Crankshaft Balancer backlash adjustment screw

would like to see it too

Usually gears don't wear that much they need to be adjusted. I think it is there because it's easier and cheaper to machine the housing for the balancer shaft at the aproximated distance (less accuracy in the machining - cheaper and faster) and then make the final adjustment manually when all the parts are assembled. Then you can achieve a perfect adjustment, cheaper machining and in adition you can adjust it again after the wear caused by kilometers

Thanks Speed,
This makes sense to me now, cheaper and faster always wins out.

Can anybody explain why this bike has a Crankshaft Balancer backlash adjustment screw? This is the first bike I came across that uses one, and I understand why we have to adjust it. But why doesn't the crankshaft stay balanced? Why does it come out of adjustment? Why don't other bikes use them? It seems like Honda is cutting corners with this adjustment screw, because they couldn't figure how to keep it balanced without us having to do periodically .
Just saying........

Tomas, that's not correct. Other manufacturers and bikes have crankshaft balancing adjustment mechanisms. Suzuki on the Hyabusa, for instance.
Kwaka KLR650 is another.
Cheers
FJR1300 as well.

Didn't know that, I guess I should have said, that I never seen this technique use on 70's & 80's model motorcycles.

FWIW, the Honda Blackbird has dual balancers and the engine is dead smooth. I'd imagine that Honda could have given the CB1100 dual balancers but then it'd be too smooth, so a single balance shaft is enough to awaken rose-colored memories but not enough that hands would get tired of holding on to buzzing handlebars...

FWIW #2 my Blackbird has 75,000 miles on it, never felt the need to touch the balancer adjusters (the cam chain tensioner is a whole different story :-( ).
