here is a nice 2 stroke motor its a robin motor (new just bench tested to make sure it runs ), ive built a couple rc boats , and working on a 1/5 4wd truck now motors work great on all kinds of things . ive sold some of these locally and people modified pedal bikes and turned em into scooters , they also fit pocket rockets and mini atvs but look at pics trades are welcome for rc related items i ha
