Anyone out there doing any porting? This is a biggie, although you have to manage the throttle with some discretion this was the biggest boost for my China engine. If I were to put an expansion chamber with the carb and ports I don't think the rest of the parts would hold up. I will not even bring up 4th and 5th ports. I wanna hear what you are doing. Have fun, Dave
