I'm using a new YS 110 on mine. I need some info on the cowl and how to cut it. Do you cut any of the cowl off? I mean shorten it. I plan on using fuel dots for vent and fueling. Will they have to go through the cowl? My engine muffler is also going to be a problem. I'm thinking of just leaving it off and running a tube out the bottom of the fuse. Any help??
