Trouble putting Rocker Box Cover back on...

(1/3) > >>

Athame57:
I went to replace my newly painted Rocker Box Cover and like every second thing I take of this CB400F it doesn't want to go back on. It just will not sit flush on the cylinder head, close the gap on one side and it opens on the other. I can't see anything obstructing it. Referred Haynes to manual and saw there is sequence of bolt tightening to follow, ok...but 'make sure tappets are slackened first'... does this mean I have to slacken the nuts I see through the inspection covers? I can't think why. Not enough daylight to work where I am now so I hope someone can help for tomorrow?

Bryanj:
Remember whichever position the engine is in at least 2 valves are open so with the rockers in the cover and the valves in the head you are trying to open valves as you tighten the cover down. That is why you need to loosen the adjusters and be VERY carefull tightening down the cover

Nurse Julie:
Slacken everything off and hold tappets up out of the way with elastic bands.
