Tri Zinger 60 Problems

[heyrod]

I have a 60 Zinger at times it get's really hot and stalls. Right now Iam stuck because I was playing with the carb and throdle cable and once the bike starts and I place the switch to run the bike is at full throdle and wants to race off with no control. I was wondering what could I have done wrong*****Please HELP my 7yr old son is really upset cause he has nothing to ride.

Thank You!!!

The reason it stalls is because it get hot. It is an air-cooled motor, and has no means of cooling. You have to shut it off and let it cool when it starts to do that.

Did you take the throttle cable and slide assy. out of the carb. ? If you did, take the airbox off and look inside the carb to make sure the needle sits in the hole correctly.

[heyrod]

Yes I did take slide assy out, that could be it huh? I will do what you said as soon as I get home. What if the needle sits in the hole oky!! What should I look for then?? Thank So much!!

[hondatrikesrule22]

It has happened to me plenty of times. If is is seated in the hole, check for any kinks or binding in the throttle cable. If none of that works, adjust your idle screw. But after you did the other two things.

[heyrod]

Ajust the screw on the carb? How do I know which one it is?? Sorry this is all new to me. Thanks

[hondatrikesrule22]

It will be on the left side of the bike (if you were sitting on it). It will be a screw with a spring on it.

[heyrod]

Okay I will do what you said first and then adjust the screw.

[MTS]

you might have also put the slide assy in back wards, tthere is a slit down the slider on one side, that should go to the left side of the carb, on the other side of the slit the is a little indent on the bottem of the slide, that should line up with the idle screw when you put it in, or facing to the left....also about the over heating, if it takes a long time to over heat then its just becuse it is air-coold, but if not it could be running lean(getting too much air), the best way to check this is just by looking at the spark plug after its been running, if it is running lean it will be a white colour, if it is running rich(too much fule) the plug should be a tan brownish colour, hope this helps some :D

[heyrod]

I did what you said and still after making sure the needle is in the hole it still idels high when I place it into run. There is two lines going into that one piece on is the throdle and one is the choke the needle lined up perfect. I dont know what else to do?? Any ideas????

[heyrod]

My trike sucks: Yeah I did notice the indents and slit on the piece and it went in correctly. Any other ideas???

[MTS]

turn your throttel adjust screw out a few turns..if it dose nothin, you could have some crud in the carb which is causin it to not seat the float needle properly...or an air leak somewhere...

[heyrod]

it doesnt have a screw. You think the needle is not sitting correctly? I looks like it's sitting in there the right way from what I can see. Iam stuck dude!!

[heyrod]

the screw your talking about would be near the throtel correct not by the engine or carb.

[MTS]

the idle screw i am talkin about should be on either the left or right side of the carb it is #17 in this picture http://houseofmotorcycles.bikebandit.com/partsbandit/assets/schematics/Yamaha/YA4940_06.gif wile it is running try turning that screw in a few turns to see if it turns the idle down, if that dose not help #22 is the air/fule mixture screw, it might need a turn in to decreas the air flow of the motor which could be causin it to rev waaay up, also 2 last things, you are running the mixed fuel in it right? and also the gas is on and it has lots of gas right? its just some times in 2 strokes if they are running out of gas they will rev way up like that :confused:

[heyrod]

Nice diagram. Okay I know what your talking about now I did mess with both of those screws and they didnt seem to make a diffrence. When I was fooling around with those screw's i had it in start mode i didnt put into run mode because when I do that the trike wants to race off. Should I try fooling with the screws while it's in run mode???? I had them both in all the way and turned the chocke one to 1 and 1/4 turn out and the mixure screw I turned 1 3/4 turn out and I was hoping it would do something but I didnt work. Yeah the mixture is right it's oil injected, yeah the gas is on and it has plenty of gas.

[MTS]

why where you playin with the throttel cable and carb in the first place?? was there something wrong? like was it ridin along and then it just started goin full out or somethin? also one more thing i thought of, on the carb slide assy there is the big needle on the bottem, make sure the retaing clip is holding it in so the needl dosnt push up when you put it in,,,,

[heyrod]

The reason I was playing with it because I was trying to see if any gook or junk was in it I sprayed Carb cleaner in there and I should of never fooled with it. When I put that piece back together and tried to start it back up again that's when it started raceing really high and then I grabbed the throtel and notice the engine wouldnt reave when I gave it gas. I guess that was stupid of me. So when I place the needle in it should not move up while iam putting it in correct???

[MTS]

yes that is correct the brass needl should not move up when you put the slide in, if it dose, you have to take the throttel cabel out of the slider, you have to compress the spring and pop the cable out and there is a little retaining clip on the inside of the slide assy, it should be retaing the needl, if it isnt just push in there good so it is retaing aginst the walls of the slide on the inside, thus holdin down the needle :)

[heyrod]

I think I understand what you are saying. Now the needle moves up and down when you hit the thottlle right??? I will try to do this when I get home from work!! I hope I can get this

[MTS]

yes it moves up and down when you hit the throttel/releas throttel, another thing,,lol when you sprayed the carb cleaN in the carb, is that when it started revin real high? becuse some carb cleaners caus bikes to rev real high, wile other cleaners make it bog out and die, if it did rev up, 1 turn the fuel off, 2 undoo the litte screw on the float bowl of the carb, some gas will start to drain out of a over flow tube on there, let it all drain out, then put the screw back in, turn the fuel back on and try that, reason i say this is there could have been some carb clean in the float bowl still.....

[heyrod]

yes that's when I noticed it once i sprayed the carb cleaner in the carb.

Where would i find the float bowl your talking about

[MTS]

it would be screw #26 on that diagram i alredy posted, man i wish you would have said that earlier lol, would have saved some time :\ o well just turn the fuel tap off and then un doo that screw, some gas will come out some where, just let it drain, then put the screw back in, i guarentee thats the problem, o well least you learnd some stuff about it now lol

[TTribaLL]

yes that's when I noticed it once i sprayed the carb cleaner in the carb.

Where would i find the float bowl your talking about


Float bowl is that thing at the bottom...the float is inside ;) (Tried to keep it simple).

[heyrod]

I will try it when I get home and I'll let you know how I make out :) Thanks Again

[heyrod]

My trike sucks: No good dude, I tried letting the gas out and gas did flow out but still the same problem.

[cliff2302]

i was gonna stay out of this cause i'm not sure what the run psoition is all about, but here's what i think. In that diagram, look at #14. Its the slide for the throttle. It allows air to come into the engine. Did you unscrew the trhottle from the top of the carb? If you did, when you put it back in, there are two notches on oposite sides of the slide which go around 2 small "pegs"(for lack of better words) in the carburator itself. If you dont line the slide up, it won't go down all the way. If you look through the carb, there should only be a small opening (1/4 inch maybe)where air can go through with the throttle closed all the way. Check that out and see if thats the problem.

[heyrod]

Yeah I did check that out and it sits in there really good. The piece just slips right in when the two pegs are correctly.

[cliff2302]

hmmmm, thats all i can think of. Can you tell us exactly what the problem was before and exactly what you did to the carb when you sprayed it? did you move anything, remove anything? how high does the engine rev when you put it to run? full throttle or just a high idle?

[heyrod]

On page one in the diagram there is a line that runs to the throttle like #9 I screwed that and made the tention tighter and loser once the problem started. I took off the piece #20 where the needle sits and sprayed carb cleaner in there. The reason why I did this is because the bike would start for a few mintues and then shut off other times i would ride forever. I thought i had some gunk in the carb. Every since then when I place the gas on and turn the switch to start, and then to run the bike is at full throttle and I press the thumb throttle in and it feels like I have no tention in it. I tried everything the needle is sitting in the hole fine cause I took the air box off and I could see it. The choke is not sticking cause that look fine to me too. I have no idea why it's doing this. Iam about to hang myself for trying to fool with LOL

[cliff2302]

From your description, it really sounds liike the slide is stuck up bcause that is really the only thing i can think of that would make the throttle have no tension. Make sure the cable isn't kinked or anything that would make the slide stick up. Thats all i can really think of. sorry

[heyrod]

no that's cool. I will check again but it didnt seem to be kinked. It's really wierd problem that Iam having. I might just take it into a shop and be done with it, my son is riding my a** about not riding his trike. Thank You

[Howard]

If you had the slide in there wrong you would feel a major difference on the thumb thottle. if you lok in the carb are you sure the slide bottoms out? the needle has to move with the slide and not on it's own. lok in the carb as you work the thumb throttle and make sure it opens fully and closes fully. what if the oil injection is working properly. running on to much gas? oil also helps cool the piston and such doesn't it? cuts friction anyways. could block off and pre mix a tank. does part 9 screw in or out?

[heyrod]

#9 is a small bolt and it butts up with a long bolt on the cable (if that makes any sense) On the slide piece it has one slit on one side and a groove indent on the other side and it matches up correctly when I insert the little piston. I havent tried turning the little piston around cause it looks like it will not fit, but I can try that. When I start the bike and place into run, it smokes really bad. How do I know if Iam running two much gas? Your saying I can do away with the oil injection and just go with gas mix in the gas tank? Will that effect anything?

[Howard]

I don't know a whole bunch about the oil injection, but i do have a lt50 and i pre mix mine and it is a oil injection bike as well. does fine on a pre mix. they do have oil injection block offs though.

[heyrod]

HUH does it run any diffrent? I will have to look into it.

[Howard]

No. doesn't run any different. oil injection just puts in oil for you. but if it's not puting oil in then it's running on just gas. just an idea, may not be but something to rule out.

[heyrod]

okay cool. Thanks I will look at the needle things, for some reason a lot of people thinks that, that is the problem but from what I can see everythings sits in fine

[Howard]

i was just trying to explain it a lil more. but the slide should come all the way down and all the way up. should not be able to move the needle without moving the slide up and down. both work as one. but i also said F you had the slide in backwards you'd notice a big change on the thumb throttle.
did you take the bottom off the carb? mess with the floats or anything. i dont have a clue about that switch that has start and run, never seen that before. does it have a cable that goes to the carb and when in start applies the choke? if so maybe look at carb, i think when in choke on that carb the little flap torwards the filter side will close? when off choke it is open.

[heyrod]

No i didnt take the bottom off the carb just that one piece. That piston thing should slide right in right? I will try turning it around and see what happnes hopefully it will work. What about the screw's on the carb how many turns should they be out? any idea?

[heyrod]

it's funny cause if the bike is off and I press the throttle I see the throttle cable moving but once I start it, I have no control of the throttle

[heyrod]

Okay I tried every which way but it only fits the right way the way I have it. I GIVE UP LOL
