Derestrict the variator

Look at the wear marks on the variator from the belt . If they are within 3/8 to 1/4 inch from the outer diameter then the variator may already be de ristricted. If the amount unworn is much greater 3/8" then remove the nut holding the variator on , remove the outer variator half, look for a spacer washer on the crankshaft. If there is a spacer or shim close to the outer half then remove it and place it behind the cam plate on the crank. Then reassemble . Your belt will now drive up further on the pulleys.
Also if you put a K N air filter on your stock carb re jetting is usually required.
