Where's the idle adjuster?

[motovert24]

i have a motovert 125[ to see what it is look at the fotm]
and does anyone know where is the idle adjuster because it is low?

its on the carburetor. most commonly on the left side of your bike. its the thing your air filter is attached to. it looks like a metal spring. it has purple marking on it sometimes and to make it idle faster turn it clockwise, for slower the other way. Also make sure your air screw is 2.5 to 3.0 full turns anti clockwise.

Man , that's like asking where the light switch for a room is in broad daylight !!!!!! ...

The idle speed screw is ALWAYS on the side of a carb dead in line with where the centre of the slide is ... They're usually big enough and sticking out far enough to allow you to adjust the idle using only your fingers ... It's simple enough to turn the idle screw either way slightly with the engine running to see and hear which way does what ...

Air or fuel screws are usually away from the slide ... either on the side near the air filter flange (AIR screw) or underneath at the rear near the float bowl (FUEL screw) ... and they're usually sunken into a recess where you need a screw driver to access 'em ... That's so they aren't easily knocked out of adjustment ...

on the mukuni carby (the one you have) it's the screw on the right hand side of the carby fondly enough the only visibles screw on the carby in is leaner and out is richer (fast and slow)

and makedonski who eva told you to set your mixture screw at 3 turns out has no idea and if it works on your bike you have serious jetting issue's

do i turn the idle up with the bike on or not and i haven't do it yet and how many time do i turn it

Yep do it with the bike running mate,
in neutral of course.

You don't need to turn it much at all.

1/4 off a turn maybe.

Depends how low your idle is.

Use the choke when the engine is cold or hasn't been run for a while ... DO NOT twist the throttle as you kick or it will not start until after you've kicked heaps of times ... then after a while you'll be whinging when your kick start mech stuffs up from gross over-use ...

When you open the throttle , the suction on the jets gets weaker as the slide is lifted higher ... so the vacuum is too weak to pull fuel thru to get the engine started ... it only pulls a slight amount of fuel at a time therefore requiring repeated kicking attempts until enough juice reaches the cylinder ... Anyone who needs throttle to start has got their carb set up wrong ... Cold engines need a super rich mixture because only a small amount of the fuel actually atomises into an easily combustible gas ... opening the throttle reduces atomisation ... It's a different case with an accelerator pump carb because the fuel is mechanically squirted in ... therefore bypassing the need for a high vacuum to get the carb primed ... In that case , one twist of the throttle squirts fuel in just as if being squirted from a primer or bottle ... But after that intial squirt ... get your hand of the throttle ... THEN kick hard ...

Kick the engine over until you hear it try to fire ... then you can back the choke off and it should start with no throttle ... Once it does start you'll need to give a slight bit of throttle to keep it going and help warm it up (if the idle is set too low) ... Once warmed , the engine should start first kick every time with zero throttle ... Once again , anyone whose engine does NOT start that easy when warmed up has got their carb tuning wrong ... as in the pilot jet is too rich ... or the carb is too big and has lousy air velocity ... Their bike will get annhilated by another with the same set up that has the right sized and properly tuned carb ...

The best way to learn how to tune to perfection is from racing bikes in bone STOCK class racing where the winning engines are subject to being stripped and checked ... that keeps most people honest ...

Always remember ... to avoid looking like a wanker repeatedly kicking your bike to start it and an even bigger one when your kick start mech fails ... Get your hand OFF it ... LOL ...
