I disassembled my 02' 220's KIPS for the first time yesterday, at least since I have owned it. I bought the bike used and do not know service history, but it was spoogy in there. When I removed the bolt that holds in the little ball bearing, I did not find a spring in there. There was the bolt, the bearing, copper washer, etc., but I swear no spring. The little bearing was sitting nicely in the indentation at the tip of the bolt. Bike was running OK before disassembly. Is it likely the spring managed to escape without me seeing it (search of work area has been fruitless) or is it possible it could have operated OK without the spring (meaning previous owner lost it)?
