The tri zinger.

IMO, a spacer wouldn't be worth it really without engine mods. not saying you might not feel a differance, just not as effective on basicly a stocker. i will admit i could very well be wrong though.

x2 on giving Raffa a hollar, he's the man to talk to about really opening up and modding the zingers. just about all the internal things were touched upon in some of the previous posts above. have read about a few things with lightening the flywheel and playing with the clutch weights and springs too for better reponse when launching if i remember correctly.

hey fabio, have you tried playing around with differant tire sizes yet? or is the gearing too far off to make it up that way?
the zinger i sold my brother is still factory stock and will probibly stay that way unless something major happens or i get a real bad itch that just has to be scratched. lol

The thing i wanna figure out is, when i accelerate, and i give it too much gas it burbles. I would like to know if its supposed to do that or if i can change that.

I'll give you one guess on whether or not it's supposed to do that.

Obviousy not, when got it, it would burble even worse. Then i put the needle in carb all the way to lean, and it fixed it more. But heres what i mean exactly, Say its idleing and i sitting on it in a field. I pin it and it takes off. it will accelerate for a bit then burbles. If i let off the gas a bit it will accelerate more. Idk what it could be. Ive tried giving it more air with a k&n air fiter on the carb, but could it be a jetting issue? My buddy keeps on saying that it does that to prevent it from revving to high and blowing up. Then he tells me if i lean it out any more it will blow up. Id rather hear some better opinons from people on here and not just him.

I get what you're saying now. These little buggers can be temperamental and sometimes they "load up" if left idling or if they're not up to operating temperature. When a two stroke "loads up", you have a buildup of fuel in the crank case that needs to be cleared out. With my Zinger, I hold it open and zing up to speed until the point of burbling. I then keep it pinned until it's cleared out. Now, don't do this to a cold engine. Take it easy until she's warm then let it rip and get it hot. If it never clears out, you're probably a bit fat on the jetting. Make sure your choke plunger is seating all the way down and it's not sucking excess fuel from there.

And your buddy is incorrect. These little buggers can and will rev to the moon.

Its worse when it starts but when it warms up it gets better, but not by much. Ill check the choke plunger, and maybe clean out the jets today. Whats the stock jet size because ill maybe go to my local dealer and pick up some smaller jets to play around with. I cleaned out my pipe so its not built up with crap too.

[riverrat]

I clean my pipes every morning

But seriously, have you read the plug?

[spentar]

Ill see when i get home because im in school. I ordered a new plug last night.

[spentar]

I went ahead and played around with it a bit. I warmed it up and played with the idling, and the other adjustment screw to the right of the idling screw. I got it to rev a very tiny bit higher, then i tried "clearing it out", i put the back on a stand and reved it up. Once it started to burble i just pinned it. It burbled for a while then just suddenly revved realy high, So i let off the gas and let it die down a bit. Then when i hit the throttle it started to die then reved again. Then i let off the gas and it dropped in revs until it died. I started it back up and did the same process until it revved realy high and stopped burbling. But when i let off the gas its just like i hit the off switch, unless i pin it again. After this i got on it and went down my street and it acted like it always has.

I put a 50cc Chinese top end on my wife's Zinger a year ago, and am very happy with it. I can also say that SETUP PROPERLY, they run better than a stock 60cc because of the porting. the ports are about twice as large as the Yamaha cylinders. Most of that addition opening was cut into the cylinder side though, so these aftermarket ones cannot be bored to 60cc like the Yamaha PW50. At the time I also got one of the $80 Chinese crank assemblies as well.

To use the China cylinder and get optimium performance, you need to open up the exhaust. I simply put a 250R silencer I had laying around on the end of the headpipe. This, of course is not nearly as good as using a pipe with an expansion chamber, but far better than clogged stocker. Then I found it was still hungry, and went to a slightly larger E-Ton 50 carb, I had laying around. Once It jetted it correctly, this thing will cleanly open all the way up and scream on the top end. On the bottom, it runs like a 60, but on the top, it is greatly improved. Also, I removed all the oil pump garbage, and used a plastic hole cap with a couple screws and washers in the pump mount holes to keep it tight and not leaking. I also got a handful of 39mm pod filters for a song on ebay. Oh, and i also took and old set of beat Boysen Reeds for a TriZ, and cut them to fit it as well. I used heater hose to couple the carb to the stock intake.

Yeah, it may be cobbled, but she runs super, and has lots of hours, and is quite dependable, and it didn't cost a fortune.

How did you get the eton 50 carb to fit? does anyone still have any ideas on why my zingers messed up?

[spentar]

update- So i cleaned the carb, and jets today, and im going to hook it back up in the morning and see if that helps. I got a new spark plug today, i just need to gap it. Im going to change the oil again, any suggestions? Im running brp full synthetic that i had extra of from my quad, and im sure theres a better option. The dg pipe will be coming with the next 2 weeks because my friend didnt come up to my area this weekend. Im still getting the burble. Could it have anything to do with how im mixing the gas? Im mixing it a 40:1 usually.

[fabiodriven]

40:1 should be a good mix. That's not your problem.

[spentar]

I looked at th plug and it seems dark tan. Maybe a tad rich. I have the needle in the carb all the way to lean. when i first got it i had to lean it out all the way to make it run like it does. So wouldnt it make sense to lean it out more to make it run even better?

[spentar]

Update: So i did the oil block of plate to eliminate the oil pump. It didnt do anything to make it run better but its now more reliable. I still cant get that burble out of it so im probally going to re jet it and see if that helps. Still havent gotten the aftermarket pipe but i will eventually. Not much else i can do that i can think of to make it run better than it is.
