    I just finished building my bike i have a 49cc slant head angle fire motor with a 42 tooth back sprocket. I have great low end tork and it seems to top out at around 27-30 mph on the flats. I want to get a lil more out of it and was wondering what i can add on to it to get the most out of the motor without blowing it up. I have heard that the cdi is something that will help and also the exhaust can help with the back pressure. I have everything all stalk at the moment.
