Do the z400's have problems with stretching the cam chains? Just wondering becuase i just replaced mine becuase it stretched beyond service.
Yes, it is very common to have to replace the timing chains on the LTZ400's. The cam chain adjusters go out in them quick too.
alba makes an extension for the adjuster an inexpensive fix for about 13.00 and easy to install and has worked well on my wifes z440 so far.
