Twin power product was defective
I ordered this and got it installed and was defective. Part didn’t regulate the air. So when at start up motor shot up to 3500 RPM and wouldn’t come down. Until I put my finger where the air idle control valve sits in the throttle body. I can control the air flow and RPMs come down

Fixed my idle issues! I have a 2008 Dyna Street Bob; my idle would act up every now & then. Would run high when throttling off & would also low idle to the point of stalling. Isolated it to the idle air control valve. Tried cleaning it but no change. <br /> Once replaced, all idle issues disappeared & bike is running great!
