rear cylinder problem - SV650.org

17-05-06, 08:37 AM

It looks like there's something seriously wrong wth my sv650s k4 with only 5k on the clock. The first symptoms were the idle revs dropping and the engine cutting out when getting off the gas. I tried to raise the idle revs slightly and it seemed to work for a short while/ a few miles. Then suddenly the rear cylinder went dead. I managed to get back home running on the front cylinder only and once I stopped the bike wouldn't start anymore. So I changed the spark plugs (the rear one was slightly wet with fuel) and things seemed to work again except for the continuing problem with poor idle and dropping revs. Thought that giving it a ride with the new spark plugs will cure this problem but ig got worse instead of better and after 20 miles or so the rear cylinder cut out again. I can replace the spark plug again but obviously this is not the solution.

Did anyone have this happen to their bike? any idea what might be causing this?

Check you coils

As said above, check your coils, especially if it happening in the dry.
