I've got the clutch assembly from an '86-87 TT225 for sale. According to this thread http://tw200forum.com/forum/technical-help/3261-xt225-clutch-tw200-2.html , it should let you convert your stock TW to a six plate clutch. I bought it for my bike just a few weeks ago but decided to just use a complete TTR bottom end so I am no longer in need of it. Price is $35 plus actual shipping costs, and I can send whatever pictures upon request. Thanks!
