I've been working hard to find a Professional to assist you with your question, but sometimes finding the right Professional can take a little longer than expected.

I wonder whether you're ok with continuing to wait for an answer. If you are, please let me know and I will continue my search. If not, feel free to let me know and I will cancel this question for you.

Thank you!

Hi, yes the jetting,air screw and needle will possibly need to be changed to accomodate the larger cc, I would recommend getting this done professionally to avoid any damage with incorrect air/fuel mixture.
