I have a stock ( fuelie 30cc HY3023549 ) engine in my XT an want to put a big bore kit on it?? Is it wise since I'm assuming this is a 2 bolt main engine? And if so what kit do I need??

I like this kit but will it fit? Don't see an HY engine listed on the page... Sorry if these ?s seem stupid but Im new to 1:5 scales an need all the advice I can get...


This is the link to the kit I like...
