Aprilia powered Chopper????

[JLF]

That bike with the in line four looks great! They usually dont look right...

Back to yours though...
Glad to see this project is moving forward!

Wow. How freakin' weird is this.

I've been lurking here for a week or so now, with these exact same thoughts. I build hot rods for a living (www.schradersspeedandstyle.com) and I have a photo of the Roland Sand KRV5 (the green one) and of the Jesse Rooke KTM powered thingy (the orange one) and an '04 RSVR that is a theft recovery sitting in one of my vendor's yards. The bike has no bodywork but nothing else is missing from it, could be mine for a song. Like less than one fifth of bluebook.

So my big questions are...what would it take to convert one of these back to carbs? And is there a dry clutch kit available for this motor or do I have to build one?

My idea right now is to keep the swingarm, motor and forks but build a tubular frame something along the lines of the KRV5 deal. Sort of a boardtrack racer-ish deal with the RSVR motor.

It doesn't help much that Shinya Kimura (http://www.zero-eng.com/) works out of the shop right next to mine...

If you can figure out a way to control the ignition (shouldn't be too hard, and there is probably enough info in mookiedog's post (here and here) to help you), you could fit carb(s) on custom intake manifold(s).

Personally I would keep the fuel injection. Much quicker and easier to plug a computer in to a PC3USB and make changes.

There is a dry clutch kit out there, can't remember who makes it, but I do remember it was quite expensive.

Sounds alot like I would like to do, so I can't wait to see what you build.

I've thought about doing that myself. Somthing low, with low, pulled back bars, a sweet cowl around the radiator, bobbed fenders, Ohlins or Penske with forged wheels. Teardrop tank with good paint but nothing gaudy. Yes, I can see it now.

Please, do it, or sell the salvage 04RSV-R to me for the conversion.

[Whopper]

I say do it to it man!!! As a former employee of American Ironhorse M/C Co. I am tired of seeing the same old cookie cutter crap. I think it would be completely badass not to mention a real pavement ripper. Please keep us posted on how its going. Would love to see the outcome.

P.S. Maybe call it the Rotax Ripper.

I am after some feedback. I was thinking about stripping my race bike to build myself a old skool bobber/chopper like these............
I figure it would be better to use my RSVR motor rather than any harley motor as the Aprilia motor has a hell of alot more horse power.
What do you guys reckon anyway? give me your thoughts.....
Cheers.

That's a great idea! I've always wanted to do something like that, I remember seeing an episode of "biker build off" where one of the guys built an old school bike using a KTM V2, really really cool!

Here is the start of the frame boys

Looks like the motor will fit nicely. Cut out the trans plate behind the motor and you have a very large space for an oil tank and possibly even a fuel tank.

Looks very sweet so far. Keep it up!

Welcome aboard Schraders!

If I was next door to Zero, I wouldnt get any work done! Please, post up some bikes if you can! Im a huge fan of theirs and got my hands on one of their rare coffee table books.

I think your project sounds like a good one... You certainly have the guys next door to go to for guidance if needed!

the title of this thread needs to be changed to - HOW TO FUCK UP ONE OF THE BEST BIKES ON THE PLANET

[Schraders]

That chopper frame is not really what I had in mind but it's interesting to see that I'm not the only sucker for punishment on out there! I couldn't find any info on a dry clutch setup anywhere on the interweb, anybody have any links? If I could see one it would be easier to make it from scratch.

The '04 RSVR I am looking at had some parts go missing last week, and the front wheel has some damage I did not notice before. So now it needs a front wheel, front rotors, calipers and both master cylinders. Plus, there are no keys. My original plan was to sell off the unused stuff (ECU, fuel injection stuff, frame, etc) and hopefully end up with what I want for next to free but I don't think that's going to happen anymore since I now need to find about $1000 worth of parts. The bike could be had for around $2-2.5k as it sits, plus tax with a salvage title. Any thoughts? They also have a few of the sport touring Aprilias, I'm not certain what the model is, sorry. They also have an '06 999R that's starting to look a lot more appealing...

JLF...Shinya has struck out on his own now and has a place called Chabott Engineering here in Azusa, CA right next to my place. Here's some of the bikes he's done recently, a genius to be certain. He just sees things differently than the rest of us. A lot of the parts and pieces on these bikes start out as junk from thrift stores and garage sales.

[William the Third]

Found the dry clutch for you. It's made by Bucci and cost $3,150. Edit: It's also unavailable, but atleast you know who makes them now.

With the aprilia/rotax v990 being a dry sump, the clutch is sort of a semi-dry as it doesn't get drug through oil but has it sprayed on it.

Just leave it injected. The throttle bodies are actually pretty appealing. A couple of tall velocity stacks and you are good to go. They don't need to be in an airbox to function. A standard Brembo front wheel can be had for pretty cheap. Same with stock clutch and brake masters. If the frame is undamaged with a salvage title is probably worth $500-$750, swingarm $200ish, fuel tank $200ish, pretty much going to need everything else.

Hey Schraders, thanks for the Shinya site and pics, this guy is doubt an artist through and through. Hey, I am sticking with injection for my bike bobber. I will having the intake manifolds made longer and bending out to one side, should increase low down power too.
