srad34 Posted May 24, 2020 Report Share Posted May 24, 2020 Hi all, my pal has a ZX10R D model (07) and has only had for a couple of weeks. It's completely stock and was running fine until today when for some reason it's trying to idle at 6k after getting up to temp... It did it only once the bike was up to temp and once restarted it was struggling to idle but temp is fine, fan cutting in so thinking air/water temp sensors are fine. The ride back was fine and it's idling okay again.... 🤔 Whilst it seems okay now, I want sorted for his safety - The throttle has plenty of free play, no air leaks or trapped cables and seems to pull well if a touch jerky with WOT.... Thinking it could be a duff TPS as it's not very good on fuel (80 miles before light), sooty tailpipes but not mapped or got a PC - he did not notice any warning lights when it was revving its tits off...? Can theTPS be removed and cleaned or just replaced, it's got just over 20k on the bike... Or is it something else? Been on a couple of Zx10 forums and the answer to most problems is put on more rim tape and monster stickerz 🤣 Thoughts welcomed (as long as they are not smutty) 😝 Quote Link to comment Share on other sites More sharing options...
Alex_H Posted May 24, 2020 Report Share Posted May 24, 2020 Does the secondary throttle butterfly servo thing have a linkage to up the throttle stop a bit for cold starts? Some bloke on the internet says it does but I didn't see it on the fiche. Might be worth a look. Also, the bodies apparently have pilot air screws!

Hmmm, he's only had it a couple of weeks from a shop so unless it's something easy to sort, I guess it's going to go back.... It's the intermittent part that's the concern, if it was air or even servo linkage, would it not do it all the time? Quote Link to comment Share on other sites More sharing options...
Alex_H Posted May 24, 2020 Report Share Posted May 24, 2020 The servo's can go tits up but from a shop you say, I'd give it back to them asap, not fit for purpose an all that. Quote Link to comment Share on other sites More sharing options...
kja.busa Posted May 24, 2020 Report Share Posted May 24, 2020 If its under warranty it's someone else's problem. Could be nothing, but then it could turn out to be expensive, let them foot the bill. Quote Link to comment Share on other sites More sharing options...
Superdunc Posted May 24, 2020 Report Share Posted May 24, 2020 If it's idling at 6000rpm, air is getting in somewhere. Thats a mechanical issue first and foremost, not a sensor issue. I don't think these are fly by wire. Does it have an idle control valve? Quote Link to comment Share on other sites More sharing options...

I have no idea, it's not mine and not going to be doing the work, just trying to pinpoint possible causes with what it's doing, or was doing... 👍 Quote Link to comment Share on other sites More sharing options...
