sometimes if your havin probs its best to start again ie set all back to standard and start from the begining ,fuel go's off fairly quickly spesh if for arguments sake you have half a tank of fuel , the tanks vented i cant remember what shell told me but it will go off ,its realy about going through a methodical fault finding process ie fresh fuel,check oil ratio,check is the plug the correct heat/type ,check .not being rude but around the lawn/drive or blips up the street will not get the same affect as riding a track ,might not even get up to running temprature ,even when im warming my bike before riding it still needs a good clear out for the first part of the lap to then run correctly ,dont recon you will get it running right until your on a track! just my opinium not gospel. plug chop do a google search if your not confident i wouldnt try it......sorry for the spelling done in a rush!
