Hey Rob... Before my "Do" headed for it's maker... I ran the vent off of the 100
all the way down to the wheel... Don't know if all the Saito's all like the 100, but
they do like to cover everything with my wasted fuel[&o]... It's seemed to work
well, with no known problems... And it worked great for keeping the "Do" cleaner
I think Barry hit it, with it running a bit rich.......
