Having issues starting the S4 after the winter. Even with a new battery I had to get a push start, eventually fired up however felt like it was running on 1 cylinder.
Purchased a couple of new spark plugs and was about to fit today, pulled out the coil stick from the front cylinder and think I may have found the problem......
Pretty nasty! I understand CBR600rr sticks are the same, can someone confirm please. Looking at this an Ebay.
