Should I know something before trying to start? Like does the timing change because the CC change? or anything els?

[jmkjr72]

well the timing should be the same you used the plug that the kit recomends
now you may have to upjet the carb with the larger displacement so i would have a few new plugs on hand and do several plug chops

Oh I forgot to keep up on here, I got it running good but it sometimes makes a knocking noise when reving up. i'm not sure what one of these motors should sound like running to so i'm not sure if it's normal
