Is the seal gone or is that some sort of smart air hole technology? I mean it cant be that smart as if I was to come off my bike petrol would leak from there when its on its side. I tilted the tank forward and petrol seemed to come from the ring of the tank cover. I think my filler cap seal might be leaking. Need some help with that Anyway with dads help got the full tank off, had to put some clamps on the tubes as theres no tap for some reason.īut I need some advice. Decided to make a proper topic about it here as I bet the topic I had in the general chat area was getting too mechanical for the admins likings Anyway Ive got the tank off need some help there Found a window for the tappets but going to have to take the head off anyway as i cant fit a feeler through the window Unbolted the flywheel cover But I cant take the cover off.
