Just got an 01 ds, already has woods pipe and tm-45 carb, my question is how can you tell if it has the light spring or not ? The pump is not activated . It runs really good, but that throttle pull sucks, so how can I tell? Thanks H.

 

I think you already told. If the pull sucks then it is the old heavy spring. With the lighter spring you won't notice the difference from the stocker.

Check your PM's.
