No cold start/idle without choke

If it is the tail pipe popping a bit I wouldn't be too concerned. If the bike runs smooth otherwise I wouldn't touch a thing. But be warned that is just my opinion and have been wrong in the past.

The best way is with the bike at operating temp.Adjust in or out to were the bike idles smoothest.A little popping on the way back is nothing to worry about,but if you adjust further to the rich side (out),it should disappear.

I'm assuming your location is TX ? So you will be generally riding in warm temps, so if your pilot circuit and air screw is a tad lean it's no big deal. However those of us way up north who ride in the colder weather, the correct mixture and jetting of the low speed circuits is critical. Where you can get away with "lean" I can't. So I tend to adjust on the rich side . This aids in good cold weather start-ability, and proper low speed running while the engine is first warming up. So many cold weather riders complain that they consistently have to ride with the choke on for 15 min or longer until their bike will idle and run smoothly. This is the tell tale sign of "too lean" low speed circuits. I'm curious when you adjusted your air screw was the tamperproof plug already removed or did you remove it ? Maybe the previous owner had it removed.

Yup down here on the TX coast on an island called Galveston. I removed the plug myself. I then tightened the adjustment screw all the way closed, and then began working my way out .5 turns at a time, all the while listening to the motors response. In between 2 and 2.5 CCW turns, the hiccups stopped and the idle slightly increased and leveled out. I wasn't able to take her for a ride due to weather. Hopefully I'll be able to this weekend.

I agree- the fact that I live in a warmer climate should result in easier cold starts. That's why I feel that the constant need for the choke is an indication of a poorly tuned engine. I've owned multiple carb engines and I've never needed this much choke. Heck I don't even know where the choke on my lawnmower is lol!

1st used a ngk dr9ea plug the air screw should be set about between 3 to 4 turns
if the bike has been sitting long & lots of miles on it take the carb off ck if the o ring is on the front of the manafold by the head its probley rotted out now u can take the carb apart & ck all the passages & clean it well use oem suzuki parts only mine is set at 4.5 turns
I get 85 to 100 mpg
