83 IT250K piston pin

[Tossa]

Ok the IT250K lemon that keeps giving, removed the old barrel and piston went to insert new piston and found the piston pin needed was a different size. The piston and pin removed were wiseco and the pin was 57mm long. I now need a pin I believe to be 61mm long. the Piston I do not know what make but details are on the face has CD and -010 printed and under the pin support has the number 504 and on the other one an indescribable stamp. If anyone has the original pin part 214-11633-00 could they tell me the length. Or can anyone identify the piston. Need pin and circlips, thanks Barry

.010 tells me it's  .25mm oversize made in the States and 504 is an dt250 yam engine prefix but didn't the piston come in a branded box?

[Tossa]

no came as a job lot with barrel and head. Guy who sold it to me didn't supply box and didn't know where or what it is other than correct size.

cheers

CD prefix on piston sounds like a wiseco piston.

have an optic at the wiseco part number listings.

been in touch with Serco, not wiseco.  Piston taken out was 4th oversize with 57mil wrist pin pistons for this model from wiseco stat 515.  Went to put this on and totally different length.
