Hi everybody, I didn't see a place to introduce myself, so I'll just do it here before I get to my topic. I'm an American, living and working in the highlands of Papua New Guinea. I'm a motorcycle and small engine (and ancient Land Rover) mechanic. I do not actually own a TW200, however, I do work on probably half-a-dozen of them for people in the area where I live, so I see them and work on them fairly often. I've been involved in this sort of work for most of my life, getting my start in the jungles of Peru when I was a kid, (I might want to talk to this guy who calls himself "peruano" sometime!)
Right now I'm "restoring" an older TW200 for a guy here who runs a coffee plantation. It had been sitting out in the weather for some time before it was brought to me and had been somewhat abused before it was parked. I've had to do a bunch of the usual stuff to it, new piston and rings, new valves, new camchain, etc. and have had to replace the seat and all the plastic. In the process of rebuilding the cylinder head, I noticed that a 6005 ball bearing is a perfect fit in the head where the big aluminum "collar" goes. What I want to know is, has anybody tried replacing that "collar" (as Yamaha calls it) with a 6005 bearing before? I'm going to go ahead and do it, I just want to know if anybody else has tried it. I've tried finding info on this on the interweb and that is how I discovered this forum.
Anybody?
