powercommander as well. our web site is www.evoluzione.net but most of our engine performance products are not on the site.

As soon as someone comes out with a PCM re-flash that removes the speed limiter and the program that makes you push the button saying you read the instruction card, every single time you go to start the engine.
I'll buy one

What kind of gains are there to be had with doing the Pistons, Cams, Air filter, PCM and Head porting?
If we are at 106 HP now, Where would we end up?

Would I want to use the Can-Am sport exhaust pipe, Or would you recommend something else?

all of the estimates i'm giving are based on our aprilia experience since we haven't figured out a way to fit the spyder on a dyno yet. but, we expect that since we have built several aprilias that have made well over 150 hp (one race motor that made close to 170 hp) that with the stock bore hi-comp pistons, stage one heads, performance cams, race airbox and exhaust we should be at 145-150 hp (and these are conservative numbers because there is still some tuning to do). but just today we installed our new performance collector pipe and a remus powercone muffler on a customer's bike and he was just amazed how different the bike felt (much crisper throttle response and stronger mid-range pull). not to mention the looks and throaty rumble from the exhaust (we didn't even remove the "db killer" since he lives in a quite neighborhood).
