bueno, pues ya me contesto yo solo que buscando al final lo he encontrado, por si a alguien le interesa os lo pongo aki. Visto lo visto hay que cambiar media moto, asi que casi que le pongo doble escape y a correr
nstalling a Mille single exhaust system on a Falco
So
you want to fit a set of RSV pipes to your Falco ? ChazdFalco did and
originally posted this article on retrofitting a single exhaust system
from a Mille onto a Falco on the Aprilia RiderSite. It is re-printed
with additional photos by permission.
Dave, who got me onto this site after a very nice chat
at the Ally Pally on the Renegade stand earlier this year, imparted
some very useful information that I am sorta of glad I didn’t listen
to, he said , don’t do it.
Well the end of the story is that I have managed it. The grand designs
I started off with have been replaced by more practicle ones.
Ingredients:
- (1) Falco (stock)
- (1) RSV swing arm
- (1) RSV oil reservior tank
- (1) complete stock RSV exhaust system
- (1) Aprilia Titanium Race can
- (1) RSV Sachs shock (to be fitted later)
- 12-18 inches 1/2” bore oil pipe
- (1) aluminium floppy disk drive rail
- (1) computer with internet access and the addresses of:
I wanted a single exhaust pipe as opposed to the twin that comes as
standard. Seemed easy enough, the engines are similar so fitting
shouldn’t be a problem.
The answer from most people at the Ally Pally was “err, don’t know ask somebody else, like them” pointing at any random stall.
Eventually I walked past the Renegade
stand and although I didn’t have the money at the time I could not walk
past without asking about the air kit, which I have still not managed
to get around to purchasing. Talking about the kit obviously brought up
the question about what exhaust would be fitted (well we were on
Renegade’s stand after all), so I brought up the conversation closing
statement
“I am thinking of fitting a complete RSV system”
Rather than finish the conversation I was told I needed to talk to this
scarey looking Scots bloke, Dave. That was cool, as I am Scots myself
it was rather a pleasure to be directed to him. More so when he started
talking. Finally after all the stalls that had blank looks on their
faces here was someone who knew things and immediately explained the
problem with the swing arm. For those who don’t know, one of the
reasons for the RSV having a banana swing arm is to bring the exhaust
system tight into the bike, due to this the Falco’s swing arm actually
makes contact with RSV collector box.
“Find the Aprilia Riders’ Site and email the American who managed to
contact Pikfee.” he entoned like Alec Guinness making up some Jedi
quest, but without the sword play and mind powers and travel to exotic
planets. This turned out to be Litre1 who supplied me with the bad
news, you need to cut the RSV pipe and reweld if you are going to use
the standard Falco swing arm or bend it to fit, but basically it
doesn’t fit as standard.
Hmm, I am not that technically competent, Litre1 was talking about
having a shop look once he had assembled the bits, I decided to go the
easy way and fit an alternative swing arm and wanted something
different so started looking at a Futura swing arm.
I quickly realised that the Futura swing arm would incur a lot of
expense since I would be looking for the wheel, brake disk and caliper,
basically the entire back end.
So began the look for a reasonably priced RSV swing arm, which had
miracously tripled in price from the day before I had the money ready
and the following day (at least that is how it felt).
After a while Cheshire Motor Cycle Salvage came up trumps with a
respectable swing arm at a good price ($100) and they also had an RSV
Sachs shock so I bought that as well.
After working out how to support the bike while dropping the swing arm
out, myself and a friend who is “a man with a van full of tools” and a
further friend swapped the swing arms in about 3 or 4 hours using
information from the Hadeler site (I thank you).
This would have been the ideal time to swap the shocks as well, but I
quickly realised that my sub frame impeded the air valve by a large
amount rather than the few mils that I had read on the various sites
that talk about swapping in the RSV Sachs shock. IsleFalco has
mentioned an Ohlins valve mod that should solve that so I am looking
around to find a local-ish firm to do the mod.
Back to the pipes then ...
Now Litre1 had done a better job of researching than I had and had
obtained an RSV oil reservoir tank as the RSV downpipes run straight
down the centre of the engine where the Falco’s kinks out to accomodate
a larger (Heavier construction?) oil tank. I got mine a tad late for
the swing arm swap so the original exhaust went onto the bike again.
The following Sunday saw the completion, with the RSV reservoir tank having arrived it nearly fitted straight on.
The top mounting point is out by about 2-3 inches but in the right
plane. A quick drill on an old aluminium floppy drive rail did the job
as a temporary fix and may even be left a the permanent fix.
The oil return pipe on the Falco sits on the top of the oil reservoir
tank on the RSV it sits at the bottom so extra pipe was needed.
Mercifully the van of many tools also contained an amount of the right
piping (completely unplanned for, just lucky), the reservoir was fitted
leaving the path free for the RSV exhaust to be fitted.
I had recently secured an Aprilia titanium race can on eBay which once
the RSV down pipes were in place, attached to reveal the last problem.
...
The whole RSV rear sub frame sits higher than the Falco’s. This is why
there is a problem with clearance on the RSV Sachs shock shrader valve
and also why the my new second-hand pipe ended up being too close to
the pillion pegs. A little modification was needed to make this fit
(mostly brute force). The final solution will be to junk the pegs and a
correct sized exhaust hanger made up to allow correct fitting of the
pipe.
Or I could have the pipe bent down a little, we are talking about needing to drop the exhaust by an inch at the most.
Refilled with oil and the bike was ready to start.
I had recently listened to an RSV with the same end can. It sounded
deep and resonant but quiet enough not to attract to much attention,
just what I was looking for actually. The one I got on eBay does not
seem to be the same. It may be that I have been used to the standard
pipes but this system just seems to be too racous however having
listened to a friend ride it up and down the street it wasn’t too bad
but it is wearing on the rider. Time to find some noise killers, I will
probably have to repack the end can as well, so will measure up when I
do that, and add them if the repacking doesn’t subdue the noise.
These engines like to breath and although I can’t really report a
huge difference in performance I have noticed the front wheel lifting
more often and a lot easier.
