Hello all, new guy here. I just picked up an 01 with an FMF pipe, UNI foam filter and stock air box. It is running OK but I raced a guy with a bone stock 97 and he walked all over me. I did noticed a slight stumble off idle so I pulled the carb to clean/adjust it. I found a 130 main jet. If stock is 145 why did the first owner drop down is size? I ride any where from 4200 to 8000 ft in alt. Any ideas about what size main I should start with.
