Hi, I have a Suzuki C50 2006, i did oil change, new air filter, clean the fuel injectors, new fuel pump filter, treated gas tank for light rust, and bike still hesitates and shuts off , cant keep idle any idea, how $$ aprox.

The only way to know how much to fix is to contact the guys at Motorcycle Clinic and ask them.

Unknown i don't have the proper tools. I did what I could. Someone said it could be the regulator but I honestly don't know.

Hows your compression?
