Valve Clearance adjustment

[krusty]

Ok. About two years ago I pulled the top end from one of my 1100s to see why #2 had no compression and I found a broken valve. I have now replaced the damaged valve and one other that was fairly poor. At the time I purchased a valve compression tool, as pictured. I am now thinking this tool will not work as it has only one "prong"(?) and not two as I have seen with others. The mounting holes do not appear to line up either. Is the tool with two "prongs" the only one that will do the job?

Yes the two prong is the only one that will work. You got a tool from someone who didn't know what they were selling. We see this commonly here. Motion pro sells that tool for cheap for the 1100/1200/1250 but it won't work.

That tool is for the 2-valve Yamahas like my old XJ650 Seca
