I would have to guess that your jetting is way off if you're still using the stock CT jetting.

Check that timing isn't off one tooth.

what year is your motor? if its pre -82 you have the shorter rod and running a piston for a crf would keep the piston in the hole 2mm without reaching deck height, that is a huge loss in compression which would make it slow, i could be wrong though so let me know!

mine had the same problem, the race heads usually come with a size 95 jet, i got an 85 size jet and it ran perfect. also mess with the fuel and air screws on the carb those can help alot also.
