couchcommando Posted March 11, 2014 Report Share Posted March 11, 2014 A friend has a GSXR1000K4 owned from new and done 7kmiles, we did a trackday 10 days ago and it ran perfect. Back home it was put on optimate till today when started up. Runs rough below 4k revs but clears above that. Air filter and plugs changed to make sure and still does it, battery is fully charged and charging when bike is running, drained tank and put new fuel in too. any ideas ?

couchcommando Posted March 11, 2014 Author Report Share Posted March 11, 2014 Thanks I think Seems to now be just on tickover it's missing and has now ran on when turned off...weird but maybe this is an air leak somewhere in or round the injectors/bodies ?
