How to identify CT70H Heads & Cylinders

42653steve · Jul 13, 2020

I have a CT70H Motor but not sure the head or cylinder is correct. Are the parts for a H model have different stamping on them then the 3 speed motor?

My HK1 has the same type markings on the head as the 3speeds.

Ok Thanks for the info.

I have seen more HK0s with "e10" than anything else. Have also seen "e9" and now and then an "e8". Honestly, I have not seen enough untouched HK0s to know for sure what they were born with.

Here is the pic of my HK1 head when it was being reconditioned. VIN build date is 9/71.

My engine came off of a 11/70 built bike that was 58 numbers lower than it's frame. Should have bought that as well back in '03
