what to doo next? 2 new gears + balancer measurements

[boulder_adv_rider]

I installed 2 of the new sprockets--front balancer and idler. I'm still waiting on the 3rd to arrive. It took up some of the slack but still the chain is very close to the bottom of the case leaving little room for wear. The 3rd sprocket should take up a bit more slack but not much. And once you consider a bit of wear, most likely mine will be close to hitting the case. multisurfacemotorcycling.com has some discussion on people grinding the case to be more accomodative, but I agree this shouldn't be necessary. Seems to me the rubber damping material on these sprockets is pretty whimpy. My balancer chain is within spec (standard 190.5-190.9mm, mine 191.5, service limit 193.4), so I'm not going to spend $210 to replace it for 1mm. So even after I replace the last sprocket, I'll be curious what clearance I end up with. Already I have ok doohickey adjustability with the 2 new sprockets, but I can't help wonder if it won't be long before the chain is digging into the rubber sprockets again reducing the clearance at the bottom. Have to wait and see. I took measurements of two of the new sprockets (diameter of dampening material around the sprocket) in case anyone wants to know. I used a digital vernier caliper. Also, I measured my worn sprockets to compare wear. front balancer sprocket - new 46mm mine 45.25mm (section with most wearn/missing dampening material 44.90mm) idler (lower) sprocket - new 45.62mm; mine 45.30 rear (upper) balancer sprocket - don't have it yet; mine 45.15 I tell ya, a good business would be refurbishing the dampening material on these gears. The dampening material would be cheap and new these run $50-$100 each. Of course, the process to setup for refurbish might be expensive. Brian
