I have an ltz400 ’03 with white brothers E series slip on pipe K&N high-flow air filter no lid box. The pipe came with 165 jet and the settings from the instructions was ¼ open from stock., but now it is running to rich. I ride below 3000 ft. I am putting in dino jet kit and I need advice on which number jet to use for this quad and what settings to use.

Thanks
