There were many reasons for the change of the site software, the biggest was security. The age of the old software also meant no server updates for certain programs. There are many benefits to the new software, one of the biggest is the mobile functionality. Ill fix up some stuff in the coming days, we'll also try to get some of the old addons back or the data imported back into the site like the garage. To create a thread or to reply with a post is basically the same as it was in the prior software. The default style of the site is light colored, but i temporarily added a darker colored style, to change you can find a link at the bottom of the site.

Ken also yanked all the VSS stuff too--- FWIW..... 
He builds and works on Aprilla's all the time--- so should know a bit about these engines......:thumbup:
I believe the key with his power upgrade is to do the cams along with the pistons........:thumbup:
He doesn't really post much on either forum, but was more than willing to answer questions when I have called him in the past.

I think I was told the drop in pistons would get about 10HP gain and an additional 15HP with the CAMS.

I would say that's a reasonable assessment, Sir. I know it'd be a major project and a lot of work (don't really know how much of it I'll end up doing to be honest!) but it would be nice to have that extra kick in the pants!
HDX, your point on tuning is one of the things I am concerned about as well. I would say a good amount of research will have to be done before I consider actually pulling the trigger on it.
Scotty, your point on ECU as well is estremely valid. May end up using a different ECU altogether! Or none at all (Evil laughter ensues!!) :roflblack:
But it's all gonna start with research. Gotta get myself edu-ma-cated first!

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 think it would be great to get to work directly with him on modding your Spyder for better performance. Kind of like when aka1004 was the test subject for Dynojet with the new Power Commander stuff for the Spyder. :thumbup:
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.
Do you have a write up and pics of this adventure?

I apologize for not reponding sooner, My Sister from Baltimore has been in town and left today. It was a great visit. Too short of course.
But now I can respond to your post. I am extrememly intrigued by your experience and would love to speak to you more about your journey, and your impressions of the results. I hope you will share a bit more with me. Or the group. The main question I have is... would you do it again knowing what you know about it now and what it has (or has not) delivered to you? Thak you for your time Sir!

So I was thinking last night- yup, not sleeping (again) the old mind was wandering (again)!
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.

That sounds cool, we could all use a good test pilot to push these things for us and see what the results are.
I was hoping for 2011 BRP would come out with a different version of the Spyder for High Performance, like they have with their water craft. If they can have 255 hp in a Sea Doo, why can't I have it on the street? I would like to see a Spyder RXT, or something similar, with extreme performance from the factory.

Looking for more power?
I'm still looking for a place to unleash the power that I already have!!!:spyder:

Alligator Alley.....Only problem is there is one way on and one way off, so you would be trapped.:gaah::gaah::gaah:

OOOOOH BABY! You are going to have to chronicle this adventure for us for sure! I am assuming we are just doing the Aerocharger and not punching out the block correct? I can't wait to hear what happens!
hyea: Good luck to you Sir!

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.

I sure appreciate your input on this. I'm still considering it; I love the idea of it but I'm kind of on the fence at this point. The options are either punch the block and message the heads or go the turbo route. GOtta weigh the pros and cons of each I suppose.
You had mentioned you were considering doing some cam/ head work this winter. You'll have to let us know if you pull the trigger on that one. The math I'm doing here would seem to suggest that doing both with complimentary componets will bring the max result. I reckon that is kind of obvious though! :roflblack: I just wonder about the tuning aspect of playing around with the top-end and the ECU etc. and how difficult that is going to be to get right.

Yes because we all know how wonderful today's fuel is... :shocked: Back in the day when I was running my '69 camaro I knew a guy who could get me Av gas and we would make a mix. Holy Shnikies, talk about go juice!
But the tune aspect I think just may be the show-stopper here. And the chatter I am getting is if anyone would know it would be ken at Evo. I mean I don't want to be like the master tuners who do the Hondas and Toyotas etc. and have to sit there with a laptop mounted just to run your bike! For me that takes all the fun out of it.
At the same time the turbo has it's own pitfalls. Waiting for the turbo to spin up is a pet peeve of mine! And the bearings wear out frequently.
I may just do what you did and go with the big-block kit. Keep it simple and make power at the core, not peripherally. Makes sense to me! :thumbup:
