So I hais 20 inch fit bmx im modding out and once I put another 20 inch front sprocket the chain gets super tight in a specific spot of the rotation, forgot to show the amount of slack the chains has but its a good amount, rides great though anyone know what it could be?

OR this if you have 4 bolt chain ring cranks…

Off center front sprocket / bent spindle /worn out bb.
How old is that chain?
Check out how the sprocket moves..its not running in a smooth circle. Take your cranks of and check if you have a spacer in your sprocket
It’s not funky at all, you just didn’t put the sprocket on with the adaptor washer. This is some industrial grade retartdium tbh.
Bent sprocket
Did you add the hat washer on the sprocket before sliding it on to the spindle?
