To sync the carburetors on a 1997 Suzuki VZ800, follow these steps:
1. Warm Up the Engine: Start the engine and let it reach normal operating temperature. Then turn it off.
2. Access the Carburetors: Remove the fuel tank and any covers blocking access to the carburetors and vacuum ports.
3. Connect a Carburetor Synchronizer: - Locate the vacuum ports on each carburetor intake. - Attach the synchronizer hoses to these ports. If there are screws in the ports, remove them carefully and store them.
4. Start the Engine: Start the engine again and let it idle. Make sure the synchronizer is level and stable.
5. Read the Vacuum Levels: Observe the vacuum readings for each carburetor. They should be close to equal.
6. Adjust the Synchronization: - Locate the sync screw between the two carburetors. - Turn the screw slowly to adjust the vacuum levels until both readings are equal or very close. - Adjust idle speed if necessary using the idle screw.
7. Recheck and Fine-Tune: Rev the engine slightly and return to idle. Ensure the vacuum levels remain balanced.
8. Turn Off the Engine: Once synced, turn off the engine and remove the synchronizer.
9. Reassemble the Motorcycle: Replace the vacuum port screws, reinstall the fuel tank, and any removed parts.
10. Final Check: Start the engine to ensure smooth idle and throttle response.
Use caution when working around a running engine and hot parts.

For a 1997 Suzuki VZ800 Marauder, the valve adjustment specifications and procedure are as follows:
Valve Clearance Specifications (when engine is cold): - Intake valves: 0.10 – 0.20 mm (0.004 – 0.008 in) - Exhaust valves: 0.20 – 0.30 mm (0.008 – 0.012 in)
Valve Adjustment Procedure:
1. Preparation: - Ensure the engine is completely cold. - Remove the seat, fuel tank, and any necessary covers to access the valve covers. - Remove the spark plugs to make turning the engine easier.
2. Position the Engine at TDC (Top Dead Center): - Rotate the crankshaft until the piston of the cylinder being adjusted is at TDC on the compression stroke. - Align timing marks on the camshaft and crankshaft as specified in the service manual.
3. Check Valve Clearance: - Use a feeler gauge to measure the clearance between the cam lobe and the valve lifter or shim (depending on design). - Compare the readings with the specified clearances.
4. Adjust Valves (Shim-under-bucket system): - If clearance is out of spec, remove the camshaft(s) to access the shims. - Replace the shim with one of appropriate thickness to achieve correct clearance. - Reinstall camshaft(s) and torque to specifications.
5. Recheck Clearance: - After reassembly, rotate the engine by hand and recheck the valve clearances.
7. Final Check: - Start the engine and listen for abnormal noise.
Note: Always refer to torque specifications and follow safety procedures during engine work.

I guess I'm working on a 2003 vz800 I'm not understanding how to time it is can you put you put the rear on top dead center which is number one and then do you roll the motor over to top dead center for the front one and then set the cam to that or do you have to go another $180 degrees or what I don't understand
