Sorry for being a pain guys, but i have a bad hangover and this bikes stressing me out

what and how is the best way to adjust the TPS then and ill have a go when te rain stops?

Cheers
 
Do you have a multimeter and or can you use one? You really need it to check the TPS

The tps is just a variable resistor which vaires depending on the angle it sits at. You adjust it by loosening the screws and sliding it on the slots. You set the position based on its resistance reading which is given in the manual which you can download here. http://aprilia.vladiks.com/aprilia_docs/

If your not sure how to use a multi meter it is very simple and you could probably get one from maplin or probably halfords for a tenner. Get the maplin guy to show you how to test resistance with it and then just follow the workshop manual.

Right guys -for the record I sold this bike - I rode the bike the same day, a couple of hours, before I sold it and it drove fine - only took it up to 95mph in third addmittedly, on a fast run up a bypass, but it pulled perfectly up the rev range and did not miss a single beat -

I noticed a front bulb was gone on my way home (reflection in back of car I was following). I told the buyer that the bike had blown a bulb as soon as I opened my front door to him when he arrived. I wasn't prepared to start removing the front cowling for a blown bulb at that time. The buyer test rode the bike - this is what he said in an email to me when he got back home (over 200 mls)

"Ride home was a pleasure, Lovely bike and i am very happy, That rev limiter does kick in a bit harshly and a little earlie so ill have to adjust that, but thanks mate. very pleased with her, and i will look after it :D"

I have had the bike for a year with no problems or breakdowns, non starts etc etc - just cos Vinnyrsv has a pup and/or knows nothing about bikes he's bitter and twisted and very unhelpfully is winding up this young guy with his pathetic comments - name and shame etc. I don't have any problem holding my hands up and saying I sold this bike - it is near immaculate condition to look at and rode perfectly the day I sold it.

Vinnyrsv needs to know that I have been in touch with this guy by email since selling the bike, sent him several suggestions of what to do once I heard about the problem and have helped as much as one can remotely - I think its the alarm - and have tried to help , but, as he says he really is inexperienced and does not know what he is doing or how to test anything.

The people that are offering positive advice or to be commended. I am sure this is a minor problem and unfortunately has occurred at the worst possible time.

But don't forget - you and I don't know what has been done to this bike since it was taken away - what fiddling may have occurred and what of all the advice so far given has been attempted.

I asked the buyer to try several things and so far he hasn't actually told me what he had or hasn't done or tried.

When and if the problem is resolved, or not, I will discuss what to do about the situation with the purchaser - whether that's take the bike back, part pay for repairs or nothing. That is between us - as the purchaser said he test rode the bike - bought sold as seen - was told it had no service history or maintenance book (as when I bought it) and it was running great before he took it away.

Perhaps my bottom line is " If you can't say or do anything constructive - but out!"

I will not respond to anything the odd bitter and twisted members reply to this, if they bother - but wanted to set the record straight - either way I don't own an RSV any more and with some members of this forum I am quite pleased not to have to see such rubbish from them again.

Now what is important is to resolve the problem for this guy and that is what I'm going to try to do - so any help from the good guys - much appreciated - dumb negative F**k off!
 
I must say Clive has been replying to my e-mails and seems a very genuine guy. I did test ride the bike as mentioned and found no fault, how ever to notice this problem you have to be at the top of the rev range and where i rode it the traffic was to busy to go anywhere near them kind of revs, it was not untill i got on the M40 i had chance to open her up which then i started experiancing these problems.

I do hope this is a cheap easy fix as i do not have the funds at the moment for big bills.

I am not a mechanic and i don't really have the confidence to start messing things i am unsure of, Hopefully when i ring Griff monday i can arrange to take it to him and we can get this sorted, If he cant then i will simply have to sell it on.

The bike is very clean and i am sure when running right i will love it, I had many problems with all my 125cc Aprilias in the past, RS, MX, Tuono 125 etc and i said never again! i have owned a GSXR 600 K4 for 7 months before this and never missed a beat, I buy another Aprilia and straight away its a head ach.

:(
 
MY HID bulb went kaput recently and it caused my dash to go haywire, it was reading some stupid speeds (280MPH) and the tacho wouldn't go past 4000RPM yet the engine revved fine.

My two pence worth, replace that bulb first!!
 
Still done it with the new bulb mate

Right i am going to adjust the TPS now, shall i have the diag plugged in with the ignition on while i am doing it? also does the engine need to be running?
 
Ok i have disconnected the battery as i was told this resets the ECU . Still the same prob

I have slightly adjusted the TPF and the readings :-
Ignition on but engine not running . . 1
Ignition on with engine ticking over . . 0
When revving the engine and it starts bouncing around like in the video . . -1

Does that sound about right? way out? could someone shed some light
 
It may well be the TPS is knackered or come loose and is way out, you can only test it with a multimeter all of the +1 0 -1 stuff is rough guides and will more than likely not show a malfunction.

Assuming it is not really loose, ie enough to move it with finger pressure, then you need to electrically test it.

That said it of course may not at all be the TPS but its cheap and relatively easy to test.
 
you need a multi-meter as it's position is set by resistance, did you download a workshop manual?
 
go to the electrical section and look for checking/ adjusting the Throttle valve potentiometer
 
I know the object behind the forum is to help fellow members and further everyones knowledge of their bike, BUT, I can't help thinking that in this case perhaps the best thing to do is not to play with anything but wait for some input from Griff.

This could be a case of a little knowledge is a very dangerous thing. If Clive thinks it could be something to do with the alarm,then that seems resonable.

Trying to lead an inexperienced owner thru checking the TPS is possibly not the kindest thing we could do at this time.

Given his proximity to Tamworth a visit to Griff would seem to me to be the best option,before to much 'checking' or 'adjusting' is done.

Just my 2p's worth

I'm sure you'll get it sorted ok mate, just don't rush into doing anything you may regret.
 
i understand and agree to some extent but checking the TPS is working will not damage anything and it sounds like the bike is pretty unridable as is
 
Ian G i think your right bud, i would rather someone who knows there stuff have a look than me rushing to get it sorted, i can still ride the bike as is, but not really go past 8,000 RPM or it likes to jolt and scare me, lol
 
Yeah Griff is a top bloke ,, and stick with it ,, these bikes r fooking great !!!
Also my 2 pence i think Morepoints has been very reasonable these things do happen, its a piece of machinery, things have and are gonna go wrong, at anytime, thats why is a sold as seen.
 
Sorry if what I said ruffled anyones feathers,normally I'm all for getting down and dirty pulling things apart etc.

Somehow it didn't seem apropriate in this case. If you can ride the bike ok under 8000 rpm then at least you can get it to Griff who seems to be not too far away.

If it was your local Aprilia dealer we were talking about I wouldn't have suggested it,but having THE expert practically on your doorstep why not use him?

I'm sure that whatever he comes up with by way of explanation will be absolutely unarguable against so the less prodding & poking you do the easier things should go all round.

Good luck,and keep us informed :thumbup

Mind you,once you have this sorted and got some time in on the bike then I'm sure the guys on here will have you spannering like mad with all the things you can do to mod these bikes
