hello ll i have a 1974 suzuki 125 that i swapped a 50 cc kids bike for anyway i got a question on the motor block its says 550cc i wouldnt think a 125 would have that big of a motor can anyone confirm this for me wether its original or not thanks
550cc would be transmission oil. If it is cast by the oil fill plug.
Look at the base of the cylinder there will be a number there.
I think on the right side just above the crankcase.It's been a long time since I saw one of those up close! hope this helps |
