New plug , bike runs 85% of the time fine not a problem, today it's started cutting out when just reving it up , it still surges as if it's missing beats when trying to control throttle, if I ride it like I stole it you don't find much of a issue but as I'm now trying to keep to low speed limits and feathering low revs it's increased the problems , I'm lost with the issue now , but thank you again for your help
