I've just had my Supersport injection in at Rapido to get the idle speed sorted - it was idling too low. Turned out that the throttle position sensor needed re-setting - it was reading too high.
Prior to that I had manually adjusted the throttle stop screw to bring the idle up a bit. It's located on the throttle side of the bike, and assuming your throttle bodies are the same (or similar) to mine you should be able to locate the throttle cable "cam" just inside the frame. The throttle stop shouldn't be confused with the fast idle stop - you need to check which bit the throttle cable is connected to, and make sure you get the throttle stop and not the fast idle ("choke" if you like). On my bike the throttle stop can be adjusted by turning a little grub screw, which is sealed with paint when it's set at the factory. I hooked the paint out of the grubscrew allen socket and tweaked it until the idle speed was correct. The problem wasn't properly sorted until I had the fuel injection checked and corrected by a dealer though - they had to plug it in to their Mathesis computer, which allow diagnosis of sensors, throttle position setting etc. Assuming it just needs re-setting it probably won't cost very much. Hope that helps, Nik |

The idle speed can be adjusted by the throttle stop screw, I can send a diagram if needed. However, normally the stop position is set measuring the angle or voltage output from the TPS and then the idle speed is trimmed by using the air -bypass screws, this is how I set mine and ticks over perfectly.
If the engine ticks over and picks up smoothly then just adjust the stop to get the correct idle speed (easy), if it is eractic or rough then it's best to check the TPS setting, vacuum balance of the throttle bodies, stop position and then trim the idle with the by-pass screws....(not so easy).

What is the suggested tick over speed?
