I hate to say it but the engine needs whatever jet that it needs, case in point these last two 650SX's I did first one needed a 95 pilot jet to run properly, no it didn't have an air leak, I pressure tested it , the second one has a 100 pilot in it right now, I may have to come back down to a 98 or 95 but I doubt it , the point is both engines are stock other than a choke delete and K&N flame arrestors, stock pilot jet is a 75

A head and p-flow won't change you jetting.

A 170 could be oversized, maybe. I had a high port 701 that was still over 1 turn out with a 170 main. Whats most important is that you can find peak rpm before the top adjuster is completely closed. Its not difficult but will take a few tries. Thats IF you know how the engine sounds and responds between being too rich and too lean.. Its a skillset that is a little different than just installing parts.
