Hi, trouble in a site,
here is a picture of crack at oil draining plug on the right lover front fork boot.
There is no oil leek , but l dont know what will happen once air pressure kiks in?
Qustion: ◆How serious this crack is?
Note: ¤Other visible lines are not cracks but leftover material from boot casting.

Thanks , Tomos <!-- s:moped: --><img src="{SMILIES_PATH}/moped.gif" alt=":moped:" title="cruisin" /><!-- s:moped: -->
