Trying to find out engine serial number info. Contacted 3 dealerships and Harley customer service. Amazing no one can help. Number
CK37402106. I know engine has been replaced so doesn’t match number on frame. Any help appreciated

 

Can you post up a photo? This sounds like an older Sportster, can you provide a bit more information about year, model, etc? Also, what is the number on the frame? Is this a registration/title problem you're dealing with?

CK is an 883R, but there are some numbers and letters that should precede that.

frame is 2006 sportster 883. But engine been replaced with a 2007 1200 Efi so customer says

 

So, why do you need the serial number information? For what questions are you seeking answers? Please post up some photos of the numbers and the bike. Some background information would be helpful as you mention a "customer" in your post.

Something doesn't sound right.
CK=883R (2006)
3=1200cc
7=2007

In 2007 the model code for the 883R was changed from CK to CS.

 

This is a valid question. Why does it matter?

 

Looks like the OP was just a "one hit wonder."
