Where are you? Might be difficult getting anything on the BossK168. I can send you a Portuguese owners manual. Also check out the mopedriders site there are 2 there but for a 177 and a 192 I think. Check the Zundapp manual over there for the engine as they were clones and disassembly/repair is almost identicle. I have a 1994 Boss, It was a basket case when I got it. Photo in the pic section. Also have a bunch of different wiring diagrams for different configurations of mag set-ups. 2, 3, 4, 5 wire versions.
