Hi guys,
Newby coming online
I've looked for related threads but didn't find anything, so if one does exist, please just point me in the right direction to it
I've always had bikes (DT175, RD350, Ducati 750 Sport, CBR600) but they went staight to a workshop for servicing/repairs.
My new baby is a 1980 CB750K.
All went ok for a short while, but then it wouldn't start.
It went to a local workshop here in Spain, who check it out. They changed the 4 sparkplugs, cleaned out the 4 carburetors and handed it back working, adding I should close off the fuel tap every night! But it was soon on the blink, now firing up but with only 1 sometimes 2 cylinders. I suppose being so out of balance, there is a knocking sound. It starts up, but if I try to move it a little, it dies immediately.
Does anything stand out as a possible cause?
Appreciate any guidance
