Hello guys,
Not sure if this s thought forum but I am looking for a 350 engine to suit a 72 cb350. I have on which has a slight knock in the bottom end at idle, so thought if I can find a spare I can rebuild that and swap them over?

Are engine parts interchangeable?

is the noise there when you load the motor,(try "not" stalling 1st gear with brakes on??)b/ends are roller,not a job for the fainthearted,even mains are honda specific,(your'e gunna spend time on the interweb),trust me,

It seems to go away when i rev it up, I was concerned that if I strip it down and find something like a worn crankshaft, I will be with out a bike while i source parts. Is it a big job to replace big end bearings? Can i get rings and bearings readily?

why don't you sort out the knock 1st,does it go away with engine speed?,pretty robust b/ends,(up to a point),all 350 K series motors will interchange,pretty rare but, most are racing ,some 2fiddy stuffs the same,gears,not cranks but,good luck,
