Default Engine max went from 34mph to 25mph? wth?

I have a jackshaft kit, tuned pipe, and a dax 70cc engine. However today my engine started to act weird. Before it could hit 33-mph fairly easily. Now its struggling to hit 26-mph. What do you think the problem is? Chains adjusted right, bearings are good, just did a tuneup yesterday, and it was ok.
