Kz440 starter sprocket and clutch is the 78 kz400 a match

just got a kz 440c and it  needs a starter sprocket has any one seen if the 440 sprocket
Is the same as a 400 I can only find a 400  on line ,it looks the same in the photos but has a different part number

I am not claiming to be an expert on this subject, but from partzilla the part number 12046-1030 was used on both 400 and 440s.

Thanks that was really helpful I'll see if the bit is still on ebay

Turns out they are different 440 has a bigger whole

There are two different gears for the 400. One fits the 400A, D and S. The other gear fits the 400B and G models plus the 440.
