OK so I've gone and done it, I've bought a '09 RC8 R, pic below (I have posted this on another thread but it will have to do till I take some more pics)

About the bike, as described above it's a '09 RC8 R, 17k miles, full Akra system, it's just had a service, new tyres pilot powers which wouldn't be my 1st choice ((or 2nd or 3rd for that matter) but they are brand new so I'll make a decision on whether she needs stickier rubber a little later. It's also had new brake pads, SBS HS ( I'd have preferred the RS version) but again they are new so can't really moan, the forks/rear damper have just had a refresh so that's a nice bonus, chain looks reasonably new, so all in all it seems to be all good, there are a few issues though, the tank is a little rough it's sort of 1/2 satin 1/2 matt with some stains from what I'd assume is petrol spillage so I'll probably end up repainting it, the tail and belly pan plastics could do with a re-paint there are a few scratches on the tail and some heat damage on the belly pan, they are all fully serviceable but eventually I'd like to sort them out. The other cause for concern was the efi light flashing a fault code at me, 7 slow blinks 2 fast = 72, this apparently is a 2nd throttle issue/malfunction. So I've borrowed a TuneEcu off a friend, download the software and liked it up, this revealed 3 fault codes P0051 O2 ground/open circuit, P0351 no1 coil malfunction and finally P0638 2nd throttle malfunction ( my 72 code), any way I've cleared the codes and will run it up to temp tomorrow see if they return ( finger crossed). The other minor niggles is not been able to remove the little seats mount hole plug things, I've pulled at the lever but they are solid, maybe I'm doing something wrong? either way they need to come off I'm not sure if the rear plastics will come off with them in place?
So first impressions, these are difficult at the moment due to not having ridden it..I'll do doubt take it around the block at some point this weekend weather permitting. But initial impressions are good, it seems well built no major issues (will if the 2nd throttle issue stays away), at the moment I'm just going to remove all the plastics give it a once over and abit of a clean and tidy. Then I can consider the next steps... Firstly I think I'll be removing the SAS, evap completely I can't see the point in carrying about unnecessary stuff so they will be going. So a quick question for any tuneecu gurus if I remove the emissions kit add the blanking plates, block the air box hole do I just tick the SAI box in the tuneecu? same goes for the O2 sensors, they can be also can be deactivated in the program, what (if any) changes need to made in the map to supporting deleting the SAS / O2 sensors?
That's it for now, I'll post some naked shots of her tomorrow..

Hi Budd

Congratulations or commiserations – time will tell.
Watch out for the expanding fuel tank. I have to tilt the rear subframe back (by removing the 2 upper bolts and slackening the lower 2), supporting the tail from the ceiling, to get the tank off and back on. However, I have had to put helicoils in the subframe (made of aluminium cheese = easily stripped threads).

Don’t over tighten the air box cover screws – even easier to strip plastic threads !

Not toooo sure about TuneECU “can and can’t do’s”, but presumably what you turn off, you can then remove the parts from the bike and replace with covers/blanks etc.

Maybe get a dyno' re-map (eg. Dave Wood Racing)

Have fun……

Thanks for the reply, I also have a Aprilia RSV so I'm familiar with the expanding tank scenario, fortunately it came off no problem so
seems to be fine. I'll do more research on the tuneecu but so for it seems pretty straight forward, although I think the first map sent to the bike will be a tense affair... And yes when it's all sorted the final thing will be Dyno tune to tweak the map. I've just changed the gears over to a race shift which I prefer ( although I have an old CBR 1000 that's STD shift which makes riding interesting for the first few miles, it's easy to forget ...) Looking forward to taking it for a little ride tomorrow ?

They’re a great bike and I really miss mine from time to time..
When I bought mine it had the stock exhaust on it, I bought a full Akra off someone on here and got the tune ECU cable so I could load the map only to find the Akra map was already on it.

Had a brief test ride on it yesterday and it was it felt fine very similar to my Aprilia, perhaps a bit lighter and smaller feeling but other than that not night and day different. This is not a bad thing BTW I really liked my RSV and if this is like that only a bit more so then I'll be happy. 2 problems on the test ride, first my fault I've swapped it to race shift pattern and forgot to tighten the lock nuts on the pedal adjuster so lost my gears...simple job to reconnect it ( message to self tighten stuff as you do it..) 2nd problem the EFi light is still on flashing 72 so it's the 2nd throttle system playing up, I haven't bothered clearing the fault in tuneecu I'll do it when I load the modified map, and also try to diagnose the problem I think you can run a test to check secondary throttle operation so I'll do that and see if I can get to the root of the problem.
Test ride done I got busy stripping it down, here it is with its clothes of...





loving the Akra system not sure which 'evo' version it is but it's pure bike porn..


Also started the work I want to do before it is ready for the road, along with the usual service stuff I've decided to delete the SAS/evap, o2 sensors so I have new removed the whole SAS ( the evap was already gone so I need to check if the pipes have been plugged up correctly). After what I've been reading I was expecting a PITA of a job but SAS removal was pretty straightforward, no need to remove the air box ( which does look a nasty job) I found by dropping the rad a couple of inches, detaching the hoses it came really easy, just need to plug the airbox hole and wait for the blanking plates to arrive. Next job was the o2 sensors I've removed those to, ordered the blanking plugs (threads are M18 x 1.5 if you need any), so once the SAS blanking plates, o2 bings are installed I can delete them on the map via tuneecu and it should be job done, then to sort that pesky 2nd throttle..
Quick word on the o2 sensors, the rear cyl sensor (right in pic) looks Ok, but the front looks a bit rich.

so there seems to be a fueling issue, whether this is a TB balance issue or a map problem I'm do not yet now, Ill have the plugs out and see what they tell me, but I think once it's all back together a trip to the dyno is in order to get it checked out and tweaked as required.
Now waiting for bits, plenty of cleaning to do so won't be sitting about..

Yours looks to be the same as mine which I'm told is an EVO1 system.

And yes, getting the airbox off is a right pain in the arse. Just done it for the first time and it wasn't easy.

yes exhaust looks pretty much the same, does yours have 'for race use only' stamped on the band nr the outlet?

Made some progress over the last week, stripped it down some more. The bike as spent time in Dubai, and as a result it is covered in fine dust, this stuff is everyway not a lot just a light coating but it's in every nook and cranny so mine objective was to give it a good deep clean. So TBs out, air box off...

After reading various tales of woe re removing the TBs/airbox I was a little apprehensive, but it turned out to be pretty straightforward, the main problem is loosening the TB hose clamps, you only have a small access hole through which you have reach the clamp fasteners which in this case were 3mm hex (allen key) fortunately I have a decent selection of tools and found a 3/8 extra long ball headed 3mm hex socket spot-on for the job. But without this removal would be very difficult and probably nr impossible without damaging the clamps, so top tip if you're planning on removing the remove the TBs make sure you have a suitable tool to loosen the clamps.

tial section stripped down..

found some interesting wiring of the tail tidy this is someones idea of a good job (shakes head),

re wiring not sure what this large multi plug is ??? possibly an old alarm system, but it's not connected to anything so ultimately I'll probably try to remove it from the loom, not a priority at the mo so it will just get cable tied out of the way.

starting to get nice and clean

in the meantime some of the bits I'd ordered arrived, O2 bungs, KTM powerparts SAS blanks and some new plugs £15 each EEK, glad it's not the twin spark..

quick word on getting at the plugs, rear is a breeze but the front would be a pig with the air box in place, just a small access hole through which you have to disconnect the coil plug and remove coil before you can get at the plug, new plugs now fitted so should be OK for a good few miles now.
It's now back up and running, new map applied (well I say new map it's just the old one with the o2 sensors and SAS disabled) no fault codes so the modified map as done its job, not ridden it yet but it sounds fine, noticed on tuneecu the throttle is only at 93% fully open, will have to have a look at that see if it's to do with the cable adjustment, I've not properly reset cable tension/slack since I refitted them, or it could be something is stopping the butterflies opening fully?
Next job is to clean and refit all the plastics, better get started.

The multipin plug is for the KTM plug and play alarm.

IIRC There’s a routine in TuneEcu for calibrating the throttle. It’s possible the throttle is opening all the way but the full throttle position needs setting.

Thought it looked like an alarm plug, yes I'm aware of the tps setting method, once the new map is applied you turn the ignition on open and close the throttle slowly I think within 10secs then turn off and back on again and that should recalibrate the throttle, anyway did that and it remains the same, so I'm thinking it's either the cable adjustment or a hard stop on the throttle body, I'll check it out and see what can be done

Here is something I did to get 100% TPS, a while ago........

Unfortunately there is a problem with ‘photobucket’ and the new forum layout that has lost all but one of the images :(.
(My avitar used to be animated - L&H dancing - but thats gone now).

I'm not sure, I've only just taken it off. I'll have a look
View attachment 32281 View attachment 32282
mine says 'for race use only' right where as nosy copper may look if he decided it was 'a tad' loud (which it is with the baffle out),

I went down to see my mate earlier (bike MOT'r who'll be testing it in June) and he was saying something just as I fired it up and while I could see his lips moving whatever he was saying was completely drowned out. The MOT will be interesting...

Hi yes I read that post, it's one of the reason I checked the TPS in the first place, I'll get round to having a look at it before take the bike out properly.

well it was actually sunny today (cold but sunny) so with no rain on the horizon I decided to give 'R' and my old Aprilia a wash.




Pics taken before they had a wash hence all the dead flies on the ape..
