Super Jet Help with identifying cylinders

[kawi_mods]

I have a full 62t motor out of a 95 wave raider that I bought to put in my ski and now I have the jugs off to port and polish. I ordered the yamanube port template for 62t but a friend of mine came over with his 61x port template from yamanube and they are the same template then we got looking at the exhaust port and the sleeve is lower than the port is this normal 62t sleeves or is there 61x sleeves in my 62t cast jugs? Thanks

Ok so the port hight is the same as 61x? Sorry I'm new to Yamaha stuff not sure the difference in 61x and 62t hugs other than the exhaust bolt threads and I thought port hight?

Exhaust port height is different between 62t and 61x

Yes, I only have one template for both 61x and 62t cylinders. The 62t 701 port is slightly taller than the 61x and slightly shorter than the 64x 760 port.

Ok that is what I was led to believe but how is the template the same if the exhaust port heights are different because you line the top edge with the top of the sleeve. Sorry I'm just trying to understand it. I have already started porting so I guess it doesn't matter just never seen the 61x to compare
