What to jet my carb to

[dirtbikndad]

Hi, I have a stock 1996 warrior with supertrapp exhaust. I just bought this thing dirt cheap because someone dropped a nut inside the head and it destroyed the head casting inside and bent a valve. When I tore the engine down I found a nut inside the head and the timing gear key was shredded. I have it all back together and running. The carb is stock and needs rebuilt. What size main and pilot jetting should I use while I have the carb apart. The jets are stock but I think it runs a bit lean at idle. Thanks

I'd leave pilot stock and start with a 147.5 main. Do a couple plug chops and go from there.
