Well, after a myriad of postulation and reasoning for possible belt squeal/chirp fixes, I decided to haul everything apart and "fix" it.....After placing the bike on a lift, I checked the pulley run out; about a mill+/-......Considering the only other force on the housing bearing was attributed to the cush rubbers, I decided to take about a mill off the tits that push out on the coupling assembly when everything is put together and the belt is in place......took the test run and checked again....just under a mill.......so.....I now know that the cush rubber has a direct affect on the torque and pulley wobble. Now for the "fun" stuff......what is the main problem?....I have a pretty good friend who's a machinist and had him have a look....first thing he says to me..That's a 6205 bearing?? Why is a single race bearing used when you have an axial forces(cushs pushing on the housing)? There should be a couple angular singles or dual race bearing in there to compensate for the axial force. So, now I have an answer to my problem....And the fix.................There are no 15mm dual race bearings that can be placed in the housing.......It has to be machined. The closest I can come to 15mm is 20.6 in a dual race bearing......So I buy a 3205 A-2RS1 SKF(double row) bearing....It's in the shop and being milled to the proper specs to fit. When I get this back and installed I'll post a follow up....Hopefully this is the "fix"....I did notice that the '06 VN2000 uses dual bearings in that housing, so maybe this will work!! Aside from the housing being milled the spacer in the hub has to be milled and the collar between the swing arm and the hub bearing has to milled to the right length as well. Let ya know how this works out in a couple days or so!!
