Hi! I am putting my 1976 GS750 motor back together. I seem to have missed taking ANY pictures between the motor sitting on the bench and after the jugs were off. 
Fortunately, I know a great group of people that are great at solving problems! 
(That's you guys) SO.... I have the head on and torqued down. Next step is to install the front (exhaust side) cam chain guide. As i understand, it slides INTO the "U" shaped cup screwed to the bottom of the case that "hugs" the chain/gear going around the crankshaft. However, after sliding it into the cup and bending it back (yes, it is under some tension, wanting to force the top towards the intake side. Not a whole bunch, though) so that the ears on the top of the guide can slide into the recesses in the head, I hit my snag. It seems like the guide is touching the cam chain. I can't tell how much and the flashlight causes some reflections and its hard to see down there. It may just be REALLY close to touching, I can't tell. Thinking through it, It seems to me that that would cause a lot of wear on that part and probably isn't right. I'm pretty positive I installed the "cup" correctly. As I recall, the other side of the cup has a small triangular divot that the rear (intake) chain guide mates with. I also cannot install the guide outside the cup as it would have to bend WAAAYYY too much to fit into the head. The only solutions I see are that it is installed correctly and I am worried about nothing, or that there is a slightly different way to slide it into the cup. Can anyone offer a solution? Something I haven't thought of?
