Hi, I have a 2020 Bolt XVS950. I looked at the spark plugs and both of them are white so that tells me its running lean. Where are the mixture screws so I can richen it up. I looked online for a carb diagram but no luck, I went to the dealer and two guys gave me three answers. It has a slip on exhaust and a Vance and Hines air filter if that makes any difference. A picture would help if someone has the same bike. Thanks for your help.
