so after spending a lot of time rebuilding the bike after a top end seize... it ran again last night for the first time. once i figured out that you need the choke cable hooked up to start it - it fired up first kick. good stuff.
as you might expect... after the first cb750 i'd ever ridden siezed the top end in the first week of our relationship - i'm a little paranoid about what noise is normal and what indicates problems out of the top end. what should i be hearing? it obviously sounds better than it did pre-failure... but that's not saying much, and it's certainly still making noise in the top end - but i'm sure some of that is normal and that there's going to be camchain noise no matter what one does. anyway - looking for some helpful advice from people who know these engines better than i do. what should i be hearing and what indicates problems? i don't hear any sort of ticking/knocking from the tappets or valves... but i hear what sound like friction and i don't know if it's just the cam chain rolling around or what... like i said - i'm paranoid about the camshaft operating and being lubed properly.
it won't idle without the choke holding the revs up.. so i'm assuming the slow jets are nearly completely clogged - as it chugs to a fairly quick halt after you let off the gas without the choke. it revs all the way up on all cylinders, though - which is very nice to see.
i'm off on my other bike for a couple weeks starting today - but i'll be right back at this project soon enough... should be only a few more weeks of work until it's rolling down the highway.
edit: it's a '78 CB750F
