Andy J Posted September 15, 2014 Report Share Posted September 15, 2014 Ive noticed recently that the throttle response on my 5PW has got really snatchy at low revs and small throttle openings. It feels like the chain is really loose (It isnt) when you open or close the throttle at slow speed/low revs. As you transition from a shut throttle to open it really jerks. The same happens as you shut it again. Its fine higher up the rev range but round town and in slow corners its a total pain.It fuels fine everywhere else apart for the open/closed transition. I fitted a can and had a PC3 fitted and a custom map about a year ago and it was spot on but over the last few hundred miles this annoying quirk has developed. Any ideas as to what it could be? Im wondering if the TPS could have gone out of calibration perhaps? Im going to pop it back to the dyno place that fitted the PC3 to see what their thoughts are also.

MonkeyJim Posted September 15, 2014 Report Share Posted September 15, 2014 sounds like it could be TPS related and/or the throttle bodies need synchronising* *like balancing carbs, innit Link to comment Share on other sites More sharing options...
rossm Posted September 15, 2014 Report Share Posted September 15, 2014 Had a TPS go wrong on my 5PW earlier this year and as you say it was dreadful at sub 3k rpm but fine after that, expensive and a right fiddly pain in the behind to get in to swap them round Link to comment Share on other sites More sharing options...
Andy J Posted September 15, 2014 Author Report Share Posted September 15, 2014 Im really hoping its not a new TPS thats needed. As you say, a total arse to get to and it seems theyre around £190 new! Link to comment Share on other sites More sharing options...

I'd go for the throttle bodies myself. Had exactly the same as you describe on my 5pw a few years back cured by syncronising the throttle bodies. FWIW full Akrapovic, K&N and PC3r.

Andy J Posted September 15, 2014 Author Report Share Posted September 15, 2014 Cush drive rubbers You know, that did actually cross my mind. But why would it come on so quickly, its literally been over a couple of hundred miles. Bike only has 9k on it. Link to comment Share on other sites More sharing options...
Andy J Posted September 17, 2014 Author Report Share Posted September 17, 2014 Cush drive seems fine. Took it out for a run yesterday and it seemed fine. Very odd, maybe just operator error on my part! Not too fussed now as ive decided to sell it! Link to comment Share on other sites More sharing options...
