I have been toying with the idea of a belt enclosure for a while. As the weather has warmed and the level of dust in th uk has increased so has my belt noise. Been looking at after market Harley plastic belt covers, just not had a chance to do anything yet. They will need adapting and may not cover everything down there but could be useful. The other thought was rigging something up with plastic drain pipe parts. Won't last forever but may work as a proto type.
