Thanks,great info I looked at my wifes roadster 1200 and it has no 1200 cc marks that I can see.
The convo i'm looking at I can't see any markings but might have to take his word for it I can't see removing the plugs to check bore being reasonable while looking

Jack up the rear wheel, take out both spark plugs

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 spark plug 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"

Ask for a receipt for parts added and work done to the bike.

1200 will keep up with a 1450 till it runs out of rpm -- 883 won't

I don't know how to tell if its been converted but I can tell you from work experience to look at all the nuts and bolts that are easy to see. This is the first step we use to see if a customer has done any work on the machines themselves. Cant hurt and wont mean it was a conversion done but its something that will give you some type of indication of work done. Look for any marks, nicks, or just any indication that a socket or wrench was used on that.
