So I installed this 50cc TCCD on my Pinto, paired with a tecno boss exhaust and a 14mm bing carb and intake. The top speed looks like it's right where I want it, but the low end is pretty terrible.
I used two base gaskets on the cylinder to make sure I wouldn't have a problem with the piston hitting the head the way people say TCCD's are prone to do, and I'm wondering if it's throwing off the port timing to the point where it ruins the low end.
I don't really want to mess with the gearing, because before the kit I had a nice range of torque and speed, and my top speed is good where it is now. I really have to get some more low end though, because I can't take off from stop signs without seriously holding up traffic.
I'm still tuning my clutch, so I'm hoping that might help a bit, but still, when the clutch does grab and the RPM's drop, I get zero acceleration.
