07 Bonnie Oil Leak After Engine Guard Install

Hello Rosser,

Welcome in ! First thing would be to remove the guard again and give the area a proper clean. When it’s dry and free from oil, start the bike and see if you can trace the leak. You might want to keep the bike as upright as possible without the possibility of it falling over. The reason for this is so that whilst it idles it’s not leaning to one side the entire time as it will have to run for a while to get the temperature up.

From here on you should be able to see where it’s coming from and action accordingly.

It’s a bit tedious but the right way imo. Let us know what you find.

 

Little hard for me to see in pictures, but I am wondering if this is not some damage previously undiscovered from dropping it ? I got to agree with Angus. Get it clean and dry by pressure.washing it, then start it up and see where the oil starts seeping first. I would especially check around the banjo fittings on the oil cooler and cylinder head. ...J.D.

 

The leak appears to be under the banjo fitting. You may have knocked it installing the engine bars.
Try turning the top hexagon bolt head a quarter turn maximum - an eighth initially and see if it stops. Failing that you need to replace the crush washers ...... unless there is other invisible damage to the hose or cooler matrix.
