Joe do you know what part is actually rattling?? Is it the tensioner guide or the chain on one of the sprockets? You can actually tighten the load spring in 1/2 turn increments. I think I'm going to install the old honda recomended fix and add a 1/2 turn. Again I apologise for not telling you in a pm, really it didn't even cross my mind that you would want to know. The nagging fact is that if I put a new Honda CCT in there it will be fine for 2k,......... that spring has got to be losing tension. I dont think the chain or the gears are wearing that fast. I'll keep you updated on the status if you like. :wink:
