96 Seca II Knocking noise... :(

[sammittrue]

Well I think I got suckered here. Recently bought this thing from a guy I recently met. Said it ran great last summer but wouldn't start this year. So I bought it and rebuilt the carbs. Fired rite up but than I noticed a very distinct clunking noise from the bottom end. 44k on the clock and I'm starting to see all the Mickey mouse fixes he had done to it.... so now I'm out about 900 bucks. Doh! If any of you guys are interested in parts let me know. I live in Portland Oregon
