Recently I bought a 2002 Trail Boss 325. I was given a spare engine with it. I don't know what CC's it is.
The info I found on the pad in the front is :

ES 320 PFE102
329L
04-59666
Does the " 329L" mean a 330 or 325 ?
I tried everywhere to get specs for these numbers, nothing came up.
I want to rebuild the top end, and need to know standard bore size, or piston diameter.

Any help is truly appreciated

The 325 was 324 cc and the 330 was 329 cc

 

Thank you very much Sir........... !

 

I bought a trailboss 350l 4x4 order new top end now I see the top end I ordered is for 325. Any difference I hope not

 

Big difference - 325 is an air cooled 4 stroke - 350L is a liquid cooled 2 stroke
