Ct-1 piston was created by MarkT

First you have to know what you have.  You mention at least 3 different models...  CT1...  72 CT1 (which would be a CT2 and takes a different piston) and IT175 cylinder which won't fit any other engine except an IT175 without extensive welding and machining. 

The "CT1" is confusing because Yamaha used the same VIN prefix for the CT1, CT2, and CT3...  Do you have the full VIN number of the engine?  Check it against the tables in the Tech Library to find out what you have.

And finally, contact Enduronut and he should have the piston and rings at a good price for what ever model it turns out you have.
