Anything is possible but I doubt it with all new components. You should refer to the Reflex manual for installation instructions. What is your bike doing? Heating problems can be many things including thermostat or fan. Rich

Heating problems can be many things including thermostat or fan. Rich Yeh, and don't forget the wildly inaccurate gauges these scooters have as well. I chased an overheating problem for 1 1/2 riding seasons that didn't exist. Get a "laser" thermometer and check the head, thermostat housing, and radiator tank near the inlet temperatures. |

Thanks in advance. Check your PM's, trvstlh. I referred you to the HELIX manual as this is the engine the CF250 is cloned from. |
