Hi, is there some way to tell if an 883 has been converted to 1200?

Without disassembly you can measure the diagonal of the cylinder at Botton Dead Center and get a good idea. (provided you have flat top pistons)

http://sportsterpedia.com/doku.php/t...e_with_a_straw

883 ~ 5 1/2"
1200 ~5 7/8"

You won't know if you have 1200 heads, with the larger valves.

Since you are measuring to the edge of the piston, it doesn't matter if you have flat topped, dished, or domed pistons, does it?

Use a wooden dowel or chop stick to feel when the
piston is at the bottom.

Then push the bottom end of the stick to the far side
of the combustion chamber and mark the end of the stick
where it hits the upper lip of the spаrk plսg hole.
This is the diagonal of the chamber and it will be different
for a 1200 vs. a 883. Your measurements might be close to this.

For a 1200 it will be about 5 7/8"
For a 883 it will be about 5 1/2"

Be careful to choose the right one - They have them in 883 and 1200 versions - and aftermarket, they have them in 1250 and 1275 versions...

The main part measures across the cylinder diameter and the wire portion on the bottom will measure the depth of the stroke...
