A crazy idea

[Mexican]

The 998cc Spyder engine has around 100hp, the RSV Millie with the same engine has around 146hp, if it is the exact same engine, how will the Spyder react with it? I wonder if they will interchange? it is very tempting to try find out

 

[Chupaca]

Not so crazy...!!

So when will you be doing this..??opcorn:opcorn:'ing to see the reviews...does sound interesting and fun...:yes:

You forgot to mention expensive, i will do some research but it will be long time before i can atempt something like that, hope somebody beats me to it and i can copy him

Will you be able to convert the output from the new engine, to the belt drive of the Spyder? :dontknow:

 

[DrewNJ]

Yes, it works. We have a local who has already done one and currently making some improvements. I also picked up a wrecked rsvr from a friend who is scared of it with the intent of doing one as well. However, cheap unwrecked spyders are hard to come by and I'm not at the point of ripping my 12' apart.
There are a few different ways to approach it. The one I rode he swapped out the gears in the trans so he had 6 speeds but no reverse. Runs the Aprilia electronics. No nanny, no abs, etc etc. Aprilia cluster.
I've also been told that you can leave the hard parts in place and swap electronics. Again losing all the nanny abs etc.
Aprilia cluster has to be modded to fit but looked nice.
The ride is unbelievable!

I was waiting for you to get to this party... :thumbup:
Is the Spyder converted to chain drive?
Please; tell us more! :bowdown:

Engine mods

I imagine the Spyder (Rotax) engine could be easily upgraded with higher compression Pistons, head work, cams and larger injectors to add 30 or 40 horsepower. A free flow air cleaner and exhaust, and the whole project comes in at $4K. We need some baseline dyno numbers, then go from there. I am in talks with MACSHACK, an engineering concern out of Utah. A set of upgrade kits, in stages, is the concept. Stay tuned! Joe

I would be curious to know how much extra stress that would put on the transmission. If you behaved yourself I'm sure it could handle it, but I tend to misbehave on occasion.

 

[DrewNJ]

Nope, using the stock belt drive. From what I understand the output shaft he either swapped or he had a splined adapter fabbed up with the stock front pulley. I know he was talking about both but I honestly don't know which way he went.
My plan if I did one was to swap the spyder trans internals to the Aprilia case.

I knew there was somebody crazier than me out there!!:clap:

You probably should grab Drew by the ears; ask him about a zillion questions and take notes about everything that he says... :thumbup:
He's already done a bunch of research on this type of project... :clap: :2thumbs:

Its not mine and I didn't build it so I'm far from being knowledgeable on the build. I do know the owner real well and have ridden it a few times. I've picked his brain on a few aspects of the build because I'm casually considering it.
He has built a lot of pretty wild custom machines over the years. Usually he builds for the fun of building it, rides it a bit, then either parts it out, or it goes into hiding in the back of his shop. He is NOT into the forum BS and really wants no part of the "community"......some of you would say he has a bad attitude.....[emoji57] BUT, if anyone is planning on building one he is a super nice guy and has no problem sharing what he knows.

I can likely get some pics next time I'm down there, but other than seeing an Aprilia cluster recesses in the dash opening and a drag radial tire on the back you wouldn't think its any different than any other RS. Its a stealth built machine for sure.

Been there, done that.

I have a kit very similar to this in a 2008 GS Spyder. Bike halls ars... 140hp. No issues in 11,500 mls. Bike is currently for sale.

[cptjam]

Exactly!

If I did not just buy a new bike Friday, I would be all over this! What a bargain and easily worth much more! Somebody grab this deal! JMHO, Joe

YOu should tell Ann about it... she needs a toy like this! :thumbup:
