24mm Carb which Jets to use

[Miker85085]

I just removed the standard air box and replaced it with a K & N style filter, also I replaced the exhaust with a performance stainless steel. That being said I have a standard 24mm carb on a 157QMJ engine with standard out of the box jets installed. I have read that now with more air flow you should not run too lean and replacing the slow and main jets to a larger size would be a good idea. I live at 1100' elevation and very warm weather most of the time (Arizona) what do you think if I install a #38 slow jet and either a #115 or maybe as high as a #130 main jet. Any words of wisdom would be appreciated.
