Thanks for the input. I guess after my twisted cost analysis I'm leaning towards replacement

2nd gen. maybe

Karma bit me in the

yesterday am on the way to work when I had a catastrophic chain failure

DID 530 zvm, granted it had 13 k on it, but it split in the middle of a link down shifting at reasonable speed from 4th to 3 rd

Lunched my chain guard and got my attention right quick. So now she's in the shop for tune up , carb cleaning, and new drive. I shouldn't have said nuthin. Did I say I was leaning replacement?????
PS By the way Rob ths winter I took her plastic off and painted. She is now a beautiful red frame,tank, upper half of fairing , with flat black body, fender, lower fairing , side covers.and chainguard( RIP). I"ll post a pic when I learn how. Love that B4.
