Hi guys,
For couple of days, I was working on simple method to save fuel consumption. Check the photos . On first test, I made 4 turns of copper tube onto exhaust pipe. Then fuel from tank goes to copper tube and gets heat from exhaust then goes to carburetor. Did few rounds of testing on short distance with no problem. On first day of long drive testing from home to work (43KM) I notice some jerking like insufficient fuel to carb. After adjusting tube from tank then everything goes well with 10% increase on speed on full throttle. The motorbike was tested for 2 days before made further adjustments.
Yesterday, I made 19 turns of copper tube onto exhaust. Again tested on short distance with no problem but big torque improvements. Then today while coming to work, the engine jerks and stops. After few kick start, the engine stars back and after few KM again engine jerks and stops. I have no choice but to reconnect with original fittings.
I was wondering why this happens? Am I doing correctly of missing some important item? If anybody already went through this testing before, please advice on how to overcome this problem?
