  1. Hi guys, my monster 821 oil level sight glass seal , developed a small weep . anyone here have same issues , and whats the process fixing such issue , is it a generic / regular seal or do i need to replace the entire sight glass
    Thanks guys
     
  2. Not expensive (on the 900) and comes with both parts. Maybe do at same time as service as you will probably need to drop the oil. You will also need a new gasket or 3-bond for the casing.
