Are both of the restrictors removed?

I would have to guess not, can you tell me where they are?

The first one is in the exhaust pipe where it meets the cylinder head. Take off the two bolts, drop the pipe and you should see a "washer" type restrictor. The second one is in the intake elbow. Take off the carb and the two bolts that hold the intake elbow two the head. Inside the elbow there will be a slotted restrictor. You may have to heat up the elbow to get it to come out. When removing these restrictors there is also a stacked pilot jet in the carb that needs to be removed. With the bowl off the carb you will see the pilot jet (smaller of the two), remove the lower one and leave the upper one. You will notice a big difference in power with these changes.
