Hi and Happy New Year Folks.
Im looking for a bit of advice and guidance. Bearing in mind that as far as mechanics go I would class myself as a novice, so here I go
I tried to start my bike (400F) the other day with no joy, the battery was a bit low so put it on charge. I tried again this morning and still no joy, i removed all the plugs and cleaned them as they were a bit sooty and tried again. The bike started but was only running very roughly on 2 cylinders. I deduced this by touching the pipes and the 2 centre pipes were cold to the touch unlike the outer ones which were red hot. I checked the coils and one was warm and the other cold, so I am thinking that this may be the issue. Should I buy a new ignition coil or do I need to check elswhere? is there a simple diagnostic to confirm that the coil is indeed us?
Also just as a side note, I noticed after running the bike that quite a lot of fuel was leaking from the carbs. Other than that everything is hunky dory
