Porting 2 stroke Barrel. Yamaha DT 175

Описание к видео Porting 2 stroke Barrel. Yamaha DT 175

Doing a port and polish isn't hard to do! Smooth off rough edges and be sure when the two items mesh, they don't have any steps so the air can move freely from one chamber to the next. here the barrel outlet overlapped the casing chamber, so we filed away excess material so the transition is smooth. Still a little of polishing to do with fine wet & dry but you should get the drift of the video.
