So I'm working on my very first top end rebuild. The bike is a 1982 xs400 Heritage Special.
I'm currently stuck on the acorn nuts fastening down the cylinder head. I can't get 'em to budge. Other threads I've browsed (here for example: http://www.xs400.com/threads/motor-tear-down-has-begun.6775/#post-69861) basically suggest getting more leverage, or best, getting a impact driver.
Given that I love any excuse to get a new tool, I went out and got myself a 12v DeWalt impact driver capable of 79 ft. - lbs. torque (not adjustable). I gave it a go, but I still can't even get the first bolt to budge. The plan is to loosen bolts in the sequence outlined in the manual, but I can't even get past bolt #1. Butts.
This is the first time this engine has ever been torn down. I know this because I actually had to punch out a copper plug securing a bolt which held the valve cover in place (a special feature of the Heritage Specials to prohibit tampering with the factory specs).
Alright - so here's the question - is my impact driver just too wimpy? What the heck balls am I doing wrong?
Thanks in advance doods!
