There is some confusion about engine numbers - this table is from a barely legible photocopy I have. I find the numbers for 1975 a bit odd, and has anyone heard before of a T500A?
Other odd numbers have come up...this list is from Suzuki Australia, it may not show the complete world wide situation. Use it as a guide only.
There are some more numbers here
