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

Did you check TPS after adjusting idle?

No I didn't ? , I only turned screw 1/4 turn if that , I'm lossed with it as 85% of the time it's fine no issues at all , if things were out of adjustments would it not be a issue 100% of the time ?

Shouldn't need to touch TPS setting with idle adjustment of that amount, but that is of course assuming that it hasn't been messed about with in the first place?

If you're still having trouble then you may won't to have a look at this thread, particularly points 6 (CO) and 7 (TPS).

Thank you , ill put other plug back in and up co rating see if that makes any change , if not I think it's shop time 👍🏻

Update
Put it in shop the get it checked over nothing major found just need to take it out for blast , fingers crossed
