What expansion chamber did you get?
What high compression head did you get? Did you check the squish band clearance?

Post a pic of your bike.
"high-performance" spark plug is a joke. Plugs do not add performance.
CNS is not a high performance carburetor as compared to the NT stock carb.
How fast did your bike go with a 44 tooth?

My bike went at least 25 miles an hour prior to that

Posting that very same question multiple times will not get you good answers.

You should check your squish gap, .025"-.035" is optimum for a 6cc head. Also, those short banana pipes are really not that good, there are much better expansion pipes out there. Does your engine have any 4 stroking anywhere along the throttle range? Also, weight is not a huge factor but how much do you weigh?
