|
|
Hey all.
My new machine as i fancied a total change from the fireblade.
Finally fancied doing something a bit special and not seen many of these about. It is the Factory spec model with full Sachs suspension and Brembo brakes plus a few carbon bits so i figured i may as well finish what Aprillia started.
Only bad point is the fueling is off the mark making riding at a fixed speed a chore but a rapidbike evo will sort that out.

Custom made corbin style seat.
R&G aero sliders bar ends and fork protectors.
Arrow titanium carbon exhausts (shaved about 15kgs compared to the monster that was there before).
HID conversion (a proper system which maintains beam pattern).
GPR decat.
DNA air filter.
Carbon front and rear mudguard
Carbon seat unit.
Carbon shark fin
Matte carbon tank panels and front upper mudguard (soon to be sprayed in clear coat so its all matching gloss carbon , just need to decide on the finalized decals)
Puig screen (helps immensely at anything over 80)
Scot oiler E-system because who enjoys cleaning chains haha.

I also have full luggage for it that can be fitted in 45 mins for touring use .

To be fitted over the next few weeks...
Carbon handguards, carbon bellypan (need to fabricate mounting hardware for these)
Rapidbike Evo
Pilot road 5s when the avon storms wear out.
48t rear and 520 conversion as i dont need anything more than 120 but more acceleration is always a winner.
All in all i love this bike, i know its not as full on as some of the competition but for road use i love it, and imo its one of the best looking SM style bikes on the market. ____________________ 2014 Aprillia dorsoduro 750 factory.

Improved the cosmetics a bit.
Removed and replaced most the decals and started replacing the old bolts with nice stainless A4 and titanium pieces also got the carbon handguards mounted.
I really like the look of the the bike now.

So on to dealing with the bikes running issues
The bike has now been Dynoed at Powertech. This was done to establish the baseline with factory ECU.Something i have not been able to find anywhere on the internet.
The results showed are a WOT power run.It starts off lean and then over the run balances out ok.
HOWEVER, the moment the throttle was rolled off rather than a smooth reduction in power the fueling went from 14-1 to over 18-1 causing the bike to lurch. This is exactly the issue i have had since day one when approaching corners at high speeds. The bikes fueling is FAR too conservative, especially in the lower and midrange rpm and at partial throttle.
Max power run on dyno. 79 hp and 48.8 ft ib.He did state his dyno under reads a little but im surprised it still made so much power with how bad the fueling is atm.
WOT seems like an entirely different map to the rest of it, its a mess.
https://i.imgur.com/JPMvp0th.jpg
The day was not wasted however, it confirmed several things for me.
The bikes run crazy lean stock, they are 10x worse with open cans on them.
At partial throttle, 20% 2nd gear 30ish mph it was around 18 -1 AFR which is DANGEROUSLY lean. This sort of ratio will burn the valves out over time.
If you have a DD750. Do not run it for extended periods of time with a high flow air filter decat and open exhausts. It will cause damage even with a motocorsario / fat duc fitted.
They are simply too lean from factory to be run like that.
When dynoed the bike had....
Motocorsario tuned for smooth throttle in the low range..
Dna air filter.
GPR Decat.
Arrow cans (no db killer).
The bikes making good power but its horribly delivered.Rolling on from 3K causes it to stumble and stutter its way up to 8K then it blasts to redline.
Riding with a fixed throttle at 30 MPH is impossible, you have to constantly modulate the input.
Sport mode is not usable, its simply impossible to hold any fixed speed.
The plan is...
Fitting the rapid bike evo in a few days then getting it back on dyno in about 2/3 weeks. In the mean time i have put my baffles back in to try and richen it up a little.
Arrow exhausts with baffles fitted (db killer) as i dont think there is much more power to be made without getting into high lift cams ect and i am not spending that kind of money.
Arrow Decat pipe with the 3 month old O2 sensor.
Rapid bike Evo and using its self mapping to setup.The bike will then be fine tuned on dyno using wide band sensor and manual fueling inputs.
DNA air filter
15-48T sprockets
Im also damned tempted to replace the other sensors while i am in there and keep the factory ones as spares.
Been having a play about with the software today while work is quiet .
As i read it, the flat 0 level is base factory mapping.
The Rapid bike then adds and subtracts fuel to the factory map based on feedback from the o2 sensor at the throttle position it is in.
Its not perfect but it is a self adapting map that over time gets better and better.
The idea is that each time you reach say 50% throttle the RB evo gets information as to if its lean or rich. It then adjusts the value to one in the middle, over time this repeats again and again until it has learned exactly how much the engine needs.
This is rapid bikes suggested remap for a stock bike.
https://i.imgur.com/JTIMGygh.png
Note its adding a lot in the lower range and subtracting in the higher rpms.
This suggests that in standard form the bike is massively lean up to 8500 rpm then its over fueled. My guess is that they did it this way for passing emissions tests but also to protect the engine at high rpm where a lean condition could cause it to seize.
It makes sense for a manufacturer, but its terrible for me as it makes the bike lurch about horribly.
It will be good to get these parts fitted, hopefully it will solve the issues i have been having.

So, made up some brackets to fit the belly pan today.Really tidy's the bottom of the bike up i think.
Took the bike to the local meet tonight.

Good work. It looks much better than when you purchased it. Although I did like the Umbrella Corp logo.
That being said, the aftermarket bellypan doesn't look good. I think I'm in the minority (given the apparent popularity), but I honestly don't know what they're for when there's no lower radiator. It's just a chunk of stuff that doesn't need to be there, adds weight and reduces ground clearance. For me, it's the equivalent of those awful aftermarket 'skirts' fitted to everyday cars in the 90s/00s, which hilariously feature on barryboys.co.uk.
Your post has also reminded me how much of a tedious faff it is to worry about fuelling on late model bikes. It's plain easier to leave it standard, or to fit manufacturer tuned open exhausts/filters and ECU programming (a la Ducati). Dicking around trying to make aftermarket stuff work is more effort, expense and worry than it's worth. Unless you intend to race it, then IMO just ride it as it comes. Odds are it isn't the performance bottleneck! ____________________ Current: Ducati Panigale R / Ducati Streetfighter S / Suzuki GSX-R1000 L5

Got to agree with Alex here. Starting with a bike that needs work and expense like that from new is not a road I would personally go down. But it looks well enough. Hope you get it sorted ok. ____________________ Chickenystripgeezer's Biking Life (Latest update 19/10/18) Belgium, France, Italy, Austria tour 2016 Picos de Europa, Pyrenees and French Alps tour 2017 Scotland Trip 1, now with BONUS FEATURE edit, 5/10/19, on page 2 Scotland Trip 2 Luxembourg, Black Forest, Switzerland, Vosges Trip 2017

So i have had a busy few days.
First off, the Rapid bike Evo is fitted.It took a few hours and was pretty much a direct fit to the standard loom. Only needing a wire tap in to the TPS wire.
The hardest part of the install is working out how to route the wires inside the airbox.
https://i.imgur.com/oPA1XCDh.jpg
In order to plug in the connections i had to remove the throttle bodies and injectors.
https://i.imgur.com/BBlDy6Sh.jpg
Moment of truth was starting it.
All running fine, first map uploaded and the bike is running much smoother.
First time tuning fuel injection, thus far things are going very well.
The bike pulls hard to redline with a slight flat spot around 6000 but that will be easy to tune out. This is so much easier than tuning carbs .
https://i.imgur.com/QBBbNgQh.jpg
Spent Thursday on a long ride with the mrs.Found a beautiful spot with a view over the whole of Lancashire.
https://i.imgur.com/60jHIXUh.jpg
I also swapped out the HIDs and replaced the side light with 6000K LEDs. .
Philips Luxeon Zes headlights are HIGHLY recommended . Perfect light pattern extremely bright and instant on no warm up needed.

Finished with a ride over to Beacon Fell before heading home.
https://i.imgur.com/2INI7kgh.jpg
The bike is running great, the software is easy to use and i can easily upgrade to a wide band kit and get real time tuning if i should want it.
So far i am very impressed with the auto adaptive fueling.It has totally transformed how the bike responds and made it far more enjoyable around town.
This will only improve with use as the Evo learns what the engine wants with every ride.Its already well on the way to developing its second gen remap. Really looking forward to getting more miles on it now.

So, the tuning work has begun.
Here is how my map is developing at stock (Rapid bike reccomended map for a stock bike) and 250 miles on my bike.
https://i.imgur.com/lOdH2HOh.jpg
https://i.imgur.com/f3GC8hbh.jpg
Massive amounts of fuel added at lower and midrange rpm (up to 18% more) with a large cut in the fuel at the top end.Some fuel removed from the midrange rpms at partial throttle 5/10% cruising around town.
The bike is responding well, it now pulls hard from 2000 to red line in all gears.I can roll on at 30mph in 3rd for overtakes while cruising. Before this would have lugged the engine heavily.
Will report on this again at 500 & 1000 miles.
All in all i am incredibly impressed.For £350 this is by far the best modification to do on one of these, its made the bike in to the hooligan machine i expected it to be.Even one of my friends who has the new KTM790 was impressed at how well it rides now.
The final things i want to do are clear coat the carbon, fit some light wheels and have the exhaust pipes ceramic coated satin black. ____________________ 2014 Aprillia dorsoduro 750 factory. |

Custom 48 tooth Talon sprocket arrived, 4 weeks exactly to be made plated and delivered.Fitting it and my 15T front with a DID 525 x ring next.
Clear coated matte parts with 2K in a can today. £22 a can and worked brilliantly, best clear i have used by far Touch dry in an hour and ready to be machine polished in 24 hours.
I am going to wet sand at 2K and buff it out tomorrow to remove orange peel.But i am generally very impressed with the finish.

And its finished for now.
It should have come with this gearing from the factory, top speed is around 115mph but it gets there silly fast.
I now have the awesome twisty b road bike i wanted.
Also finished the job on the bodywork with a light wet sanding then buffing.Its turned out fantastic, im properly chuffed.
After a wash

And once waxed...
https://i.imgur.com/IFTGhX9h.jpg
Now to enjoy the summer.
Winter plan is ceramic coat the exhaust pipes and light weight wheels. ____________________ 2014 Aprillia dorsoduro 750 factory. |
