I ordered and recieved the 125 Jetmoto in good condition, assembled with help, and it did fire right up, but it don't want to stay running. So....what is the procedure for starting these things, I have not had that much atv experience anyways?

In what position is the choke on?
Do I keep the choke on and hold the throttle in to start and keep the choke on for a bit?
It's in the 80's and 90's now up here, so would I have to put the choke on?
Would a low battery cause it to not start?
Why after trying to start again after it stall does the starter click?

Sorry for all the questions, but I don't think I am doing this right, I can get it started and it will run for a minute and then it dies and wont' start unless it sets for a bit, then it will start but don't stay running very long. I really have not messed with it too much till this weekend, want to get it running before taking it to a trail to mess around on.

About the battery, does it have to be charged every so often?

Thanks for any help.

you have a dead battery, that why it clicks,
sounds to me you didn't charge the battery before installation, charge the battery with a .5-2 amp charger. with a .5 amp should take appox 10 hours charge time, with a 2 amp should take 3-4 hours, do not use any charger with higher than 2 amps, this is the biggest reason why these chinese batteries don't last . once the battery charged and it still doesn't start then get back to us. also you might want to conider buying and using a battery tender, these charge batteries automatic and shuts off when the battery charged , they come with a wiring harness that stays permanently attached to the quad so when you'll done riding for the day just plug it in, then it will keep the battery charged 100% while sitting and keeps the battery charged so their's no surprizes when you go to start the quad again no matter how long the quad sat. cost is right around $30.

 

[img]i/expressions/face-icon-small-blush.gif[/img]Hey thanks a bunch I did put it on trikle with my charger at 2amps, so glad I didn't go higher, and will let it sit while I work now for a couple of hours. That is a great idea about the battery tender, I am definately checking into that...I don't like surprises myself lol.

Thanks again for the quick reply, I am new, got a few things to learn I can see.[img]i/expressions/beer.gif[/img]

Walmart usually has a 'good' battery tender made by Schumacher for about $19. The key wording to look for is 'float mode'.

With a JM125 in warm weather, generally speaking, the 'start procedure' would be; check the sight glass on the right side of the engine for proper oil level (on the first start - every day), put the choke up all the way, then down about 1/2", leave finger off the throttle, crank engine over till it starts, let off starter button, depress throttle about 1/4", let engine run at this RPM for about 20 to 30 second, release throttle, move choke lever all the way down to the 'off' position.

The 'temperature' variables to this are; the colder it is, the less you move the choke lever down the 1/2" from full on (at 40 to 50 degrees the choke might need to be in the full on position to start and then after only 15 to 20 seconds of running moved down the 1/2") - AND the longer the 'warm up' 1/4" depressed thumb throttle period before the choke is placed in the full down 'off' position - as long as 2 to 3 minutes.

The 'beginner' adjustables on the carb are; 'start/idle mixture' and 'idle speed'. Both are on the right side of the carb right next to each other. The one toward the rear is the mixture and the forward one is the idle speed. After the engine is 'warm' you would first adjust the idle speed (basically as low as possible without it ever stalling - in first gear, WITH the hand parking brake applied [squeeze hand brake, depress plunger, swing little lever over plunder]) - if it stalls while riding, you just turn it up a very small amount - until it reliably doesn't stall under 'normal' riding conditions. It any event, after idle speed is set, with engine 'warm', ATV on level ground, in first gear, NO brake applied - the ATV should NOT move forward without depressing the thumb throttle - if it does then the idle is set WAY TOO HIGH

The 'start /idle' mixture screw can then be adjusted after idle speed is properly set. If it starts good and idles well - then you don't have to mess with the rearward mixture screw. If it is 'hard to start' - then you may have to adjust this screw. To start with - turn the screw clockwise 'inward' until a mild resistance is felt (DON'T turn it 'hard' against the bottom or you will damage the needle seat - just lightly) - WRITE the number of turns down on a paper !!! - ('normal' American carbs are always in the range of 1 and 1/2 turns for this 'base' setting) (my Chinese carb was only 1/4 turn [maybe mine was drilled badly during manufacturing??] ). Turn mixture screw back out counter-clockwise the amount that you wrote down on the paper. Now -with the engine cold - turn the mixture screw counter-clockwise out 1/4 turn (write it down) from 'base' setting. Try to start the engine. Did it start easier? If not turn it 'out' an additional 1/4 turn (write it down). Try to start again. Keep repeating the process until it either 'starts easily' or you are 'out' one full turn from 'base'. If it still does not start easily - return to 'base' setting and start turning the mixture screw inward clockwise 1/4 turn at a time (write it down) until it starts easily. AFTER - you have the start/idle mixture screw properly set up you may have to go back and fine tune adjust the idle speed again.

Thanks very much for that info, I was wondering about that too, so this was great of you to write that up.

It's running now, tried to take it out last night to about one of the only places we can ride around this dang town, but we didnt' even get out of the vehicle when we got there, cloud of skeeters they are so bad here now. They just passed a law that there are no atvs allowed in town or even riding in a ditch on the edge of town to get out, lol, but I might just sneak a ride out later and see how the 125 runs for me .

Excellent, that is a great link, thanks a bunch, not too bad of a price on them either, well worth it I would say.

 

I have a taotao that can start sometimes but then usually just stalls very quickly and i have been messing with the carb over and over again but it stalls out if i dont hold down the throttle and the battery dies if i start it again.
