need some info on harness
i have a 1978 cb550k has the horn button with the PA button
i can get a new wire loom for K- k1 pt No 321000-374-000
but 76 model pt No is 321000-374-700
and 550f pt No is 321000-390-000
cannot seem to find pt No for 78 model is the difference just incidental things like the additional PA button if so is it easy to add additional wires to the new loom

After bying this bike i have done a lot of custom work and been going through and servicing everything on it. i hadnt done the rear wheel and notice that the front and rear sprokets were slightly out of line upon inspection the final driven had been rubbing up against the hub because the distance collar was missing
In the 500/550 wokshop manual on page 73 the pic with exploded view it is number 13 and is called distance collar B and in the parts list manual it is number 14 and is called collar B RR. axle distance
part no, 42625-283-000 so i will have to make one on the lathe and i obviously know the ID for axle and the OD that fits in the flange final driven bearing but i need to know the OD OF THE STEPPED UP FLANGE and HOW LONG THE STEPPED UP FLANGE ON THIS DISTANCE COLLAR IS that spaces between the hub bearing and the bearing in the ,flange final driven, as it is called in parts list so does anyone have one of these floating around that can give me the accurate measurement. would be much appreciated
cheers edd.

been spending a lot of time on the 550, now before i bought it i was told somewere down the line a 610cc kit had been installed but im not sure of this and removal of the head to try and find the problem i have of number 3 plug running very black and do valves and check pistons and rings etc as i cant find anyone who can supply a gasket to suit the 610 cc means if i pull the head off and it is a 610cc i cant put it back together any one have any ideas on measuring the cc or bore width without head removal or a contact for possible supply of such a head gasket
i have inquired david silvers and jerry collins with no luck

heres a question i was asked and couldnot answer
a mate of mine has a 500 four and had been out riding when he got home he said he put spit on his finger and wiped it on the top fin of the head and it sizzled do you think its running too hot he asked, i didnt think so in my opinion as these are air cooled and this got me thinking how do you know if your bike is running to hot

the frustration of problem solving can get to the best of us but once you find it frustration is replaced with accomplishment haha
well i had probs with my bike breaking down at 2/3 s, throttle and with the help of some of you guys i fixed this with the bigger jets but all through this no 3 plug has been running very black even before i jetted up the carbs when the other 1, 2, and 4, cylinders were lean no 3, was still black some one said may have a leak in inlet manifold but i figured this would make the plug show even leaner than the others , i could be wrong i done compresion test and doesnt seem to be much difference in all four cylinders but as i only had my old compresion meter hmmm lent the good one and wasnt returned lesson learnt wasnt 100% sure as i was thinking maybe stuck or cracked ring or valve problem possibly a sad spark from the coil even, by looking at the spark with plug out and held against the head it looks just like the other 3 plugs not an accurate measurement i guess, tried new plugs same result not to keen on taking the barrels off to check out in their before i locate a top end gasket kit not sure what the head gaskets on these are made off but from what i remeber on the old 750,s a lot of extras such as o rings and such to replace as well. this is the last problem with the motor left for me to fix then i will feel confident enough to take her an a long run looking forward to that
thanks for any info
