The idle jet is a fixed jet size and an integral part of the high speed performance
fuel is sucked through the jet into the manifold at idle but at rpms that circuit becomes empty of fuel and the air that is sucked in atomizes the fuel in the emulsion block of the carby and helps with burning of the fuel
so what you have indicates a blocked idle jet or if the carby has a idle jet solenoid to prevent engine run on when the ignition is turned off , check the operation of that solenoid

2013 Honda Activa will not idle when warm


Hi, P and the usual suspects are:
1. Idle speed improperly adjusted.
2. Air fuel mixture screws not properly adjusted.
3. Inlet system air leak.
4. Leaking accelerator pump.
5. Loose low-speed jet.
6. Plugged low-speed jet.
7. Contaminated or plugged low-speed circuit.
8. Enrichner valve/choke not seated or leaking.
9. Multi carburetors out of sync and need to be balanced.

My chainsaw starts and runs fine. After a short time cutting it starves for fuel and cuts out. It will still idle. The carb has been rebuilt and no change.


Take it back to whoever did the carb work. There are two jets on those, an idle jet which can be adjusted for idle speed, and the power jet that kicks in when the saw is under work load. You still have a problem with the power jet, either needs adjusting 1/4 turn at a time until the saw stops killing under load, or the jet and assembly is bad.

I took the stock air filter off my 2000 Suzuki Katana 600 and put a K&N air filter in it, when i accelerate it stalls out a bit before kicking up to speed. a slight lag then go.


Changing to a K&N air filter changes the air/fuel mixture for your bike, and you're probably hitting an overly lean spot before things start to even out. For bikes still running carburetors, which I think you have, you can compensate for this by changing to a slightly larger idle jet. Your main jet is probably fine (it's kicking in after the lag); it's the crossover from idle to main jet that's causing the flat spot.
Talk to your dealership parts counter to get recommendations about jet settings. They may suggest, for example, to keep your existing idle jet and go with a different main jet. Expect to try a couple different setups to find one that works best for your bike and your riding style. I would highly recommend keeping your original jets, though, in case you ever go back to the stock air box.

When the **** gets warmed up and you shut it off, you have to wait until it cools off before you restart.


Big thumpers are notorious for finnicky starts.

My stock '90 DR650RS needs to be started with a set procedure, generally NO THROTTLE when kicking over. I had same issue as you but reset air screw at exactly one and a half turns out and idle (warm) at 1200 revs.

Cold start: Hold de-comp on and kick over with 1/4 throttle, release throttle, pull choke and kick over once with de-comp still on. Then, turn ignition on, NO throttle, no choke, apply de-comp and kick over...let idle for about 10 seconds before grabbing throttle.

When hot: just kick over with hand well clear of throttle. (I use the handlebar cross brace for support)

This took me ages to work out but has been foolproof ever since, even after a spill in the dirt or a sudden stall in traffic.

I use premium Un-leaded fuel and stock NGK plugs with stock Mikuni carb and jets. I use two different exhausts (stock twin muffler and an alloy CZR single pot) and starting is identical procedure for both. (I only change the jets with exhausts)

Hope this assists, Cheers.

2004kx250f won't kick start, can push start. popping when decelerating, won't idle


idle jet has probably got blocked, there are two jets, an idle and a main, when your bump starting it is most likely using the main jet and when you decreas the throttle it is coming onto the blocked idle jet. take the idle jet out of the carb and check it.

I have a 82 honda cb750f. The bike runs fine with the choke on full.But with it off it pops and kicks. The tank is clean,the carbs are sinked.The carbs are clean in the bowl area.The previouse owner took...


Standard jets for the CB 750 are 120's, popping and kicking are usually due to running lean which is probably why it runs great with the choke on as that riches it up. I've run 115's with no problem but 100's??? Maybe was trying for better fuel mileage when gas was $4.50 a gallon?

My yamaha blaster will start and idle once i press throttle in it dies and sounds weird like its missfiring or something


Your mid and or hi speed jets are plugged. Drain the fuel (tank and carb). Dissmantle the carb, remove the jets and clean them. (Or soak the in carb cleaner over night).

Fuel turns to varnish in just a few months.

good luck

Just purchasted my Shadow and it seems to be only firing on one cylinder at idle. the bike was not run for 5 or 6 months. It will backfire when rev'd and the other cylinder will kick in spiraticly. Any...


Gas could be old, but it sounds more like you are losing spark to that cylinder at low rpm. Try a new spark plug, they're cheap. If that doesn't help, you could have a particle clogging the pilot jet of that carburetor. The pilot jet only works until you throttle it above idle. If it's clogged with a little junk, it will make bike idle terribly. Try spraying some carb cleaner through it (the one not running) with the engine on, and see if it likes the addition of fuel to that one cylinder. THis will tell you if you're lean on that jug. Good luck. Let me know. TT
