would this be the same carb as the sportsman 500 in 01? anyone ever try drilling the slide out? this is the first ive heard of this

 

Basically the same carb as the Sportsman. Complete carb #'s are different mainly because of jetting differences. Sportsman has a 152.5 main jet,the Scrambler has a 155. Both carbs use a 40 pilot jet. Usually slides are drilled out when you install kits like Dyna jet. All this does is give the diaphragm a little more vacuum lift. Usually a small drill bit is supplied in the kits designed for this.

 

Is it worth a try? I guess you cant hurt anything. Thanks for your time lately

 

Before you do anything look at this link on cleaning and modifying the BST40 carb. The BST-40 Bible - ADVrider
Plus this pdf link is the breakdown and cleaning on the Polaris BST40 carb.http://www.google.com/url?sa=t&rct=j...,d.b2I&cad=rja
