Honda Upper Engine Rebuild

well. i might as well show my progress on the honda.

a bit of history: i bought this 1971 honda cb450 sometime in '06. it never did run right. tried rebuilding the carbs, plugs, etc. no luck. actually it runs well; it just won't idle. (the left side idles, not the right). :P so i decided to adjust the valves and tweak the timing last week.... long story short, i royally screwed something up and it wouldn't run at at.

so what better time to tear it apart!?!





















i guess i started taking her apart around the 28th of may? after pulling the head and cylinder sleeves, i cleaned up the valves and head. they were a mess.










the valve seats were pretty pitted, so i lapped the valves/valve seats.
















currently, the top half is in bits all over. and i'm waiting for parts to arrive. i've ordered a new cam chain, full gasket set, piston rings and cams.






































i was debating not to get cams, but the lobes on the intake were a little smeared for my liking.























so i am waiting on those as well.
that's it for now.
