got a 76cb750k heap last month, and slowly progressing to the "test" phase. my plan is to start the bike and get it running sufficiently to check the transmission. don't care if the timing or brakes or lights are fubar, i can fix that stuff, but if the tranny is toast it's off to the "parting out" section.
got spark by repairing the coilL needed 2 NGK splice kits, and 4 new NKG plug leads. cleaned the carbs and was surprised how clean they were, hasn't been registered since 2005 or so. full disass down to the rack. replaced bowl gaskets and cleaned all pieces/parts and payed special attention to the pesky idle circuits. floats looked new, and everything cleaned up nicely. new fuel lines and in-line filter. borrowed wife's hair drier and softened up the rubbers and the rack popped right back on. no prob.
took off the oil pan and filter, cleaned all and replaced with new gasket and filter. pan was pretty nice, with no hard bits sleeping in there ,and the screen was good too.
today i reassembled the pan/filter and refilled w/fresh oil, tonight i'll rinse the tank and clean the petcock.
