noob wondering what i have

[ss421]

And the jug and head are square not round if that helps at all....

Measuring the crank shaft diameter would be undeniable proof as to which engine you have.

[ss421]

Ok so i measure from where to where????

[eliteguy50]

Remove the kickstart cover. The front shaft that the belt goes around is your crankshaft. Measure the diameter of the end of the shaft.

Don't overthink this, Dawgs. Yes some Japanese AF05s came with the split belt cover, but otherwise the most visible distinction is the exhaust flange. If it points straight ahead, it's a SA/16. If it angles to the right, it's a SE/05. Evidently your engine's been modified extensively either way, but unlikely the P.O. Could get swap a cylinder from one to the other. Bolt spacing is different.

Do i have to remove the starter sproket ???
And yes there is a bolt on the back part of the kick start cover...and i don't think that is stock airbox upon removal it was held on by zip ties

If i can do it like as if i was taking of a power steering pump off a car and wrapping string around it and measuring the string it is 2 1/2 inchs... hope that helps if not just let me know

Neat you have an arrow pipe for an af05e, I also didn't know they had split covers for the kicker on some.

It's curious that the previous owner of a 1995 SA50 went against Common Wisdom:

Dude! He swapped OUT the Dio!!

Imported af05 explains the pipe.

The crank shaft diameter is 2 1/2

[eliteguy50]

That is the circumference, the diameter is the distance straight across the shaft at its widest point:

I need to check my math because I get a 20mm diameter from a 2.5" circumference.
