2000 Honda 400 EX timing chain tensioner

I was wondering if i need to collapse the timing chain tensioner, and if so how do i do this, i am trying to put my 00 400 ex back together after installing a new piston?

One of our guys will g=answer your question soon... I'm not sure.

You will need to take the tension off the timing chain to put the top end back together. Here is a picture in which I have circled the timing chain tensioner. You can just remove the tensioner completely, or back it off with a tiny phillips head screwdriver. The adjustment is in the center of the cap on the outside of the motor that I circled. Take the cover off and stick the tiny screwdriver in the hole.
