I think I was told the drop in pistons would get about 10HP gain and an additional 15HP with the CAMS.
Hey Raptor....Ken lives near me in SoCal.
I thought that may have been the area. Thanks Sir! Good to know. I'm just s stretch down highway 5 away, so maybe Ken and I can work something out! He certainly sounds like the man to talk to. If it does happen, this is gonna be fun!
I did the 1060 kit with high (13:1) pistons on 2333 over the winter. Also bought a new exhaust system and had it ceramic coated inside and out. Running it through a Leo Vince carbon can with the baffle removed. I have had to play with fuel pressure a bit, but it runs better overall if not as smoothly as stock. I would not do cams unless you want to do a whole new tune. Last winter there were not as many options for tuning as there are now. I may do cams and head work this winter.

So I was thinking last night- yup, not sleeping (again) the old mind was wandering (again)!Anyway, I was thinking "how can I do something that is going to deliver REAL power gains, not just superficial stuff?"
Well, I came across this:
Aprilia 1060cc +3mm Big-Bore Piston Kit (AF1-1060bigbore)
![]()
Aprilia 1060cc +3mm Big-Bore Piston Kit
Complete +3mm 1060cc big-bore kit - $999.99
Requires cylinder boring and Nikasil re-plating - $450.00(you must provide 2 good cylinders, 4 week turnaround)
With larger valve pocket reliefs, these pistons were specifically designed for the new big-valve 2006-08 engines. They will also work well in all 1998 and later Rotax 1000cc engines, including all RSVR, Mille, Tuono, Falco, Futura, and CapoNord.
These pistons are the same weight as stock, so no re-balancing is required.
Piston kit contains 2 pistons with rings/circlips, 2 OEM Aprilia base gaskets, and 2 special +3mm Cometic head gaskets
I have looked into it and this kit WILL fit into the V990. Of course, there is the whole tearing down of the engine, sending your cylinders in, the 4 week turn-around and all the re-assembly afterwards. But MAN this would add some power to the package, wouldn't it? I just wonder how hard it would be to get it tuned after all that? It would be a heck of a project! :ani29:
I'm with you 1 MILLION % on this deal, I keep reading about 160hp rotax's in street bikes and it makes my mouth water. If its the same basic motor there should be no reason we can't swap parts in and also make that kind of power. If it gets to that point why not even bring on a aprilia ecm to run the motor and keep the brp on to control that rest of the stuff??
BTW: on a side note, I went over and met with the aerocharger guys a couple weeks back. I have nothing but good things to say about those guys and there operation, we ended up being there for literally 4hours looking a stuff and BS'ing. Anyways, their current kits make 6psi and have shown dyno numbers in the 140rwhp range, they claim the motors will easily hold 10-12psi. We will be installing a turbo kit on my spyder very soon "next couple of weeks" and I made it very clear, that I would be happy to test the high boost longevity. If I blow my motor it's just a reason to build better.
Alligator Alley.....Only problem is there is one way on and one way off, so you would be trapped.:gaah::gaah::gaah:I'm still looking for a place to unleash the power that I already have!!!:spyder:

I would say overall that it was worth it. The bike runs stronger, but not as smooth as before the swap. I thought about FI, but wanted to keep it simple. I bought the Spyder for something more comfortable to take the wife on than my other bikes, and I did not want to go as extreme as new turbo system. I do not want to chance putting the thing in limp mode or stalling with the wife on-board. Although I most likely did not get the same power as I could have from FI, at least it is still the basic suck, squeeze, bang, blow it was before..........just a little more of each.
Yeah, I know. I did not do any head work last winter because the advice of Ken at evoluzione was that I would not be able to get the tune right with that amount af increased flow just by playing with fuel pressure settings and octane level.
