Clutch & Throttle problem

Hello all,

I have a strange issue with acceleration after using clutch mostly around town low speeds 60kms.

Problem is when i use the clutch and release it to the grab point the bike will surge faster and then go to what i would call what it should have been slower. Hard to explain but i know its there 100% happens not in first gear but every gear after 1st. Also if i change gear with clutch and don't touch the throttle at all after a second or 2 it wont happen. Its defiantly a clutch issue there.

The bike has been dyno twice with tuneboy software, but i did not get it back like this. Its just started happening last two days

I have adjusted the clutch lever to see if that will fix it but it does not seem to help. Its not giving me that high rev sound because on release of the clutch the bike physical surges forward then what i would call normal.

Any ideas appreciated on what need to be done to fix it??

Thanks community in advance!

Check the clutch switch. There has been a lot of banter here on exactly what the switch does and does not do. I have the Brembo GP master and I have the switch unplugged. Plugged in regardless weather it was the stock lever and switch or the GP lever with the brembo aftermarket switch, connected, the bike gave me fits.

Check your clutch action...does it feel vague...if it does, bleed the system.

Clutch that has air in the lines, can cause some problems when you shift...engagement will not be accurate...causing sudden surging problems when releasing the clutch...

Bleed your clutch first being the first easy remedy, then go from there if problems still persists...

Let us know...

Kevin,
Who did your dyno work ? And yeah try bleeding clutch as suggested.

Hello all,

Thanks for the tips, i have since in the last day tested my bike, i dont know the reason or the cause but i can be a lot more clear on the problem

If i pull in the clutch slightly where the it should start giving me higher revs it doesnt. Instead the bike will constantly keep accelerating until i pull it full in then it will do what its supposed to do. So constant speed of 60km's i pull in the clutch slightly it will accelerate as if i was turning the throttle on slowly. I do have tuneboy installed with cruise control ( i know but its so handy!!) i am wondering if the computer is messing with me as well

I have been ridiing for x many years and never had this problem before.

Again thank you for the things i will try and see how it goes. Well let you know.

My bike was dynotuned in Port Macquarie Protech motorcycles

Thanks

Mine will momentarily accelerate when changing into second with the throttle fully closed. Only happens when changing into second and only when clutch is used. It is almost like the blipper is working on up shifts. Has happened from the moment I picked it up riding away from dealer. No issue when clutchless shifting

Well my local mechanic fixed the problem quickly, its the sensor on that switch which activates to give a cleaner quicker shift and acceleration and its very subtle so no one knows its working electronically. Apparently my ECU was sending false data to it make it accelerate a lot faster than it should be and was giving me bad surging while in gear changes. Easy fixed apparently and it is now not giving me and grief anymore.

Also off with the ducabike rearsets on with the rizoma's.. Rizoma soooo much better, i love the look of the ducabike stuff but rearsets i do not recommend with multiple bad experiences with them.

Thanks guys

Hello

I seem to have the same issue

Are you able to share what the fix was? I was thinking at first the bike is loosing power because of this sensor issue

if anyone knows more about this i'd appreciate any info

seems like the OP wasn't active for awhile so there might be a chance that we won't find out how he was able to fix it with the mechanic

the only fix i tried was jumping the clutch switch sensor (which made it smooth and felt way more powerful) but the quick shifter won't work anymore

any updates on this? mine is playing up and I'd love to know if this is the fix

The clutch micro switch on mine, once I got it operating correctly no more problem. Looked at 3 new bikes at the dealers...... all the same fault, lever pin not acting on the switch. There are many 1299s world wide with this same simple to cure problem.

Brilliant - thanks to this thread I diagnosed the quickshift and erratic engine revs problem straight away!! Started happening out of the blue yesterday morning. Is I drove away from home at slow speed firstly the quickshifter wouldn't work and secondly the revs would keep hesitating then picking up, like i was closing and opening the throttle slightly, which I wasn't. The bike is a bit lumpy at slow speeds at the best of times but this made it very difficult to ride.

You can also tell the micro switch has gone if you press the starter in first with the clutch out, the bike still trying to start - which it shouldn't.

Read this thread. Got home, took the side fairing and black infill panel off to get at the micro switch connectors. Disconnected and test it it. Basically the switch was stuck in the open circuity position , ie clutch pulled in.

After unplugging the switch all together the quickshifter and engine running were fine. The only issue I can see with not having the micro switch at all is that the engine won't start in gear with the clutch in, ie you have to get the bike into neutral.

So hoorah - bike back on the road

It does beg the question, what on earth is the ECU doing to the engine running based upon clutch position? Doesn't seam like a good idea to make the engine run like a bucking bronco with the clutch pulled in? Why make think so complicated??

Anyway - thanks to everyone on the thread!!

Check micro switch for clutch

Otherwise replace the clutch slave aus oberon distributer only has a red one left

I have the same problem on my new 959 panigale, can someone tell me where is the micro switch and what do i have to control?

Thank you very much
