Hero passion pro carburetor tuning exactly how many turns out from seated of air mixture *****?

Tel me indicator wiring details

Not familiar with the machine is it Indian made and what cc and engine does it have

Standard procedure is 2 and half turn anti-clock wise i.e. if the air screw is screwed in but care has to been taken when screwing it in do it very slowly and with less efforts so as not to damage the point.
Best to adjust this air-fuel mixture is to let the bike's engine reach normal running temperature than you adjust ...you can go a little plus or minus depends on many other factors.
Valve clearance too have to be checked and set according to the manufacturers specs. Hope this helps!

clen your carburetor and set the air
and clen spark plug.

how to open passon plus seat ?

The mixture screw has its main effect at idle.It is called the idle mixture screw. So may not help fuel consumption a lot.

To adjust it.
turn it in until it stops and count the number of turns exactly(so you can put it back if adjusting doesnt work)
Then screw it back out to the original position, and start the bike.
If you screw it out about half a turn, from the original position, the revs should rise and then become uneven, with the revs rising and falling(this is lean)
If you screw it in half a turn from the original setting, the revs should slow down and maybe stall the engine(rich)
Pick a place in between the two, where the idle is smoothest.

Of course make sure the bike is serviced first, clean or new air filter, new plug, new oil, adjust valve clearances(if it has valves) check tyre pressures, adjust chain (or replace if old)
The new air filter may make the biggest difference, as it gets dirty or old,it will richen the mixture right through the rev range.
And fix the shift key on your keyboard please.

Run the motorbikes engine to a normal running temperatue and thn set the air-fuel mixture by ...tightening all the way in taking care not to over tighten it as you may damage the tip of the screw,usually its thn 2 and half turns outwards or 3 , you will notice the change inthe idling of the bike's engine.
Its better to check the spark plug gap and also check the air filter, blow it with compressed air or if its tht dirty best would be to replace it.
Good luck.
