The "Clog and Bog"
The stock chain guide "Clogs" with mud in wet
conditions . This translates into increased drag, Bogging down the engine and wearing the chain / sprockets.
The bogging is more noticeable with 2 stroke engines.
Note: Stock chain guard is
modified as shown below. To the right of the blade is used, as the "Bottom out rubbing block", for the chain.
