I have installed a 42mm mikuni BSR on my sportsman, need to know where I can get a hold of lighter throttle valve springs. Help would be appretiated.

 

I don't know about the throttle springs....they always seem to pull hard no matter what...I also understand that you can use a 37mm FCR carb (450R carb) from service honda for $175 or somthing like that in place of the 42mm BSR and get better throttle response from the powerjet
