2016 Honda PCX 150 valve adjustment
Posted: Sat Aug 07, 2021 7:14 pm
Just wanted to share some tips from doing the valve adjustment on the PCX I just purchased.
Note. Being 5 years old it had 850 miles when I purchased it and had about 1050 today,
I'm going to leave the 2 bolts and 2 screws that hold the battery box to the side covers off. The screw on the top by the fuel door and the two that bolt it to the underseat compartment should be plenty and make it a little easier next time.
The lower right side valve cover bolt and lower exhaust valve adjustment nut are a beach to get to.
I haven't seen this mentioned but if you remove the two exhaust bolts and move the exhaust out of the way there is much more hand room from the bottom. Made getting to the said bolt and exhaust valve much easier.
The intake was fine but the exhaust was way too tight. Of course the hardest one to get to. No special Honda tools for the lock nut and and 3 mm tappet wrench. I found a 11/32 wrench or socket fits the locking nut. 8 and 10 mm do not. Once the nut was loosened I adjusted it by hand.
I'm happy with the results and need to put everything back into it's correct place.
I had a 2010 Honda SH150 and it was much easier getting to the valves.
Next replace the 5 year old coolant and I should be good for sometime.
Hope this helps someone.
