After making up some new ht leads and putting in new plugs, I took it for a run round the block, about 5miles. Still running rough but not as badly as it was. Got home put it on the side stand while I opened the garage then noticed a couple of drips of thin oil on the floor, on inspection these seem to be coming from the head gasket. I got a torch to see if I could see anything between the fins, tiny fizzing bubbles on the head gasket (copper).
Obviously i need to get the head off and sort it, but would this account for the rough running issues I’ve been having. (Misfiring, back firing, reluctant idle, hesitant acceleration, puffing back through the carb).
I suspect the gasket has been leaking since I got the bike, as I noticed drips after my first ride but didn’t see where they had come from. Don’t usually use the side stand either so hadn’t noticed it dripping since that first day, until now.
Cheers you lovely people
