August 9, 20251 yr Evening all I’ve recently rebuilt the engine in the above mentioned bike and it starts and runs but there is a running issue. When it’s idling it seems to hold the revs just fine but if you give the throttle a blip at all, it seems to rev really aggressively and takes a few seconds to drop back to a normal tickover. Also on initial start up if you use the choke fully open it seems to absolutely rev its knackers off . I can tell it’s a fuelling/carb issue but unsure what to look for . Thanks in advance if any of you can help Kind regards Paddy Edited August 14, 20251 yr by PatMc Wasn’t clear in what I asked
