Vaibhav,

The two main screws for idle adjustment are the idle screw and the pilot screw. Check out your manual for pics. There must be a detailed explanation about idle setting with pics. The pilot screw usually needs 3 full turns anti-clockwise for decent idling. Based on the pilot screw you need to adjust the idle acrew. If you don't find the stuff in your manual, revert back and I'l type in the procedure here for you. A bit lazy now.

Running lean is NOT GOOD on any motorcycle/car, more so on CI bullets. Running lean means a lot more parts of air wrt fuel for the engine. Air cooled engines are cooled by atmospheric air and by the fuel mixture. Hence, a lean mixture causes overheating leading to a partial/catastrophic engine seizure in the worst case. The only advantage of running lean is that your mileage will go up, but of course at the expense of your engine life. Basically, you'll pay a heavier price than fuel savings if you run too lean for too long.

Cheers,

1. Lean mixture = Jay is correct. So I will not explain.
2. About Closing PAV = Go 4 dat first. Gud decision.
3. Tuning Pro.= I belive ur machine is Elec-CI350cc. So that means ur machine has 3 setting screw, carb = 2 tunning screws and emission controlling unit = auxy screw which is known as Auxilary Air Screw.
Step 1. Keep one table fan from front side for cooling the engine. (On High RPM, coz for newbie it takes some time to learn the setting, so engine might get overheat during the session, don't mind please)
Step 2. Engine should be warmed up for atleast 2 mins.
Step 3. Slightly increase the RPM so the bike will not stop.
Step 4. Close the auxilary screw which is given on the inlet manifold. Location of the screw is in between carburetor and head, one rubber pipe is connected to the same part , one end goes to resonator box(AirFilter-Chrome Plated) and another end of that pipe is connected to emission controlling kit. Equal tightening please coz we just have to close the port for some time. Do not over tight otherwise u may loose the threading portion of that alloy part.
Step 5. As u know ur carb is VM22, so the setting of Pilot screw or AF screw is in between 1 1/2 to 2 full turns.
Step 6. U should be able to feel some moisture from exhuast tail pipe.
Step 7. Decreasethe RPM by turning idling screw to lower side. Keep the idling till that point where vehicle should not stop. Due to no presence of RPM meter u can't get precise RPM number. So judgement......
Step 8. You are set with two screws till now. The next screw is Auxilary screw. Now u have to release the screw by unscrewing anti clockwise till u feel the RPM is getting HIGH. Auxilary screw increases the RPM. The point at which u will find RPM is high stop there coz if u turn it more RPM will go low. Exact point is the point where Left or Right turning will decrease the RPM. So that is the main setting point for auxy screw. Generally it comes near to 1/2 to 1 turn. depends on carb cleaning and engine overall condition.
Step 9. After setting up the auxy screw, again lower the RPM by turning Idling screw n set it near to 800 RPM.
Step 10. Checking the perfect idling

This way u are set to get good milage out of it. No lean no Rich. If u feel moisture or water droplets from exhaust tail then perfect setting. Sometimes u may feel chilled carburetor body.

Hi

Can anybody tell which are screws ? sorry.. I am sort confised. I am attaching the picture..

regards & thanks in advance

Re: Issues with RE Bullet Electra

Such nicely explained. I have never read a better and clear explanation. . I am facing the same problem with my electra. The bike refuses to start with the choke on; dies almost immediately. It then needs quite a couple of kicks and sometimes i even have to pull the fuel pipe and blow in the carb. The mechanic adjusted the mixture settings twice, but in vain. Now, i am gonna do it myself. Do you think, i should get the carb cleaned once??
