I did a dyno and was getting horrible numbers with my 50 shot. Only like a 30hp gain and was dangerously lean ( like 17/1) So I pulled my jets and the fuel jet was clogged...It looked like a piece of salt in there. hopefully cleaning it out fixed the problem.

basically just throwing it out as a reminder that they do need to be checked
