If you run these bikes hard in muddy conditions without a mud flap on the front guard, then the front of the cylinder will quickly become clogged with mud.

This doesnt make a lot of difference if bike is being ridden slowly in trials application, but when piston crown temperature is very high due to sustained high rpm use, seizure on the front skirt of the piston will often result.

Its really a very good idea to fit a mudflap to any air-cooled bike thats going to get used in muddy conditions, as air-cooled cylinders really dont work very well at all when they are clogged with mud!
