If you look at the photo above that is half of the engine case the balancers are behind the sprockets . So almost middle , I would say. Not being a smart *** this time , my balancers never made any noise that I noticed,before I removed them.

I believe the chain that drives the two counter-balancers (from the crank) has a hydraulic chain tensioner so I don't think the chain will be any tighter in a cold engine than in a warm engine.
NOTE: There are actually three sprockets: One on the crank and one on each of the two counter-balancers.

I'm beginning to think that the Beta motor was not the best idea in the world. Seems that the Alpha motor with the rubber mounting was a pretty good design.

Counter balancer noise
Great pictures. Would like to comment that most people do not realize that on roller chains when the outer links groove into the softer guides as soon as they groove to to roller part of the chain the wear stops and the chain rolls across the tensioners. I have pulled a balanced engine apart with 175k that had the same grooves but only the faintest area of wear were the rollers roll across. Also it may look like it would make noise but there is constant tension on the drive and little noise comes from it. Just a steady whirr. You can put a stethoscope on right side and listen.
