Hello everyone - 750K2 & 550F1 are my 2 Hondas. The 550 has been in the family, owned by me or my brother, since around 1981. The 750 I bought about 6 yrs ago & is originally from US. Both in use, although recent issues with both! Carbs on 550 - stripped and they are in poor condition internally, may be looking for replacements. 750, suspect rear wheel bearings, noise from rear I originally thought was the chain. Will post pics soon. Based near Truro, Cornwall.
All the best, Malcolm
