I like the idea, the concept. I think maybe the swingarm axel is a little small. I've been building motorized bicycles and was wanting to try to build a more reliable 4 stroke engine. I like the idea of the built in gas tank frames, but they are aluminum. Also there aren't any options for 4 stroke engines like the Honda GX series and predator type engines, only the 2 stroke motorized bicycle engines. I like the 2 strokes and all, but they aren't very reliable.
ofcourse huhulihin,kahit kumpleto ang papel niyan modification parin yan..meaning hindi mo pwede ilayo yan, pangporma lang yan..gagawa din ako niyan..rides rides lang sa bayan , tago tago ng unti, haha
