The answer is tell us what track, your kart, your weight and the engine class you'll be in and you'll get a proper/good/ok answer.
--------------------------
We also don't know if what your on now at your regular track is correct.
Give us the same info about where you race now.
It's no use giving you info on a new track if what you explain about the gearing etc. at your normal track is ok.
With what you gave us you may be ok and a winner every week at your normal track but per your question you may need some help there too.
If your gearing is now off along with other things and you get good info for the new track you may be totally surprised how well you do at the new track.
Butt then when you return to your normal track it will be business as usual even though you saw improvement elsewhere.
All anyone wants to do on here is get fun and satisfaction hearing you did great after receiving some new ideas and maybe even ok advice.
