How do you adjust valves on Honda trx 350 es 4 wheeler?

Answer 1

There is no need to remove the top end of the engine...

Remove the gas tank cover. There are three separate pieces but it will come off in one piece. Remove the gas tank and plastic cover under the tank. Remove the spark plug. Remove valve cover. On the right side of the engine near the rear brake pedal there is an inspection cap that you will need to remove using a 6mm Allen wrench. Using the back up recoil starter, turn the engine over slowly until the "T" is in line with the arrow on the crankcase. This will be top dead center and the correct spot to do the valve adjustment from. Make sure that it is at TDC on the compression stroke by wiggling the rocker arms. If either is tight then you are 180 degrees out from TDC on the compression stroke. Rotate the engine with the recoil until the mark realigns with the arrow. Note: the arrow is more of a triangle shaped piece of the crankcase. The valves are adjusted using a flat head screw driver. The jam nut on top has too be loosened before making any adjustments and after. After setting the valve lash rotate the engine over 360 degrees back to TDC and recheck the valves. Valve clearance should be set at .

This must be done while the engine is below 90 degrees. If any of this does not make sense then it may be a good idea to let someone that has previous Honda experience do it for you.
