1100stx

I've been on this forum just about all day looking around for answere's and maybe I've looked over them but I haven't found anything so far.


I've been helping a buddy with his jetski's and his latest 1 has become a puzzle for us, its a 1998 kawasaki 1100 stx, the HIN number I have to research the engine starts with JHT????? when I looked it up its not even a kawasaki HIN number unless I'm missing something.


We have been looking for performance upgrades for this engine as in kits and maybe how to port this engine to make it perform just abit above stock. he has the engine tore completely apart for rebuild so now its all about waiting on that special info any advice is appreciated!!!

OR maybe point me in the direction to get the info I need?
