My 04 Tuono R with MTC Carbon Can

Ok YevJenko i'll keep an eye out for the info although I think i may have read others posts about them.. but feel free to send me the info and I can add it to my want list.. although the wife may say no. Perhaps I should fake a fault in the current exhaust as an excuse.. lol


To get over that dip in performance (which is there for emissions and noise testing / homologation) the two most successful mods from the Mille and Tuono are the joining of the collector box pipes and the airbox mod. I'll post up some pics of the collector mod if you're not familiar with it.
 
Here's the Gen on perfromance mods - lifted straight from the af1 post here -> What mods need to be done? '03 Tuono RSV

Performance. Purpose: to even out the torque curve, smoothen the ignition and tickle a couple of extra ponies where possible

- Gabro chip. The chip you need depends on the exhaust modification made. Collector mod or 2-2 pipes require F255. Rest goes pretty much with V2/V6 version but he'll know.
- Mille air inlet boot, i.e. the boot BEFORE the air filter under it. The Mille one has far more space vs. Tuono version. Easy to see which one you have as the Mille one is rubber and Tuono one is hard plastic
- Collector mod/ 2-2 pipes. This also helps the engine to breath better. Many ponies available in the mid range and some in the top. Collector mod means that two connecting pipes are welded on the link pipe that is between exhaust head pipes and the can itself

And here it is from the other side
collector-DSC_0158_zps125e138d.jpg
- Open lid airbox. One popular one is the EVO-kit, which basically means that you take the top half of the airbox away and seal the bottom half of the airbox against to bottom of the fuel tank thus creating more volume -> better breathing. Some people do this on their own.

More extreme performance mods. Purpose: to soil your pants when you whack the throttle

- 57 mm Throttle bodies. Breathing again but maybe best used if the heads are ported
- Using Gen2 ported heads (together witht the 57 mm throttle bodies). This is supposedly one bad *** mod. Done right you have +130 bhp on rear wheel.
- Big piston kit. Easy to understand. Best used with ported Gen2 heads and bigger TBs.

More details

The mod in the horizontal is pretty much put the pipe where you want, within reason. The vertical pipe is the one you need to be careful with, as I found out the hard way. The top joint needs to be kept low enough so that the rear cylinder header pipe can slip over the link pipe and find its home without fowling on the top joint. The bottom joint needs to be back as close to the spring clip as it can be, if it is too far forward of that clip it will fowl on the back of the frame casting.

PS. I've used 1.5 inch and 1.25 pipe and there is no performance variation with either, however, potential clearance issues on the vertical pipe are greatly lessened with the 1.25 inch pipe.

Note that Gabro does a specific chip for this collector.
 
here's one of the places I saw not to use iridium -> Need help diagnosing a problem on my T

The plugs is the first I'd change. An don't go the iridium way again, use standard copper ngk ones. The iridium are alot more sensitive. Looking at your pics it looks like the iridium pin has some brigt spot on the edge, that is typical damage I've seen numbers of times.
The edges must be razor sharp or the spark will be splitted and have less concentrated energy I would imagine. Nevertheless, ditch the iridiums, it's a waste of good money as the normal ones work just as well.​

I'll keep looking for the proper bit of info on the iridium stuff.
 
Right Yev, you've got me thinking about what I will and won't do and i'll mention later later... for the moment please note that today I decided to get acquainted with the bike and get my fingers greasy... I have replaced all 4 sparkies using the same standard NGK's that it had in it.. which tbh looked like they have done more than 1000 miles (its only about 1000-1500 miles since its 4500 mile service. So I wonder if plugs were missed.

Anyway I followed instructions to raise the tank, remove the top of the airbox, removed the filter and then removed the entire Air box and the funny snorkel thingy (air inlet boot ?) at the front and gave them all a good clean and degrease. The air inlet boot seemed to be thing plastic in the main and then the arms were a bit rubbery.. is that the standard Tuono jobbie ?

After changing the plugs I paid more attention to the air filter and the airbox and I looked out for restricters... infact I couldnt find one even when using some of the guides such as 2000 Aprilia Falco Derestriction I was looking for some kind of ring or grommet that reduces the size of the hole to an inch ish... the hole is prob 2 inches plus (see photo attached) Also, at the bottom of the airbox where the filter sits there isnt much there at all so wonder if it perhaps even has a longer than normal airfilter.... as to me it looks like the bad boy previous owner has already messed around with it. Ive added some photos of the airbox and filter etc..... can you and other readers take a look and let me know if this looks standard or looks like it has been fettled with already.. i reckon the latter !?!?

Also, I had a quick look at the wiring at the back of the electric cpu or whatever it is that is between the front and rear seats. I note that there is a blue wire that has been cut and taped up both ends.. is this normal. Is this the wire that some people cut or modify ?

In terms of performance mods.. I think for now I will leave the MTC can on it, remove the rectrictor from the air box (although Im sure this is already done.. please confirm) and then get Gabro or Force Aprilia do me a chip based on these two mods. I may consider the collector in the future but for now ive spent enough on bike, holiday and blasted house so need to look after the pennies.

So, after all this waffling..here are the photo's... please take a look and let me know what you think... comments and advice massively appreciated.

INSIDE OF TOP OF AIR BOX... looks normal ???

BLUE CUT WIRE..

No idea about the airbox mod soz. if some of the wiser folks on here can't help you out, try on the af1 forum.

that wire could be the performance mod, or a fix for a dodgy tip over sensor. looking on the wiring diagram in the workshop manual there is an output from about that connector to the tip over sensor but my copy of the diag is too small to see the colour code (doh!)

(item 2 is the tip over sensor)
 
Looks like it's going out of pin 7 in this pic
connetore-b.jpg
which has a blue wire with green stripe green [B = blue v = green (verde)].

That connects to the fall sensor
fall-sesnor.jpg
and earth and switches etc...

there's a wiring diagram in the owners manual. if you need electronic copies of these two docs, let em know via PM and i'll email them to you.
