Hi, I own a Pulsar 150 DTSi (2007). I want to know the correct/most effective technique for setting the idling speed and carburetor volume control screw setting. I have already read many articles on the web, but most of the techniques dont work exactly as described in these articles. Thanks in advance.

First and formost make sure air filter is clean.Then start bike and warm up engine.with engine warm adjust idle screw(the big screw with spring around it)Turn clockwise to increase and counterclock wise to decrease.with bike idling properly the low speed air adjustment screw (small screw located just above fuel bowl on side of carb)Adjust in small increments 1/16 turns at a time till bike has smooth throttle responce.This screw contols air flow during idle and up to 1/4 throttle.From 1/4 throttle and up the needle setting on plunger inside of carb takes care of 1/4 and up.You usally dont have to mess with needle unless you do upgrades to get more power out of bike.But over time the low speed settings can change due to wear on idle needle and air needle.So thats why you have to make adjustments.If bike still dosent respond or idle correctly I would purchase carb rebuild kit and your problem will be solved.
