Yamaha XT225 TM33 Pumper Carburetor Upgrade Installation Guide and Setup Instructions



Although the TM33 carburetor’s inlet and outlet flanges match those of the stock carburetor other dimensional and mechanical differences exist. The installation steps supplied in this manual ac- count for this and explain how to make a neat and clean installation that’s easily reversible should it be necessary to restore the bike to stock condition. Please read these instructions carefully, use common sense and good judgement during the installation process. Don’t force parts or over tighten screws and bolts. Make sure to turn off the fuel petcock before beginning the installation. Spilled fuel presents a potential fire hazzard. Don’t smoke around gasoline and have a fire extinguisher handy at all times. Do not perform this installation on a hot engine or near an open flame. Make sure to work in a well ventilated area at all times.
STEP 1 Remove the left and right plastic side panels that are in the center of the bike. These panels are held in place by pins pressed into rubber grommets on the frame up near the seat and a single phillips head screw down at the bottom of each panel. On some bikes the phillips screw includes a plastic shoulder washer and retainer to keep the screw with the panel. Back out both of these phillips head screws and make sure the panels are loose at the bottom. Pull the panels out of their rubber grommets and remove them completely from the bike. The soft plastic may bend a little near the seat during the removal process.
