  • motor recommendations

    Just blew up my big bore g230rc on my super bigfoot. Any recommendations for a new motor I had a Jetpro pipe so I would like a motor that the pipe fits. I looking for about 40-50 mph.

    320 or 290 could obtain 45 mph if built correctly, and that's with actual engine work. The larger the engine the larger the drive will have to be where a 290 could obtain it with a smaller drive. The 45 mph goal is very achievable Liquid cooled engines can be used with small PC radiator also, food for thought.

      DDM has black Friday pricing on the Zenoah G290RC. 3.5hp for like $220

      I decided to get one for the HD frame (DDM) ADA clutched sport I am building. The fact the engine already comes with the WT990 sold me.

          Just depends on if you think the cost is worth the extra HP. But seems DDM thinks you also need a clutch for the 320.

          320 $265 ~3.9HP
          290 $220 3.5HP

          The 290 is 36mm piston while the 320 is a 38mm piston.

          Per DDM regarding the 320:
          "For Go-Ped use - This engine will bolt on and work on existing 54mm clutch models. Will work on spindle drive models only if ADA clutch is used (part gt201)."
