XR 400 valve adjustment

[QUOTE="mtngoat, post: 142124, member: 18818"] There are some tips, tricks and traps. I suggest getting a manual and the right tools. TDC can be tricky because it's easy to engage the auto-compression release, causing a bad exhaust valve adjustment (not something you run into on other valve adjustments). The thin Motion Pro gauge is great because there's not much room for a full size gauge; bent or otherwise. Beware though, my last Motion Pro broke off during an adjustment, leaving a piece precariously hanging in the adjustment area. I had to carefully extract it with forceps, hoping it wouldn't drop into the motor. BTW, get the big socket for the valve caps. I took the short cut and used a crescent wrench. The caps are soft aluminum and have tight access. There easy to mess up. There's more on this topic already posted. Do search on "XR4 valve adjustment" or try this link: [url]http://dirtrider.net/forums3/showthread.php?threadid=15315&highlight=valve+adjustment[/url] [/QUOTE]
