Found this on my way back from jetski-ing..paid 170 only thing that is missing is the front fender.Seat is a lil beat up but other then that all good cosmetic wise.Problem is that it wont rev up.I switched it between run/start that makes no diffrence,Clean the carb which wasnt that bad.The guy who i got it from claimed it ran great till the kid played with the choke lever,which works fine.Somebody rigged up a light to it though,do you think that could be causing this?more pics later

I would bet a buck, the exhaust is plugged... Take a 1/2" drill bit, pull the silencer off the expansion chamber, and drill a half inch hole through the screen inside the expansion chamber... Re-assemble, and report back....

Before drilling, I would try to run it without silencer, and after without expansion chamber.
And I would inspect their inside: wasps often like to build their nest in small exhaust when they are not used...
You could test with compressed air to see if it's plugged.

well after doing some searching around i found out the exhuast are know to plug up on these.So i will be removing the pipe and trying to clean it out.One of the bolts for the pipe to head connection is snapped so i will have to remove and replace at work.Will be reporting back soon thanks guys

Ride Report: I got ride of that stupid screen and it opened right up.I like this better then My old alt 50 mainly because i fit on this thing.Sure is fun though.Beside pipes and reeds is there any other hop ups still on the market?

So it was the screen in the expansion chamber? There are 2 different gaskets where the pipe meets the head, one is a restrictor, and one isn't... PW50 clutch, aftermarket exhaust, oil injector elimination... (premix) There are a few nasty ones lurking around on the forum!

yes removeing the screen in the chamber seemed to do the trick.More searching around I do the more I see awsome zingers.Cant wait till i build this one up..The oil injection is gunnna be the first to go

Anyone have a pic of where this screen is located? I'm going to assume my exhaust doesn't have one because I didn't find one.. but, you never know..

cute looking bikes ive always like the little zingers!

Doug... The screen is inside the expansion chamber... Usually fouls up with unburned oil. If you take the stinger off, and ram a 1/2" bit into the expansion chamber... (through 1 layer of metal!)

Sorry for my bad english, but I didn't understand what is this screen and where it is located.
Could you explain it in more detail please?

I don't think my Zingers have some, but in fact I have never paid attention so I don't really know and I would want to verify...

the screen is between the expansion chamber and the silencer.
